HASHRATE of the 8 x 480 8GB Mining Rig!|12:15

[Bitcoin]

In order to maintain 10-minute block production rates with an ever-changing amount of miners and hash rate being produced on the network, the software programmatically adjusts block difficulty every 2,016 blocks, or roughly once every two weeks, commonly referred to as a "Bitcoin block difficulty epoch." This difficulty adjustment algorithm elegantly maintains an average block production rate, even with wildly fluctuating network hash rates. Over time, as more miners have tried their luck on the network, block difficulty has automatically adjusted upwards to compensate and stabilize block production rates.
Bitcoin network hash rate and difficulty history, linearly.
On the chart above, difficulty is seen as declining every so often after a reduction in hash rate, and increasing as hash rate goes up. If blocks are minted at a rate faster (or slower) than once every 10 minutes, on average, that would mean more (or less) computing power is being pointed toward Bitcoin than the difficulty threshold can accommodate. As more or fewer miners work toward the chain of blocks, the block difficulty target number will be changed to compensate, ensuring blocks are created at a rate of about one every ten minutes.
While we can clearly see the difficulty decreases on the linear chart, the above logarithmic chart makes the hash rate and difficulty drawdowns less perceivable. Historically on the Bitcoin network, block difficulty has trended upward and block difficulty reductions are rare. This is in part due to increasing mining equipment efficiency and effectiveness.
There have only been a handful of months over the past decade in which the block difficulty ended at a value lower than when it started. The relentless growth is even more apparent in charts that illustrate an average Bitcoin network hash rate by month and year. There has not been a month, year-over-year, in which the Bitcoin network hash rate went down.
Accounting For Seasonal Fluctuations.
So, now that we have established that the Bitcoin hash rate, over long enough timeframes, is aggressively NgU (Number Go Up), is there validity to the theory that seasonal fluctuations cause significant changes in network hash rate?
Per the chart above, it appears that the years 2020, 2019 and 2018 all saw average network hash rates trend lower toward the end of the year than they were in late summer and early fall. And what about other years?
Fall 2013.
For 2013, the network doesn't appear to have had a downward difficulty adjustment. This aggressive upward movement may be due to the revolution in ASIC effectiveness that was occurring during this timeframe.
Fall 2014.
For 2014, there were some difficulty adjustments downward during the late November timeframe. However, difficulty appears to be trending upward during most of the season.
Fall 2015.
2015 is a similar story to 2013: the network doesn't appear to have had a downward difficulty adjustment. More and better ASICs were being rapidly developed at this time.
Fall 2016.
So, 2016 sees a small difficulty adjustment downward around the October timeframe. Also, it appears that the growth of the network hash rate and difficulty slows down during the same timeframe, however, NgU.
Fall 2017.
2017 tells a similar story to 2016: network hash rate growth stalls and difficulty actually adjusts downwards a few different times. This is especially noteworthy, as price was increasing aggressively along these same timelines. However, these fluctuations may not be due to migratory miners. Along these same seasonal time frames in 2017, some major miners were forking off the network and manipulating hash rate to pursue other avenues.
Fall 2018.
The fall of 2018 may show the most obvious seasonal trend of difficulty and hash rate declining rapidly across the network. It's important to note that during these timeframes, the price was also falling from all-time highs. A significant percentage of the network, almost half, went offline seasonally. Yet, due to the elegance of the difficulty adjustment algorithm, the peer-to-peer network continued churning along.
Fall 2019.
The fall of 2019 doesn't show as significant of a decline as the 2018 season does, but it does show a few significant difficulty adjustments downward and hash rate reductions. It also shows a similar stunting of network hash power growth during the same time frames.
The Sun Never Sets On Bitcoin mining: Decentralization Continues As China Flounders.
Fall 2020.
So, this brings us to today. Mining centralization is a common criticism of Bitcoin and the narrative that many Chinese ASICs shut off seasonally appears to be valid for the fall of 2020. Where else would folks have about 48 Eh/s (30 percent of the network, as noted above) sitting idly by waiting for abundant and affordable energy? This works out to be about 3 million Antminer S9 ASIC mining units.
So, where does this dropoff rank among previous difficulty drops in the October and November time frames?
With chain data we can actually see that 2011 had the largest downward difficulty adjustment and an even larger month-over-month drop, occurring over a few different difficulty adjustments. This November 2020 difficulty drop is the largest we have seen in recent years caused by apparent seasonal fluctuations from enterprising Chinese hydroelectric miners. 2012 to 2015 did not see any difficulty drops between these months.
How do these seasonal difficulty and hash rate fluctuations stack up to the entirety of the block history on the Bitcoin network? The histograms for both the difficulty adjustments and hash rate changes offer some insight:
Is This A Bitcoin mining Death Spiral?
When the network hash rate or price of bitcoin goes down, there is always much speculation on the possibility of what is colloquially referred to as the "Mining Death Spiral." The claim goes that if the price drops low enough, miners decide to shut down and the network loses a sizable percentage of its hash rate. This would force some miners to liquidate their earnings, pushing market prices lower and furthering this vicious feedback loop until a death spiral ensues. For a network like Bitcoin, this would result in miners shutting down, blocks ceasing to be mined and the timechain ceasing to propagate -- Bitcoin would fail.
However, as an example, Dogecoin ($DOGE) is still minting blocks, so this doom and gloom theory may not hold true for these types of distributed systems. There are many enthusiasts, fanatics and "miners of last resort" that will maintain some of these systems simply for the sake of maintaining them, and the faith of belief.
So, let us imagine if 50 percent of the miners stopped mining right at the difficulty adjustment block and shut down; what would happen?
It would take the remaining half of the network about twice as long to find the 2,016 blocks. This would mean four weeks, or about one month, to get to the next difficulty adjustment point. What would the ramifications be for the network?
The mempool would begin to build up, transactions would become delayed and fees would increase as folks bid up new, even more scarce block space. This is actually exactly what we have seen for a few days after the hash rate recently dropped off.
However, the Bitcoin network eventually adjusted difficulty, as it has each time that 2,016th block has come up in the past. This difficulty adjustment algorithm is a very elegant solution to a few different challenges facing the Bitcoin network, and because of these types of solutions, the self-regulating system continues to propagate forward.

Are Chinese Miners a Threat to Bitcoin?
Is the concentration of hashpower within the borders of China a cause for concern about a nation state attack against the network?
Jameson Lopp.
Read more posts by this author.
Ever since the industrialization of Bitcoin mining in 2015 we've heard concerns about the concentration of hashpower within the borders of China. Why is hashpower concentrated there? For one, most of the world's semiconductor production facilities are in Asia and thus most of the mining chips are produced there. But perhaps more importantly, China has an abundance of cheap energy.
While there are dozens of countries with incredibly cheap electricity, in general they are not sufficiently industrialized or politically/economically stable enough to support large scale mining operations. China is one of the few countries with the combination of infrastructure and energy abundance.
Much of this mining power operates at 2.5-3c / kWh in Inner Mongolia during the dry season via cheap coal and wind power, but during flood season, these miners migrate significant capacity to Sichuan and Yunnan provinces to take advantage of 1c/kWh hydroelectric power. Quite simply, there is more power generated than there is demand for consumption, which results in very low prices.
Hashpower Distribution Estimates.
The Cambridge Centre for Alternative Finance estimates that in Q1 of 2020 70% of the total network hashrate was in China. Note that these metrics are based upon several assumptions and their accuracy can't be verified.
Though the hashrate is spread throughout the provinces of China (not evenly of course)
A CoinShares Research report from December 2019 placed 65% of global hashrate in China.
In July 2020 a study that was commissioned by the Fidelity Center for Applied Technology released a report that estimated closer to 50% of global mining power capacity is likely in China. However, they noted that mining is a secretive industry and they believed they were only able to identify 15% of Chinese mining sites.
51% Attacks.
Why do people get concerned about more than half of hashpower being located in China? Because of the infamous "51% attack" against which Bitcoin is susceptible. The interesting thing about 51% attacks is that they don't break any of the rules of machine consensus. So what are the ramifications of pulling off a 51% attack? It somewhat depends upon the motives of the attacker.
Despite its scary-sounding name, a 51% attacker is limited in what they can do:
They can't steal people's bitcoin arbitrarily They can only actually double spend their own bitcoin They can't change the consensus rules They can't make invalid transactions become valid.
If a 51% attacker is seeking to maximize their profit then the juiciest target for a double spend is going to be an exchange. Mine a bunch of coins, send them to an exchange, convert them to a different censorship resistant cryptocurrency or stablecoin, withdraw those funds, then release a bunch of blocks that were mined in secret that send your original UTXOs that were spent in a deposit to the exchange back to your own wallet. The downsides to such an attack:
Any exchange with decent liquidity to make them attack-worthy will likely have withdrawal limits Similarly, most such exchanges will require AML/KYC and thus you'd also need to compromise a verified exchange account with high limits The value of the bitcoin you still hold after the attack will likely have decreased substantially, thus a successful large attack could actually result in shooting yourself in the foot. You'd better not slip up while you're accessing the exchange you target. For example, one hacker returned $25M in stolen funds after leaking their IP address.
It's certainly safer to just use your hashpower to profit from securing the network rather than attacking it. But what if the attacker doesn't care about profitability? What if the attacker is a nation state that prints their own money?
A Nation State Adversarial Miner Attack.
There are probably a thousand+ mining farms scattered throughout China; it would take some effort for the government to seize them all. I suspect it would be nearly impossible for the state to start seizing control of mining facilities without the news leaking to the rest of the world. If we heard of such activity taking place, you can be sure that Bitcoin stakeholders would start planning emergency actions.
An easier attack vector would be against mining pools; at time of writing it appears that over 70% of hashpower is being coordinated through fewer than 10 mining pools that are located in China.
Of course it's far more feasible for a nation state to identify and attack 10 targets within its borders simultaneously than it is for them to attack a thousand simultaneously.
On the flip side, switching mining pools is incredibly easy for miners. Once again it becomes a question of being able to perform an attack covertly. Given how many independent entities are observing activity on the Bitcoin network, it's practically guaranteed that within a matter of minutes an alert would be sounded and miners would start looking into taking action against malicious actors. At time of writing we even have Twitter bots that put out alerts about any orphaned blocks.
At 22:17 UTC on 9 July 2020, Bitcoin had a stale block at height 638,519.
The losing block contained 2,384 txns:
* The coinbase txn * 2,377 txns which made it into the winning block * 6 txns which made it into the next block.
It's hard to imagine a scenario in which a state actor would be able to quickly and covertly seize enough hashpower to perform an ongoing attack that lasts more than a few hours. A worst case scenario in which state actors did seize all of the physical equipment could result in China only mining empty blocks and orphaning other blocks that did contain transactions, essentially halting all transaction confirmations on the network. Then it would become a game of either patiently waiting for them to give up or coordinating a code change that would make their hashing machines worthless.
Point being, any large-scale mining attack is going to be limited in its effectiveness for a variety of reasons and will be unlikely to disrupt network operations for more than a short period of time.

Looking Forward.
Matt Corallo designed Betterhash to further decentralize miner control away from pools. It looks like the first real implementation of this idea is occurring in Stratum V2.
Stratum V2 will also bring improvements with regard to template construction. It adds Betterhash-inspired job selection to give individual hashers more control.
Allowing miners to choose their own transaction sets moves some power from mining pools further downstream to the miners themselves, thereby increasing the censorship resistance of Bitcoin. This idea was originally put forth by Matt Corallo in BetterHash, and we felt it was very important to include in Stratum V2 as well because it has a meaningful impact on Bitcoin's decentralization.
Over the very long term I expect we will see semiconducter foundries outside of Asia begin producing more mining chips and countries with even cheaper power sources will continue to become more industrialized, thus providing more competition when miners are seeking out new locations to set up shop. China's mining dominance is unlikely to last; I expect that this theoretical attack will become less and less likely.

Why are GPUs Used for Mining?
Cryptocurrency mining is a term that is now familiar. But most often, people do not know precisely the process or tools used for crypto mining. Mining is a process of verifying transactions on the blockchain, or hashing blocks. To mine, CPUs, GPUs, or ASIC processing power is needed. Graphics Processing Units (GPU) has been used for years.
You may wonder, why are GPUs used for Mining? Well, the simple answer is that they are more competent than their counterparts CPUs and ASICs. However, to understand the need for the use of GPUs in crypto mining, we have to unveil some other factors.
How Much Data does Bitcoin mining Use.
The bitcoin protocol stipulates that only 21 million bitcoins will exist at some point. Just like gold, bitcoin miners work to bring these bitcoins out a few at a time. A miner runs what is known as a node. It is a powerful computer that keeps the bitcoin network running by running a bitcoin software.
To run a node, you download the bitcoin software for free and leave a particular port open. The one disadvantage is that it consumes a lot of energy and storage space. As of the end of June 2019, the size of the Bitcoin blockchain has reached approximately 226.6 gigabytes. Memory consumption per block runs in the range of 3 Terabytes and that is a lot of space consumption.
Each node spreads bitcoin transactions across the network. These mining nodes solve a complex mathematical puzzle. That is, each puzzle is solved by random guesses done by the hash function. The first miner to get the results makes an announcement and all the other miners start working on the next block. Miners currently receive 12.5 BTC as a reward for completing a block. If miners perform these functions, why are GPUs used for Mining?
What is the GPU?
Graphics Processing Unit (GPU) are cards made initially to generate and speed up images on electronic devices. GPUs were generally created for the gaming industry. GPUs are also computer chips that perform rapid mathematical calculations just to render images. However, the advent of cryptocurrency mining, made manufacturers alter their designs to suit miners. Some major companies in the GPU market include AMD, ARM, Intel, and NVIDIA.
The Function of GPUs in Cryptocurrency Mining.
When crypto-mining started in 2009, Central Processing Units (CPU) was the mining processor. However, it had its limits, and GPU-based Mining was introduced. A standard GPU can execute a processing speed of 3200 32-bit instructions per clock. Compared to the processing power of the CPU, this is a speed 8,000 times over.
Equally, GPUs are equipped with a large amount of Arithmetic Logic Units (ALU). These units are responsible for performing mathematical computations. GPUs can perform more calculations due to the ALUs, and this makes them have an improved output during Mining.
GPUs can carry out multiple tasks, and this is why miners prefer them. GPUs can be used to mine with different algorithms on chains. Also, you can quickly re-sell your GPU as they can be used for other purposes aside from Mining. For Mining, miners would have to set up multiple GPUs for mining rigs instead of a single unit. Also, the miners would have to attach these GPUs to existing infrastructure or computer as they are designed to act as supplements. You will also need enough SSD and RAM to enable the GPUs to function properly.
To set up a GPU rig , the miner has to connect multiple GPUs to a specially built CPU to increase the overall processing capacity. The miner attaches his GPUs to the CPU's motherboard that must not have any built-in graphics card. Like we said earlier, the miner needs enough RAM, SSD, and relevant wires. He also needs a support structure and a cooling system to build up his rig. Most miners build their platforms themselves, and so you may need some technical know-how. However, a would-be miner can watch tutorials on Youtube or order for a pre-built rig such as PandaMiner B5 plus.
Why is GPU Better Than CPU for Bitcoin mining.
Before the advent of GPUs for computing bitcoins algorithm, CPUs were used. However, GPU renders images more quickly than a CPU due to its parallel processing architecture. This is what enables the GPU to carry out multiple calculations at the same time. On the other hand, a single CPU does not have this capacity. You could achieve similar processing power using multicore processors. These processors can perform calculations side by side by combining more than one CPU onto the same chip.
Every computer has a CPU that can perform a single calculation faster than a GPU. CPUs are designed to handle basic computing tasks and operations. Basically, a CPU is created for task parallelism. On the other hand, the GPU is designed for data-parallelism.
The CPU has less arithmetic logical units and so when it comes to hash required proof of work, its performance is slow. However, you can still mine coins such as Hold Coin, Nexus, Zcash. GPU, on the other hand, can be used to mine coins such as Ethereum, Bitcoin Gold, Monero, Electroneum, and many others.
As compared to GPU mining and CPU mining, ASIC is more preferred. Its mining-hardware solves very complex algorithms. On the other hand, GPU and CPU mining hardware decode graphics algorithms and processor-based algorithms, respectively. However, the attraction GPU mining hardware holds is its offer of more hash power compared to CPU and low electricity cost compared to ASICs.
How Profitable is GPU mining?
Calculating the profitability of using a GPU mining rig has been made simple by NiceHash.com . The following are the earnings per day a miner will likely make using the following GPU mining rig.
GPU Earnings/Day AMD Radeon VII 0.00013100 BTC (1.35 USD) NVIDIA TITAN V 0.00011600 BTC (1.20 USD) NVIDIA RTX 2080 Ti 0.00010400 BTC (1.07 USD) AMD RX 5700 XT 8GB 0.00007800 BTC (0.80 USD) NVIDIA RTX 2080 0.00007700 BTC (0.79 USD)
On the other hand, the highest earnings per day for a CPU mining is $0.37 by the AMD CPU Ryzen 7 3700X. This goes to show how profitable GPU mining is as compared to CPU mining.
Pros of GPU mining.
GPUs are very efficient at complex computation. You can quickly get them. They are upgradable. Standard hardware. They have resalable value.
Cons of GPU mining.
High consumption of power. They are not as effective as ASICs. Compared to ASICs, GPUs are less powerful in overall efficiency. You may need large equipment for mining. They are restricted to mining certain coins.
A lot of coins still use the proof of work algorithm, and GPUs are still needed to mine these coins. However, compared to GPUs, ASICS a more efficient way of mining coins as they are faster. However, ASICs are very expensive and high maintenance. Moreover, GPUs give you excellent and ideal flexibility from mining a single coin. So, why are GPUs used for Mining? Simple, they are more efficient than CPUs and more cost-effective than ASICs.

Ethereum Mining Best GPUs - Top 5 Picks For Mining ETH.
Ethereum has been making headlines for a really long time now, and the hype is fueled by the upcoming launch of the much-awaited Ethereum 2.0 upgrade.
The enthusiasm around the upgrade which will take place by the end of the year and there are already various moves taking place ahead of it.
An essential piece of #Ethereum's Serenity upgrade, the Beacon Chain's deposit contract, is live. This begins a transition to #Eth2.@EthDotOrg Guide: https://t.co/PkKwLnXKS4 Launchpad: https://t.co/CFgFwAs46f Deposit Contract Address: 0x00000000219ab540356cBB839Cbe05303d7705Fa.
It's also important to note the fact that the price of the coin ETH has been surging as well, powered by the hype and the overall positive sentiment in the crypto market.
At the moment of writing this article, ETH is trading in the green, and the coin is priced at $491.35.
Mining Ethereum is a profitable activity these days, and in order to do this, you'll need specialized hardware - graphics processing unit (GPU).
It's also notable that Ethereum's devs originally planned for ETH to be mined on CPUs, but after a while, miners found that GPUs offer more hashing power.
In order to find the best GPU for mining ETH, you have to check out the ones with the highest hashing power; there are also GPUs that are using electric power as well.
Another important issue worth noting is that to find the most efficient GPU, the most important thing is a great balance between the power of the rig and the amount that you're willing to spend on the GPU and the electricity.
Here are the top five GPUs for mining Ethereum.
Radeon RX 5700 XT.
The Radeon RX 5700 XT with Triple Dissipation is the top card that ETH miners are using these days.
This unit can mine at around 60 Megahashes per card, and it uses about 68w/card - this comes at around $0.19/day. You can get it at about $400.
Nvidia GeForce GTX 1660 Ti.
Some people might prefer Nvidia and Nvidia GeForce GTX 1660 Ti is an amazing alternative to the RX 5700. This sits at 30.5 megahashes/card, at 68w. for this one, you will be paying $120 less.
You can also try older cards but with proved efficiency.
NVIDIA GeForce GTX 1080 Ti.
This was released three years ago, but it's still a great option when it comes to mining Ethereum. It's able to generate up to $58 monthly income due to the 21.63 MH/s hashrate. It also features great cooling tech.
You can find this at about $700.
AMD Radeon R9 295X2.
This was launched back in 2014, and AMD Radeon R9 295X2 can still be an interesting piece of ETH mining hardware.
With this one, you can expect a return of $580 on a yearly basis - it can grant a power cost per day of $1.44. this has a hash rate of 46.0 MH/s, and it's about $600.
NVIDIA RTX 2060 Super.
For mining ETH, NVIDIA RTX 2060 Super has the ability to generate more than $33.05 on a monthly basis, and it has a 35.49 MH/s hashrate.
You can find it at around $400.
Anyway, between Radeon and Nvidia most people are going with the first choice because this is comparable in power to Nvidia, but it's usually less pricey.
How to set up a bitcoin ASIC miner.
In the early days of Bitcoin mining, it used to be done using the CPU on your computer. Nowadays though as the amount of people mining has increased the difficulty of Bitcoin mining has also increased too. This high difficulty and hash rate has mostly been fueled by the introduction of ASIC mining chips. Bitcoin uses SHA-256 cryptographic hash function to secure the blocks and create the hash for each block. This encryption is what protects the transactions in the block from being altered.
Application-Specific Integrated Circuit.
ASICs allow miners to use hardware made specifically for Bitcoin or other SHA-256 algo coins. An ASIC has benefits over CPU, GPU and FPGAs due to being designed for one specific task. They are able to mine Bitcoin at a higher hash rate (speed of processing transactions) than CPUs, GPUs and FPGAs. В Several manufacturers produce their own ASIC chips and miners. For this part of the Bitcoin mining guide we will use the current top miner on the market the Bitmain AntMiner S9.
Bitcoin mining has gotten so high powered with the race to be the winner to solve a block that it has evolved into pooled mining where a group of miners want to have as much hash power as possible to get a share of the Bitcoin block reward. By combining your hash rate with that of many others you have a better chance of solving blocks (creating a block) and getting the block reward.
Bitcoin.com has launched it’s own mining pool with competitive pricing, which you can register for and begin pool mining today.
Bitcoin mining setup is simple.
The Bitmain S9 is composed of 189 ASIC chips. The total hash rate (mining speed) of the S9 is roughly 12 to 14 TH/s (terahashes per second). CPUs were only able to do a few MH/s (megahashes per second). As the S9 requires 1275 watts of power depending on your power type available you can either use twoВ 110v PSUs such as a Gold rated 1000 watt PSU and a 650 watt PSU to power the miner. If you are able to use 220v power and have the correct outlets or PDU (Power Distribution Unit) you can use special PSUs that are either made specifically for Bitcoin mining or even those made for servers. Connect the PSU/s to the S9 using PCIe cable connections on your PSU.
Once connected you will connect an ethernet cable to the miner itself. The next step is to turn on your PSU and the miner will power up from there. Next get on a computer or mobile device that is connected to the same network as the miner. You will need to enter in the miner's IP address. Since most miners now come with DHCP enabled you do not have to manually set the IP address, you just need to look at the IP table on your router or use a scanning tool.
A scanning tool like AngryIP allows you to scan every device on your network and see its IP address. When you run the scan you will see AntMiner as one of the devices. From there in your browser window you type in the miners address. This will take you to the first screen to login to the miner. In the case of the S9 the login box that comes up the username is root and the password is root. В Once you have logged in you will see the system overview. We suggest you go to the Admin tab first and change the password to one of your own choosing. Your next step is to go to the Miner Configuration tab. This is where you will add your information for the mining pool you will want to mine on.
You will need to enter in the stratum/IP address of your mining pool, then your worker name followed by password for your worker on the mining pool. Note: not all pools require a password, you can just put "123" if you want. Once you have saved your setting the miner will start mining on your pool. It can take from a couple minutes to up to an hour for your full hash rate to show up on your pool. Now you can go to the Miner Status page and you will see how your miner is performing and if the connection is live, temps, hash rate, etc. If you also go to your Bitcoin mining pool you can see your status.
S9 Resurrection: Higher Bitcoin Prices Allow Miners to Switch Outdated Mining Rigs Back On.
With bitcoin prices hovering over a certain handle, a great number of old ASIC mining rigs manufactured years ago are starting to become profitable again. Reports indicate that in China, where the average electricity cost is around $0.06 per kilowatt-hour (kWh), miners are starting to leverage old miners manufactured by Canaan, Bitmain, and others. Chinese bitcoin miners dealing with electronic component price increases have found outdated rigs like the Antminer S9 (10-16 TH/s) are now reaping profits again.
The price of bitcoin (BTC) is making it easier for cryptocurrency miners worldwide to obtain a profit, especially after the recent mining difficulty drop that slid over 16% downwards.
Additionally, BTC prices jumped from a closing price of $11,548 on October 13, 2020, and 30 days later on November 12, the price closed at a high of $16,305 per coin increasing 41.19%. Regional reports from China show that the high BTC prices between $12k to $16k have invoked Chinese miners to start leveraging old miners again.
In addition to the S9 models profiting, older machines made by Canaan Creative, Bitfury, GMO, Bitfily, Whatsminer, Halong, Ebang, and Pantech profit at higher bitcoin prices too. At the time of publication, the two 2018 series Avalonminers (921 and 841) are profiting between $0.21 to $0.59 per day if the miner is paying around $0.06 per kilowatt-hour (kWh).
Financial columnist, Vincent He, recently discussed the Bitmain S9 series (10-16 TH/s) and notes that the mining rig is pulling in profits for Chinese miners today. "The price increase of electronic components at the end of the year led to the improvement of S9's cost performance," the author noted on November 11.
Old mining rigs are not just pulling in a profit these days with BTC prices so high, the columnist notes. Vincent also says that numerous mining farms are located in desert regions where dust is high, and some are located in regions like Sichuan where humidity is higher than average.

How To Build A Mining Rig [Step By Step]|1:21:54

[Bitcoin]

These effects "shorten the life of the machines" and mining rigs like the "S9 has a better stability ratio because of its simple structure and relatively low computing power," according to the report. Estimates say at one time, the S9 miner (13 TH/s) was so widely used, these four-year-old machines powered around 70% of the BTC hashrate.
Roughly 11 Antminer S9 models manufactured by Bitmain that are anywhere between 1-4 years old, show profits between $0.10 to $0.59 at $0.06 per kilowatt-hour (kWh) using exchange rates for BTC on Friday, November 13, 2020.
BTC prices have dropped on Friday, November 13, and are a touch lower than the closing price the day prior. But data from Asicminervalue.com indicates that a number of older mining rigs produced by Canaan, Bitmain, and others are profiting at an electricity rate of $0.06 per kWh. Every single Bitmain Antminer S9 with a hashrate between 10 to 16 terahash per second (TH/s) profits today.
A number of older generation miners are being sold for $100-$800 depending on the model and hashrate. Marketplaces like Ebay and Craigslist have an abundant amount of miners for sale from manufacturers like Canaan, Bitmain, Microbt, Ebang, and many others.
Similarly, three old Avalonminers created by Canaan are profiting as well, except for the Avalonminer 821 and 741 series. In addition to the popular S9s and Avalonminers, outdated mining rigs created by Bitfury, GMO, Bitfily, Whatsminer, Halong, Ebang, Pantech, and other ASICs also show profits.
The older mining rigs are also seeing increased prices on second-markets in the U.S. and in Europe on marketplaces like Ebay and Craigslist.
For example, a Whatsminer M3 with 11.5 TH/s is selling on Ebay for $500, while old-school Antminer S9s are selling for $100-$800 per unit. Not too long ago, when BTC prices were lower and the difficulty was higher, outdated ASICs sold for $50-$250 per unit with a terahash output between 10-16 TH/s.
Vincent's report further notes that next-gen ASIC miners with an output of 70 to 100 TH/s have a greater number of computer boards than older models. The compact design of older mining rigs like the S9 series helps miners in China with warehouse space issues, as well as reducing power consumption the report details.
What do you think about older-generation ASICs like the Antminer S9 making a comeback? Let us know what you think about this subject in the comments section below.

Then we will look at The Best Bitcoin mining Rigs for Mining Bitcoins. We will also look at What Bitcoin mining Rig Hardware to Buy and Why. Find the Best ASIC Miner Hardware for Bitcoin CryptoCurrency rigs below.
Bitcoin mining Rig: What Are Bitcoin and CryptoCurrency Mining Rigs and The Best kinds of Bitcoin Rigs to Buy for Bitcoin and Crypto Mining. We Have all the Information Copyright:123rf.com/profile_pinglabel.
A mining rig is what you need to mine bitcoins with. It is just a term used for the entire setup needed to bitcoin mine and to do Cryptocurrency Mining. There are a few main components to the rig and several things to consider before setting up your Bitcoin mining rig.
You have read every theory there is to read about bitcoin and Bitcoin mining and have come to a conclusion that you want to join the community of bitcoin miners. Before you decide to go into Bitcoin mining, there are a few things you may want to take into consideration. First is the type of hardware mining rig to use and secondly is to know what the hardware mining rig offers, in terms of power consumption, hash rate, efficiency, and cost.
A Bitcoin mining rig uses a lot of electricity, and that means more bills, so it is important that you check the hardware's power rating, so you are able to know just how much extra you would be paying for electricity bills.
Your hardware is constantly solving mathematical calculations every second, so, hash rate basically means number of calculations per second, and its measured in mega-hashes per second (MH/sec), giga-hashes per second (GH/sec), tera-hashes per second (TH/sec) Basically, the bigger the hardware, the higher the hash rate and the more power consumed.
The best category of Bitcoin mining hardware to buy is the Application Specific Integrated Circuits (ASIC). The ASIC is just perfect for the job; it mines at great speed and consumes less power than GPU or FPGA miners.
ASIC mining hardware is expensive compared to GPUs and FPGAs, and that is because ASICs do a much better job than the others. ASICs use much less electricity, and they also solve Bitcoin mining blocks faster than the other categories of mining hardware.
With every rise in the price of bitcoin, there is a rise in the value of ASICs. With the rising demand for bitcoin, ASICs keep improving to keep up with the requirements of mining bitcoin efficiently, and quickly. Bitcoin and CryptoCurrency Mining can become like a gambling addiction and you can fixated on it, especially when you start to earn coins and make money when your bitcoin gambling investment pays off.
Here is a list of the best ASIC miners and their features that will give optimum performance:

NOTE: Daily Profit is estimations only, you must do your own calculations to end up with your daily profit rate. This is only a guide and not investment advice or what to expect. Your results may vary depending on your setup, and your software and electricity rates and the current rate of mining difficulty etc. Mine at your own risk, we are not responsible for your profits or losses. But, if Bitcoin ever does hit a million dollars like some guru's predict in 10 15 years or more once fully mined and then scarce, we will all be rich. But just don't count on it for sure as life is a gamble.
You are investing in Bitcoin mining and ASCI miners because you hope to get a return on investment, hence, it is important to also check a mining profitability calculator before purchasing the bitcoin miner. The profitability calculator calculates your ROI based on hash rate, current bitcoin price, power consumption, and equipment price. We all would like to have free bitcoin cryptocurrency but the fact is we have to mine it or invest in cryptocurrency.
Some other miners include Antminer U3, ASICMner BE Prisma, BTC Garden AM-V1, BFL Single 'SC', Avalon 2 etc.
Four graphic cards are connected to the motherboard via risers card Copyright: www.123rf.com/profile_andrewsht.
These are the graphics cards in your standard home computers which can also be used to mine cryptocurrency. The problem is that they are slower and less effective than asic miners and as the various cryptocurrencies continue to get mined the difficulty rating increases to mine that particular crypto further. You really need to use GPUs early on the ground floor beginning of a cryptocurrency to really see the benefits. Its not to say it cannot be done later but the as the difficulty increases you will need to keep updating your cards to get the maximum mining benefit.
That's the reason why graphics cards are increasing in price and becoming more scarce. People are continuing to upgrade their Graphics cards and adding additional cards to their existing computers to try and eek out more and more cryptocurrency as the mining difficulty increases.
The trick to using these is having multiple cards hooked up to a couple different motherboards. Just in case one motherboard goes down, you wont be out of business.
Best Places to Get your Bitcoin mining rigs are at Amazon and you can also try Ebay for new and used selection of all the newest and used Bitcoin mining rigs.

Bitcoin mining with gpu.
This website primary focus is all about GPU and CPU mining. And I've already listed most of the cards for mining here. But back then, the price of Bitcoin was $3,860. Right now, it's floating around $8,500, so I'm ready to analyze Bitcoin mining with GPU again.
How to pick the best GPU for Bitcoin mining.
As with any other method, Bitcoin mining with GPU is all about profitability. And to pick the most profitable GPU for mining, you need to pay attention to three things:
GPU mining hashrate(mining speed) power consumption(how much electricity it spends), and GPU price(this one should be self-explanatory)
GPU mining performance is usually measured in hashes per second(H/s) or Soles per second(Sol/s). However, telling you that an Nvidia GTX 1060 6GB has a hashrate of 24 MHash/s won't make much sense to you, especially if you're a beginner. Furthermore, different coins have different mining difficulty, so mining with same GPU will yield different amounts of different coins over the same time.
Like that's not complicated enough, mining the same amount of Bitcoin will give you different profit, depending on how much your GPU is spending power, as well how much you pay for that power.
And as you already learned- the GPU price must be added to the equation as well.
Graphics cards are usually the most expensive part of the mining rig(or PC), and after all they are the ones that perform mining. That's why picking the right GPUs for your mining operation is essential.
Luckily for you, picking the right GPU for mining in 2019 isn't as nearly complicated as you may think by now. Gathering the data and showing it in a table can make all the difference:
Newest Update on GPU mining performance(8/10/2020)
As you may notice, there are some differences compared to the previous table. Most importantly, the profitability is up. But besides that, we also have two newcomers in the cheaper range- Nvidia GTX 1660 and Nvidia GTX 1660Ti, both released in March 2019.
In February 2019, quite a few GPUs were unprofitable(spending more electricity than generating Bitcoin). Now the only unprofitable GPU is AMD Radeon R9 FURY, and only if your electricity costs are $0.10/KWH.
Now that we know how much we can spend, let's take a look at ROI(return on investment), so we can pick the best GPUs for mining in 2019. We will calculate ROI as price/earnings so we can see how many days it takes to pay off the GPU before you can start yielding the profit:
GPU Mining ROI(current Bitcoin price of $11,900) GPU GPU ROI(ZERO ELECTRICITY COST) GPU ROI($0.05/KWH ELECTRICITY COST) GPU ROI($0.10/KWH ELECTRICITY COST) AMD Radeon R9 380 79 days 103 days 150 days AMD Radeon R9 FURY 48 days 67 days 109 days Radeon™ RX 470 67 days 78 days 92 days Radeon™ RX 480 68 days 79 days 94 days Radeon™ RX 570 71 days 82 days 96 days Radeon™ RX 580 74 days 86 days 100 days Radeon™ RX Vega 56 201 days 243 days 303 days Radeon™ RX Vega 64 200 days 241 days 304 days GeForce GTX 1050 Ti 231 days 286 days 364 days GeForce GTX 1060 122 days 139 days 159 days GeForce GTX 1070 125 days 143 days 169 days GeForce GTX 1070ti 246 days 280 days 330 days GeForce GTX 1080 254 days 297 days 357 days GeForce GTX 1080ti 214 days 242 days 279 days GeForce RTX 2060 306 days 347 days 398 days GeForce RTX 2070 312 days 350 days 395 days GeForce RTX 2080 355 days 402 days 461 days GeForce RTX 2080 Ti 511 days 577 days 659 days Radeon™ RX 5700 205 days 225 days 249 days Radeon™ RX 5700 XT 217 days 238 days 263 days AMD Radeon™ Pro VII 605 days 660 days 722 days GeForce GTX 1660 244 days 283 days 336 days GeForce GTX 1660 Ti 252 days 276 days 307 days.

Before proceeding with top choices for 2020, I just want to remind you of something. The ROI is important only if you are looking to buy the best GPUs for your mining operation. If you already have them, the best thing you can do is just connect them, get the mining software and start mining. Since all GPUs are profitable at the moment(except the one I mentioned before), putting them into use really makes sense.
But if you are looking at buying some additional GPUs for mining, here are my picks:
Top GPU choices for mining in 2020.
The ROI data is implacable. The earnings winner is definitely AMD Radeon™ Pro VII, however it's very expensive and thus has a ROI of 605 - 722 days. Since the ROI is what defines our profitability, cards with the best ROI will be my top choices.
#1 - AMD Radeon R9 FURY(ROI: 48 - 109 days)
#2 - Radeon™ RX 470(ROI: 67 - 92 days)
#3 - Radeon™ RX 480(ROI: 68 - 94 days)
#4 - Radeon™ RX 570(ROI: 71 - 96 days)

Asic Bitcoin mining chip.
Best ASIC Miner in 2020.
Cryptocurrencies have been gaining momentum with every passing day, but now it's necessary to know how a cryptocurrency is mined. The mining process can be complicated, but you can understand the basics of crypto mining. Before delving deeper, let us understand ASIC (Application Specific Integrated Circuit), which is made for a specific use rather than used for general purposes.
What is ASIC Miner?
The ASIC miners come into the picture when it comes to mining with greater speed. ASIC miners are more developed and cost-effective when compared to traditional miners that use GPU, CPU, and other components. Bitcoin mining is effective when there is a benefit and there's high productivity at a low cost. The ASIC miners are generally designed to be co-worked with the mining rigs.
The advantage of ASIC mining is that they are efficient and can outperform a stack of GPUs any day. ASICs are 100 times faster and efficient than the traditional GPUs. Analysts predict that in the coming years, we can see the viability of the ASIC chips since its very energy efficient, and no alternative technology can replace within the energy frame.
There are two ways in which ASIC miners are manufactured- they can be either pre-manufactured to work with a respective application or manufactured and then integrated with customized applications. ASIC miner includes parts like software, ASIC chip, processors, and fans to keep the machine cool.
There are certain factors, based on which you choose the best ASIC miner in 2020:
#1 Hash Rate.
Hash Rate refers to the total number of complex calculations that can be solved by the computer every second. Hash rate enables to accelerate the chance of solving complex mathematical problems, which leads to winning block rewards. The miner who solves the computations accurately gets the block reward. Hence a high hash rate is high ASIC mining profitability.
#2 Energy Consumption.
The more powerful your mining hardware is, the more electricity you should expect to be consumed. So before purchasing, you must consider the consumption of electricity in watts. This will help you determine the viability of Bitcoin mining using the respective hardware. By using the hash rate and energy consumption, you can determine the number of hashes that can be mined for every watt of electricity.
#3 Price.
Don't always go after teh cheap hardware as it will rake in a few Bitcoins. Expensive Bitcoin mining hardware is fast, efficient, and unique. You need to aim for the miners with high value and quality instead of going for cheap equipment. Understand the ASIC miner value and ASIC mining calculation before opting for the miner.
Let's move on to the top 5 ASIC miners in 2020:
The Bitmain Antminer S5 may not be the latest model of the Antminer version, but it is quite efficient, powered by features like a power supply of 115 volts drawing around 560 Watts. Antminer is easily accomodating as it needs less power supply and power consumption. One unit produces 1 GH/s for every 0.51 watts consumed. It weighs around 2.5 Kgs. All these features make it the most powerful Bitcoin miner in the market.
Bitmain S7 model was introduced in 2015 and became quite popular as it consumes less power as compared to S5. The recommended power supply for using the S7 model is the 1600 Watt APW3- which is one of the best available in the market. It requires a minimum of 205 Volts to operate- its optimal power consumption makes it the most efficient. It weighs around 7.5 pounds. Ensure to put it in a cool environment in order to spend less energy.
Bitmain Antminer S9 is currently the best Bitcoin mining hardware available in the market with a hash rate of 14 TH/sec. This high hash rate is possible because of three circuit boards featuring around 189 chips. S9 can be used along with Antminer 1600 Watt power supply efficiently, and as while it consumes 300 watts more as compared to S7, it is 2X more efficient with around 0.1 Joules per GH.
Antminer T9 is considered as one of the best Bitcoin miners in 2020. It is a bit expensive as compared to others. T9 consumes around 1450 watts for 11.5 TH/s for batch 23, with an efficiency of 0.126 J/GH. But before deciding, note that the quality chips in S9 were being observed to have had lower quality leading to low stability. T9 miner got this problem fixed.
AvalonMiner 741 is the best when you are looking for an efficient Bitcoin miner at a budget-friendly price. This is a new addition by Cannan, as compared to the others. Avalon 741 provides a hash rate of around 7.3 TH/s and also has an air cooling system that enables 88 chips to function as a unit efficiently. It has an efficiency of 0.16 J/GH, which is one of the best as compared to other products, that too in this price range.

5 Popular ASIC Miners for Bitcoin mining in 2019.
Antminer S15 Antminer S9 Antminer R4 Canaan Avalon Miner 741 ASIC Ebit Miner e10 Things to remember when setting up ASIC To buy ASIC or not?
The strongest influence on the cryptocurrency market occurred in January 2018, when most digital assets collapsed in price. At that time people expected a drop in popularity for mining hardware, but nothing of the kind happened - the demand for ASICs, on the contrary, increased.
However, this is not astonishing, because the complexity of mining the most popular digital assets is always growing, and the miner is supposed to have powerful hardware. In this article, we are going to analyze the top 5 ASICs for Bitcoin mining.
Antminer S15.
Antminer S15 28 TH/S - the flagship model of all miners from Bitmain on 7-nm chips - is the most powerful of the new products released at the end of 2018. New miners have increased energy efficiency by only 30% compared to S9. In connection with the use of the new technical process, a more powerful increase in efficiency was expected. Managing miner is now divided into 2 modes: normal and economical. In economy mode, energy consumption will be reduced to 850 W, and the hashrate to 17 Th/s. In this scenario, the new ASIC for Bitcoin will consume 50 W per 1 Th.
Of the new changes, the S15 model has an additional power-saving mode and consumes almost 2 times less power, while the hashrate also drops almost 2 times.
Bitmain Antminer S9 is the most famous and common miner, designed for Bitcoin mining or other crypts using the SHA-256 algorithm. It was released in the summer of 2016 and has since been repeatedly "buried", but continues to enrich miners.
Among the most interesting characteristics, we note the hashrate of 13.5TH/s, the power consumption of 1,350W and two fans of 120 mm with a rotation speed of up to 6 thousand rpm. The device has 189 chips on a 16nm chip. For the future, you can take S9j, which already gives 14.5 terahash per second.
We can say that Bitmain Antminer S9 is still relevant in 2019. Of course, it no longer gives such a powerful profit, but its price has dropped at least three times, so most miners can afford it.
Given the payback period, as well as the prospects of SHA-256 algorithm and the demand for Bitcoin, this ASIC can still be considered as a budget entry to mining cryptocurrency.
ASIC miner Antminer R4 is a product of the well-known manufacturer Bitmain, featuring a high hashrate of up to 8.7 TX/s and relatively low power consumption of 845 watts. The device is positioned as ASIC for home use, due to the low noise level without loss of performance and efficiency. While looking for ASIC, special attention should be paid to the payback period and the price you will be guided by when choosing.
Due to a number of changes, the company's employees managed to reduce the noise level without a significant loss of hashrate. The first models appeared on the market by the end of the summer of 2016, but even today their use is relevant.
The price of R4 is relatively inexpensive. The cost starts at $1,560. It has high performance, and electricity consumption is insignificant compared to other analogs.
Canaan Avalon Miner 741.
Most recently, Canaan Creative presented the miner Avalon 741 - its new ASIC for mining Bitcoin. The successor to the 721st model was to become a direct competitor to S9 from Bitmain. It is quite noisy and requires lots of electricity, but at the same time very productive. ASIC was not lost among competitors even six months later.
Avalon supports 741 to 40 TH/S in series. To achieve it, you need immediately to turn on 7 machines. In single mode, 7+ TH/S works out. The increase, compared with the 721st, was a little more than one terrahash due to:
88 A3212 chips made on 16 nm technology versus 72 of the previous model New cooling system More power lines.
ASIC Ebit Miner e10.
The main characteristic of this equipment is high hashrate. It is 18TH/sec. High efficiency is ensured by functioning on 14nm DW1227 chips. Moreover, there is an independent cooling radiator with increased heat dissipation. It is also worth noting the increased degree of reliability of the heat sink.
The miner has the following benefits:
Low failure rate Powerful fan Superb aluminum housing Availability of auto cluster management independent of each other The ability to connect more pools and ease of ASIC configuration.
Power - 1.62 kilowatt Hashrate - 18 Tx/s 3 years official warranty from the company Operating on the SHA-256 algorithm.
Things to remember when setting up ASIC.
When setting up an ASIC it is worth paying attention to the following factors:
Ensure that no moisture gets into the ASIC. The power of the power supply should be sufficient for stable operation; when overclocking, take the power supplies with a margin of 25-40% power. Clean, blow and replace radiators at least once every few months. Watch for errors and the appearance of an "X", indicating the beginning of problems with the equipment. Diagnostics will help identify damage to the power supply circuit and the loss of chips on the board. Analyze your hashrate level. Its reduction indicates that there is not enough power going to the chip.
To buy ASIC or not?
The situation in the cryptocurrency market is still far from optimal. The rates of most currencies retain volatility and commitment to speculative fluctuations. Due to the long bearish trend, lots of people have sold their hardware. However, in the long-term perspective, Bitcoin mining at ASICs remains a stable source of passive income. As the complexity of the network increases, the remuneration may decrease, but don't let that frighten you, because great risks promise great benefits.

Requirements to proceed with mining:
One way that you can get started mining bitcoin for free is to try to mine with a low-end PC. This will be expensive initially but it will save you a lot of money over time as you add more CPUs and GPUs to your mining rig. To get started with this method, you should try to spend no more than half of your own money. That way, if your computer does well, you can add a few hundred dollars to your budget. When you add more computing power to your mining rig, it is much more profitable. Of course, if you are spending more than half of your own money, you will want to replace it with some of your "other" funds. So, if your computer does well, you may want to try a new PC. One popular method is to use a CPU to mine. A PC will convert a block of transactions to send back to you. It's a CPU based method. To do this, your computer must connect to the network. I recommend buying a $20 USB adapter to make it easy. You simply plug the adapter into one of your USB ports and it will do the work for you.
Choosing what to mine:
Once you're connected to the network, your computer will process transactions. When it does, it sends the results to a remote server. Here you can see your block of transactions. Now, here's how to use the information that you've mined out of the blockchain to purchase items in your wallet. Once you have purchased something, it will display in your wallet. The items that are usually available are Bitcoins, Litecoins, Dogecoins, and Namecoins. You have to make sure that you've downloaded your wallet onto your computer first. Okay, let me tell you how to mine bitcoin on your laptop. You can either do it yourself or use a company that will provide you with access to miners.

If you're looking to start Bitcoin mining on a laptop these days, it's a bit different then laptop mining for Bitcoin way back in 2009 when Bitcoin's core developer Satoshi Nakamoto was first pioneering Bitcoin mining.
Currently, cryptocurrency mining is becoming more popular, and with future advancements in laptop's hardware, the question to mine Bitcoin on a laptop resurfaces.
Can I mine Bitcoin with a laptop? Yes, in 2020 there currently is mining software that allows users to mine for Bitcoin on laptops. However, mining directly on Bitcoin's network with a laptop will almost certainly produce unprofitable mining results. If you want to earn any Bitcoin at all with a computer these days, you'll have to use additional laptop Bitcoin mining software.
In the beginning, when the first Bitcoin miners evolved, BTC mining on a laptop or CPU mining as they call it was the only way you could mine for bitcoins at the time. At that time there was not a specific mining laptop because the network was small which let anyone with any type of laptop participate.
This golden window of opportunity was short-lived and was replaced with GPU mining in 2010 when a code was released that enabled GPU mining which made central processing units or (CPU), financially unfeasible to mine Bitcoin.
Over the last eight years mining for Bitcoin has primarily evolved into the use of ASIC chipsets engineered explicitly for Bitcoin mining. If you're going to get any Bitcoins with a laptop or GPU these days, you're going to need to go about it differently.
In this guide, we reveal several ways you can start earning Bitcoin with a mining software for your laptop, PC, and even MacBook if you want too. Whether it's a gaming PC or a computer for regular use, this will apply to both types of devices.
How To Mine Bitcoin On My Laptop Or PC.
Back when Bitcoin mining first started you could download a client and point your laptop to hashing directly on Bitcoin's network to solve blocks. Over the years the difficulty on Bitcoins network has grown so significant that it would be almost virtually impossible to have any success solving blocks successfully with anything other than an ASIC Antminer.
So how is it that you can still mine on a laptop these days and earn bitcoin?

Well, there a couple of ways we can go about this with NiceHash being the most popular of them all. However if for some reason you wanting to pursue laptop mining on a Macbook then refer to instructions at the bottom of the page.
NiceHash is essentially a marketplace for buying and selling your hash-power.
Buyers looking into mining low difficulty cryptocurrencies without physically operating or owning mining hardware can bid on and rent computing power from sellers inside NiceHashe's platform with a form of payment in Bitcoin. Checkout the NiceHash marketplace here to sign up.
All that is needed for sellers to participate in earning Bitcoin is to download and set up NiceHashes mining software on their laptop mining device.
Profitability for sellers can vary depending on hardware and the demand for hash-power from buyers.
Back late 2017 in Bitcoin's peak the demand was so high that a lot of miners decided to sell their hash power as it was more profitability at the time than actually mining cryptocurrencies like Ethereum.
NiceHash has been around since 2014, and I've used them a lot personally without any significant issues. They did have a wallet breach in 2017 that affected a lot of miners, especially those who mined to NiceHashe's internal wallet.
SIDENOTE: The safest way to protect your mined coins with NiceHash is to create an external wallet with Coinbase. Be sure to use the Coinbase Bitcoin wallet address when its time to set NiceHash up.
Once you get a Coinbase wallet set up then head on over to NiceHash so you can download the correct mining software.
If you have an AMD or Nvidia graphics card be sure to select the correct download.
After you complete the download, you'll want to run the mining software for the first time by clicking on the executable file inside the download folder.
Give the miner a few minutes to boot up and have a copy of your Bitcoin wallet address from Coinbase ready to be pasted into the mining software when prompted under the wallets tab.
You'll then need to name your miner something like Rig1 under the name tab, save it, and then hit start.
The miner will then run a series of benchmarks to test your laptop's hardware across several algorithms and can take up to 2 hours depending on your machine's hardware. Once finished the miner will start running, and you should begin to see the estimated payouts calculated on the user interface.
One of the significant advantages of using NiceHash over any other option is the fact your profits can be much higher when the demand from the buyer increases. With that mentioned its also one of its disadvantages as it can be less profitable if the demand from buyers isn't there.
Up next on our list of laptop Bitcoin mining software is Honeyminer. Unlike NiceHash where people have to rent your mining computing power to earn any Bitcoin. Honeyminer's laptop mining software has your hardware mining the most profitable crypto coins directly into an exchange where they are cashed out in Bitcoin and then paid out to the miner.
Setup for Honeyminer is slightly different as you have to go to their website and download the mining software and install it on your PC device first. Once installed its asks you to set up a username and password which you'll need later to withdraw earned Bitcoin.
From here its pretty simple, if you have a gaming laptop with a high-end GPU, then you'll have the option to enable your device for GPU mining as well. After that, you'll be prompted to the next screen and have the choice to turn the miner on or off and other configuration options like running only when at idle speeds.
Back at Honeyminer's website you can now log in with the same username and password used in setting up the miner and go inside your dashboard. Be sure to click on the money tab and then the withdraw tab and paste in your Bitcoin Coinbase wallet address to receive Bitcoin payouts.
Now that we've discussed these two mining software's it wouldn't be fair not to mention both come with some small convenience fees.
With Honeyminer fees for one GPU are 8% and 2.5% for two or more and NiceHash has a flat fee of 5%.
Both have advantages based on demand and market conditions, so it's tough to say which one is better over the other. In the end, you'll have to try them both and compare them with your laptop.
However, if these both haven't got you excited enough to start Bitcoin mining on your laptop, or maybe the fees turn you off the idea, then Option C of my secret weapon laptop mining software is for you.
Awesome Miner is another auto profit switching and auto currency converting miner. Perfect for anyone who wants to be sure their laptop always mines the most profitable coin no matters what without the fees.
