AMD Blockchain Driver - driver for AMD Radeon GPUs (Download)
AMD Blockchain Driver - Mining Driver for Radeon.
It's not a secret for all of us that AMD Radeon video cards are very popular among cryptocurrency miners, especially for them the Radeon Technologies Group programmers have prepared a new AMD Blockchain Drivers driver package. Which aims to improve farm performance based on AMD Radeon GPUs.
OS Support : Windows 7 and Windows 10.
Supports most current AMD graphics cards, starting with the Radeon HD 7700 line.
The new version of the driver is in beta status. It is also worth noting that it is not intended for graphics or game loads. And provided by the manufacturer "as is."
In the future, the company is not going to optimize or correct errors. This, in turn, makes it the first and last driver package for mining systems. Regarding specific improvements over conventional Radeon Crimson ReLive driver packages. That, as noted, the new release solves the problem of reducing the efficiency of Ethereum mining.

Best Bitcoin mining Tools For Windows, Mac, And Linux For 2020.
If you are reading this article, it means you heard about Bitcoin and Blockchain technologies. You may see everyone talking about Bitcoin online and no person who is clearly aware of it in nearby you.
Bitcoin is a decentralized virtual currency created from the Blockchain method. It uses blocks to generate a transaction virtually and it stores on every computer connected to Blockchain. It means if you installed a mining tool on your PC, then you are connected to the Blockchain network.
So the question comes in mind. How a miner generates a piece of Bitcoin when he contributes his/her computational power to the Blockchain network.
All we know Bitcoin works on a Blockchain technology that works as a peer-to-peer network. It is an immutable chain of transactions as it uses a strict verification process, and cryptography techniques to make it secure. If a miner entered into the pool of Blockchain network, he/she will contribute the computer power to solve the transaction algorithms to verify a transaction on the network.
Best Mining Tools For Windows, Mac, And Linux.
Multiminer : Best for beginners EasyMiner : Easy to use GUI CGMiner : Best for ease of use MinePeon : Hassle-free use Hashr8 : Best for Linux users.
Here how it works:
Person A sent 1BTC to Person B on a Blockchain, the entire network of the public Blockchain can access the transaction and verify the process the computational power is required to solve the complex algorithm. When you solve a transaction algorithm, you will be rewarded by the chunks of Bitcoin depends on the transaction value.
Once your system creates a successful hash of a transaction, you will receive some reward in the form of Bitcoin. However, you should also take into account that, you need a great computational power to generate a good amount of reward.
Considering the present situation, the mining process can be done in two ways. One is Cloud mining and personal or traditional mining.
In Cloud mining, people don't need personal hardware for the mining of Bitcoins. The hardware is located in a remote datacenter managed by the professionals who give permission to use the allocated hardware resources by paying the monthly rent.
What is traditional mining?
Traditional mining or personal mining is a common process of generating Bitcoins by contributing his/her own computing power to solve the transactional algorithms. It involves your personal PC or laptop with mining software.
Once you select the type mining process for Bitcoin mining, here we suggest the best cloud and traditional mining software for Windows, Mac, and Linux.
Best Bitcoin mining Tools For 2020.
1. Multiminer.
Multiminer is a user-friendly mining tool if you are a beginner. Cryptocurrency is a highly volatile platform and you need a stable working miner to enter into the mining. Multiminer has many advantages, it has GUI for easy understanding the Setup and process unlike the command line based miners.
The best part of the tool is switching between cryptos and also the mining devices. For example, you can switch between ASIC's to FPGA's within the program and also switching possible between Bitcoin to other cryptos like Etherium, Litton etc.
Also, it is an open-source project and compatible with many mining devices. The application is available for Windows, macOS, and Linux platforms.
EasyMiner is a graphically rich and easy to understand mining tool. The service supports a wide variety of cryptocurrencies to mine. The program supports cudaminer, ccminer, cgminer, minerd, and ASIC mining support for Bitcoin. The solo mode in the program lets the user choose a pool of their own to mine their favourite coin. It has military-grade security to avoid hacking and stealing of the cryptocurrencies. Also, the program is fully optimised for both x86 and 64bit machines to get maximum support.
3. CGMiner.
CGMiner is a C based miner available for Windows, Mac and Linux. You just need a small configuration setup to install the CGMiner on your computer. Once you configure the conf file, you are all set to mine the coins. Double-clicking on the cgminer.exe will open the program and the rest of the mining process is taken care of by the tool. CGMiner is a good mining tool but it needs some technical knowledge to initiate the process. If you are amateur on the technical side, go for the Multiminer to start the coin mining process.
4. MinePeon.
MinePeon is a powerful miner available for Linux machines. It is a powerful mining software designed only for clean mining purpose. Just install it on your Linux machine and do usual work. It will mine for you in the background and generate small revenue for you. It is a completely secured tool which is tested before launching the stable versions.
5. Hashr8.
Hashr8 is a popular mining tool available for Linux users. It is a customizable mining software for Linux users. It is designed for everyone and all types of miners from hobbyists to enterprise solutions.
These are the five mining tools suitable for everyone to start their crypto mining journey. There are many more tools available online for various platforms. The above tools are tested by me personally and I feel they worth mentioning in the list.
Let us know your valuable feedback in the comment section below.

Bitcoin mining pool share.
Bitcoin mining pools are a way for Bitcoin miners to pool their resources together and share their hashing power while splitting the reward equally according to the amount of shares they contributed to solving a block.
A "share" is awarded to members of the Bitcoin mining pool who present a valid proof of work that their Bitcoin miner solved. Bitcoin mining in pools began when the difficulty for mining increased to the point where it could take years for slower miners to generate a block.
The solution to this problem was for miners to pool their resources so they could generate blocks quicker and therefore receive a portion of the Bitcoin block reward on a consistent basis, rather than randomly once every few years.
Sometimes you may want to mine a more profitable altcoin like MWC which is superior for scalability, privacy, anonymity and fungibility.
When segwit is activated, you will want to be able to mine and relay segwit-style blocks. The following mining software has been upgraded to support segwit.
Full nodes: Bitcoin Core 0.14.1 Bitcoin Knots 0.14.1 Btcd* Mining software: BFGMiner* CGMiner libblkmaker* Pool software: ckpool Eloipool Stratum-Mining* Relay software: Bitcoin FIBRE.
Please note that software that supports the GetBlockTemplate (GBT) RPC must be upgraded to support the BIP9 and BIP145 changes to GBT. All the programs linked above that support GBT have been upgraded.
Segwit is already activated and enforced on testnet, so you may find it useful to test your infrastructure upgrade by mining with some small amount of hashrate on testnet. Alternatively, Bitcoin Core 0.13.1's regression test mode (regtest) also supports segwit by default.
There are many good Bitcoin mining pools to choose from. Although it's tempting to pick the most popular one, it's better for the health of the network to mine with smaller pools so as to avoid potentially harmful concentration of hashing power.

The hash rate distribution is best when split among more Bitcoin mining pools.

Bitcoin mining Pool Options.
For a fully decentralized pool, we highly recommend p2pool and Multipool.us.
The following pools are believed to be currently fully validating blocks with Bitcoin Core 0.11 or later:
BTCC : BTCC is a Bitcoin exchange, wallet, and mining pool located in China. Its mining pool currently controls around 15% of the network hash rate.
Slush Pool : Slush Pool is run by Satoshi Labs, a Bitcoin company based in the Czech Republic. Slush Pool was the first mining pool and maintains around 7% of the network hash rate.
Antpool : [WARNING] - Bitmain operates Antpool and some consider them to be a malicious actor in the Bitcoin ECOSystem because of the AntBleed scandal where they were intentionally including malware within mining equipment they sell. In a corporate communication, Bitmain claimed this was a feature and not a bug. This malware would enable Bitmain to remotely shut down equipment of customers or competitors thus increasing their own profitability. Additionally, such behavior could pose a risk to the entire Bitcoin network.
Eligius : Eligius was one of the first Bitcoin mining pools and was founded by Luke Dashjr, a Bitcoin Core developer. Today, the pool controls just under 1% of the network hash rate.
BitMinter : BitMinter, once one of the largest Bitcoin mining pools, now controls less than 1% of the network hash rate.
Kano CKPool : Kano CKPool was founded in 2014 and currently has around 3% of the network hash rate under its control.
F2Pool : F2Pool is the second largest Bitcoin mining pool, with around 25% of the network hash rate. Its user interface is in Chinese, making it difficult for English speakers to join.
BW Pool : BW Pool controls around 7% of the network hash rate. Like F2Pool, its user interface is in Chinese, making it difficult for English speakers to join.
Bitfury : Although seen publically in block explorers and hash rate charts, BitFury is a private mining pool and cannot be joined.
Bitcoin mining Pool Payment Methods.
Calculating your share of the bitcoins mined can be complex. In an ongoing effort to come up with the fairest method and prevent gaming of the system, many calculation schemes have been invented. The two most popular types are PPS and DGM. PPS, or 'pay per share' shifts the risk to the mining pool while they guarantee payment for every share you contribute.
PPS payment schemes require a very large reserve of 10,000 BTC in order to ensure they have the means of enduring a streak of bad luck. For this reason, most Bitcoin mining pools no longer support it.
One of the few remaining PPS pools is EclipseMC. DGM is a popular payment scheme because it offers a nice balance between short round and long round blocks. However, end users must wait for full round confirmations long after the blocks are processed.
PPS : The Pay-per-Share (PPS) approach offers an instant, guaranteed payout for each share that is solved by a miner. Miners are paid out from the pools existing balance and can withdraw their payout immediately. This model allows for the least possible variance in payment for miners while also transferring much of the risk to the pool's operator.
PROP : The Proportional approach offers a proportional distribution of the reward when a block is found amongst all workers, based off of the number of shares they have each found.
PPLNS : The Pay Per Last N Shares (PPLN) approach is similar to the proportional method, but instead of counting the number of shares in the round, it instead looks at the last N shares, no matter the boundaries of the round.
DGM : The Double Geometric Method (DGM) is a hybrid approach that enables the operator to absorb some of the risk. The operator receives a portion of payouts during short rounds and returns it during longer rounds to normalize payments.
SMPPS : The Shared Maximum Pay Per Share (SMPPS) uses a similar approach to PPS but never pays more than the Bitcoin mining pool has earned.
ESMPPS : The Equalized Shared Maximum Pay Per Share (ESMPPS) is similar to SMPPS, but distributes payments equally among all miners in the Bitcoin mining pool.
RSMPPS : The Recent Shared Maximum Pay Per Share (RSMPPS) is also similar to SMPPS, but the system prioritizes the most recent Bitcoin miners first.
CPPSRB : The Capped Pay Per Share with Recent Backpay uses a Maximum Pay Per Share (MPPS) reward system that will pay Bitcoin miners as much as possible using the income from finding blocks, but will never go bankrupt.
BPM : Bitcoin Pooled mining (BPM), also known as "Slush's pool", uses a system where older shares from the beginning of a block round are given less weight than more recent shares. This reduces the ability to cheat the mining pool system by switching pools during a round.
POT : The Pay on Target (POT) approach is a high variance PPS that pays out in accordance with the difficulty of work returned to the pool by a miner, rather than the difficulty of work done by the pool itself.
SCORE : The SCORE based approach uses a system whereby a proportional reward is distributed and weighed by the time the work was submitted. This process makes later shares worth more than earlier shares and scored by time, thus rewards are calculated in proportion to the scores and not shares submitted.
ELIGIUS : Eligius was designed by Luke Jr., creator of BFGMiner, to incorporate the strengths of PPS and BPM pools, as miners submit proofs-of-work to earn shares and the pool pays out immediately. When the block rewards are distributed, they are divided equally among all shares since the last valid block and the shares contributed to stale blocks are cycled into the next block's shares. Rewards are only paid out if a miner earns at least. 67108864 and if the amount owed is less than that it will be rolled over to the next block until the limit is achieved. However, if a Bitcoin miner does not submit a share for over a period of a week, then the pool will send any remaining balance, regardless of its size.
Triplemining : Triplemining brings together medium-sized pools with no fees and redistributes 1% of every block found, which allows your share to grow faster than any other Bitcoin mining pool approach. The administrators of these Bitcoin mining pools use some of the Bitcoins generated when a block is found to add to a jackpot that is triggered and paid out to the member of the pool who found the block. In this way, everyone in the pool has a better chance to make additional Bitcoins, regardless of their processing power.

How to quickly check your mining speed?
Is there some website that provides some webminer or other way for a person to check their mining speed without actually joining any pool or doing solo mining? Alternatively, are there some miners that can be pre-configured to perform mining on a specific pool with given credentials?

Bitcoin

Or to put it in another way, if I wanted to simplify the process of checking a mining speed of a given computer for someone with minimal knowledge of what Bitcoin is, what websites or software should I use?

5. Now you have to change your wallet address in the file and save it.
6. now you have to run the following command to make it executable.
7. Now just run the run.sh and your CPU mining will get stated.
Congratulations on completing all the steps Happy Mining :)
Ethereum GPU cryptocurrency mining with Ubuntu 20.04 / AMD OpenCL Compute in Linux.
Jose Ignacio Martinez.
Aug 25 · 5 min read.
Howdy! :) I just wanted to write my own story of frustration and success while doing Ethereum GPU cryptocurrency mining. I've been doing this as a hobby for a few years now, and I think it's time to give some advice back to the community.
I'll be covering most of the process from scratch, including:
Software involved (OS, GPU drivers, Ethereum wallet and mining clients) Hardware needed (AMD Radeon RX4XX/5XX, Vega 56/64, VII, 5XXX, for Ethereum ≥4GB)
Most of the tutorials out there are pretty old and do not cover updated software, so lets start describing what I already did without much luck. For the fun part, jump straight into "Hands on".
Windows 10 is a good option to start due you are probably familiar with it, and also software and drivers are quite easy to install/use, however is not open-source, not secure and could be quite unstable for long-term mining (yeah, thanks windows update). So instead of covering Windows, ill be describing how to do this with an open-source operative system (yeah, thanks Linux).
Initially I tested the good old Ubuntu 16.04, with several AMDGPU-PRO compatible drivers ( 17.40-483984, 17.40-492261 and 18.40-673869 ). None of those worked properly with old+new cards connected. I mean for my old Radeon RX 570 only, worked like a charm, but was very buggy along a RX 580/590 and 5700 XT. Including but not limited to poor hashrate, full fans speed, overheating, video crash, "drm failed testing IB on ring" errors, black screens and reboots. Ubuntu 18.04 was fine with amdgpu-pro-18.40-673869 and RX 570, but wont even boot the ISO with newer cards in place. So with not much alternative, I gave the latest Ubuntu release a try. According to the official AMD support driver website is supported, so why not?
Hands on.
So this will be the first step, download Ubuntu 20.04.01 ISO and deploy the ISO file into a USB drive, DVD, memory card, anything that holds the ISO and can be booted by your motherboard. If you are using a USB device, I recommend using Rufus create the boot drive, is simple and effective.
My current mining rig is not dedicated, I use it for work and gaming, also I don't like dual-boot for this purpose, so my setup use a USB drive to host the OS. Any flash drive≥2GB should work, of course you can use dual-boot, another hard drive or any other storage, Linux is very flexible and tolerant. Now install Ubuntu Server, nothing special about the setup, I avoided all the extra software and the only optional component installed was the SSH server for remote access. Reboot and login.
Some people will recommend to do a full apt update && apt upgrade , I don't. Any change in the kernel may broke the drivers setup and will be very hard to go back to the original state. Also during the OS install, if a internet connection is configured, security updates will apply on-the-fly safely.
Drivers.
At this point you will need the AMD GPU PRO driver, you could download from AMD support website (make sure is the Linux driver for Ubuntu 20.04.1) and them move it into Ubuntu, or download directly from your console using the following command.
Now we need to extract the file and install the drivers, note that we are installing legacy drivers with the rocm component and in headless mode.
*** ROCm is the open-compute platform, we may not needed but I recommend have it just in case, many tools related with cryptomining use it.
Once installation has completed, reboot and login again.
Mining clients.
I will assume at this point that you are aware that there's endless cryptocurrencies available to mine using GPUs, therefor there's many mining clients; Close and open-source, multi-coins, dual miners, with and without a developer fee (devfee). Is not easy to pick your first GPU mining client, but in simplification I'll explain how to use two miner clients that I use to mine Ethereum.
The first one, EthMiner is the official open-source mining client without any devfee and the second one is PhoenixMiner, a more advanced mining client that have devfee of 0.65%. This means that every 90 minutes the miner will mine for its developers, for 35 seconds. Why two clients? Well, it's good to have an alternative, compare performance, and also PhoenixMiner allow us to mine Ethereum with 4GB GDDR video cards, while this is not possible now with EthMiner due DAG size.
Download and install clients, create scripts and edit them could be very challenging for most people, specially from a terminal. So, for easy to use and also move a bit faster, I created a public repository with the clients, tools and the scripts to run your mine operation in no time. To be able to clone and use this repository, make sure you have git installed first, then clone it locally with the second command.
Now the the repository has been cloned, let's get into and test our recently installed drivers.
If everything goes as planned you should see the DAG generation and the miner slowly starting to work, also your video card(s) should soon start speeding they fans. You can interrupt this with Ctrl+C .



Bitcoin

Ethereum pool and wallet.
Now that we have the hardware (GPUs) and software (mining clients) working together, we need to move to the wallet and pool. This is not specifically for Ethereum, every cryptocurrency miner require this information. The wallet is the final destination of your profit (cryptocoins) and the pool is a massive amount of workers (miners) working together to resolve the blockchain problems.
To create a wallet I recommend skip using website or 3rd parties, they are not safe. My choice for Ethereum is create the wallet direct into the blockchain using Geth, the Ethereum node client. You can follow up the instructions here. Make sure to store the private key and password in a safe place, this will allow you to use or move your cryptocoins later. One thing that is public is your wallet, is a string that looks like this (starts with 0x):
The pool act as a proxy, helping many miners to work together against the problem, to have a reward even if you mining power (hashrate) is very small. I've been mining with Nanopool for many years now, is very stable and have worldwide servers. Another nice things about pools, with your address you will be able to see the current workers and they hashrate and rewards, they do payments to wallets every 0.1 ethereum collected.
Mine using your wallet.
Now you can mine on any pool with your wallet, so is time to edit the script and replace your wallet, this could be done with any text editor or forking the repository and changing the address (and pool if you are not using Nanopool).

0.5A) Cooling fan Heat sinks OPTIONAL: Raspberry Pi to control the miner(s)
Powered USB Hub.
Cooling.
A12V DC CPU fan can also do the job, and most likely provide better cooling performance as well. However, a CPU fan requires a separate 12V DC power supply. While practically it can run off from 5V DC, the airflow will be severely limited.
I have seen many people using a fan such as this one, I assume it does a nice job.
Personal Experience.
I have decided to cover the top of my Block Erupter in heat sinks to increase heat transfer to the environment. I have ordered some small Copper heat sinks from eBay with some thermal paste sticker on the back for easy application. I will mount these on the front side of my miner and then direct a small USB fan on it as well. I hope to keep the temperature of the miner as low as possible using this method.
USB fan (source:Amazon.com)
Update: Unfortunately, my heat sinks didn't arrive from eBay so I have decided to give up this plan. Instead I have found a small USB fan I bought previously that I can use here. (see image on the left) The fan produces quite a strong air flow so I have decided to have a go at it.
I have removed the outer case so I am left with the inside only that allows me to better direct the airflow over the Block Erupter. It is a little noisy, but I am running it in the basement so it doesn't bother anyone.
This fan keeps the ASIC miner at room temperature without any problem, it doesn't heat anywhere as much as without the fan.
As a footnote I noticed that when operating the miner from a USB port on my laptop it heats up much faster than when powering it via an USB hub. Also I noticed that (at least when plugged into my laptop) the miner heats up even when I am not mining with it, LED lighting.
300 MH/s one will not get rich, it is just enough to make up for the price of electricity and the initial investment.
Following the success of Bitcoin many different peer-to-peer currencies have appeared on the internet. One of these was Litecoin. And even though it was designed by following the bASIC principles behind Bitcoin, it has some major differences.
This guide will show a likeliness to Bitcoin BASICs and Ubuntu 12.04 simply because the similarities in the client and mining software and the currency in general.

Litecoin network uses the scrypt algorithm that was specially designed to take longer time to compute, hence hashing rates are lower than in the Bitcoin network. However, since a new block is generated - on average - every 2.5 minutes (compared to 10 minutes in the Bitcoin), there will be 4 times as much coins in existence, summing in 84 million.
Another aim for Litecoin was to avoid concurrence to Bitcoin. While FPGAs and ASICs are providing the majority of the Bitcoin network's hashing power, these are not usable for Litecoin mining (or at least not yet). Litecoin mining is economically viable on available, consumer hardware. As the global hashing rate is slower, there will be no handful of individuals "dominating" the network with extremely powerful devices (to be seen in the future). However, there is still concurrence, as if one has a GPU, a decision has to be made whether to mine BTC or LTC.
Installing the Litecoin Client.
It has to be noted that Litecoin has also 2 client versions, litecoind and litecoin-qt . Litecoind is the "litecoin daemon, a terminal version, whereas litecoin-qt is the qt4, GUI version of the client software. Unless you know what you are doing, it is recommended to use the GUI version of the client, litecoin-qt.
Package dependencies have to be satisfied. Run the following command to install necessary packages,
If you have the Bitcoin client installed, you probably already have all packages.
Download the latest client software Unpack the downloaded file to anywhere on your computer Navigate to the unpacked directory/bin/## Launch the executable file "litecoin-qt"
This will launch the Litecoin client.
Run the following commands in a terminal window to install the client,
wget https://github.com/downloads/litecoin-project/litecoin/litecoin-0.6.3c-linux.tar.gz tar xzvf litecoin-0.6.3c-linux.tar.gz cd litecoin-0.6.3c-linux/## ./litecoin-qt.
After running the executable file, a directory ".litecoin" will be created in your home directory. /Home/$USER/.litecoin contains your blockchain and wallet.dat file. (You can press Ctrl+H to view hidden files)
The Litecoin client is nicely integrated into the Ubuntu menu bar, originally an issue with older Bitcoin clients.
The generation of new blocks is done by "mining" that is the investing of computational power. As the Litecoin was designed to be unfavourable for specific mining hardware (FPGA & ASIC), mining is currently only done using CPUs, but mainly GPUs.
There are back end software, actually doing the mining and there is a GUI front end, that allows quick and easy configuration.
cgminer --scrypt reaper miner pooler cpumineer.
Cgminer is the same miner that is used for mining Bitcoins, but with the argument "--scrypt" it can be used for mining Litecoins. Uses GPU and requires AMD APP SDK on ATI/AMD cards to be installed. Cgminer comes with stratum proxy included, hence it can be used to mine through both getwork and stratum.
Reaper miner is an OpenCL miner for both nVidia and ATI/AMD GPUs, however it is more efficient on ATI cards. If pool requires stratum, stratum proxy has to be running.
Pooler cpuminer (or "minerd" ) is a miner for CPUs that was integrated into the Litecoin-qt client as well. If pool requires stratum, stratum proxy has to be running.
Stratum Mining Protocol (or Stratum Proxy) is a protocol written by slush originally for Bitcoin mining to improve pool-miner communications. This protocol was adopted by a range of other pools and by many of the Litecoin pools as well.

Bitcoin

Installing the Mining Software.
GUIminer -scrypt.
The installation procedure is the same as in the case of GUIminer for Bitcoin. Please refer to Bitcoin BASICs and Ubuntu 12.04.
Get the latest release of GUIminer -scrypt from git repository https://github.com/theRealTacoTime/poclbm.
Stratum Proxy.
./mining_proxy.py -o coinotron.com -p 3334.
wget https://github.com/slush0/stratum-mining-proxy/tarball/master tar xf slush0-stratum-mining-proxy-7b5c080.tar.gz cd slush0-stratum-mining-proxy-7b5c080/ sudo apt-get install python-dev sudo python setup.py install ./mining_proxy.py -o coinotron.com -p 3334.
Pooler cpuminer.
Extract it to anywhere on your computer.
After making it the executable file minerd will be created in the directory. You can start using miner (pooler cpuminer) to mine right away. Using the credentials from your pool. Remember, if your pool only uses stratum for mining, you have to have stratum running.
In this case you have to connect to,
-o URL of your pool -u workername -p woerkerpass So when stratum proxy is running and connected to a pool, it can be run as ./minerd -o localhost:8332 -u USER -p PASSWORD.
Download latest cgminer from ck.kolivas.org/apps/cgminer/ Make sure you have AMD APP SDK installed (See links in blog sidebar) as well as appropriate AMD drivers. Refer to guide at Bitcoin BASICs and Ubuntu 12.04 as this is the same miner with the extra argument "--scrypt" when running it.
cgminer --scrypt -o stratum+tcp://coinotron.com:3334 -u workername -p workerpass.
Reaper Miner.
reaper.cl reaper.conf litecoin.conf.
host localhost port 8332 user username pass password.
Where to Mine.
Just like with Bitcoin, there are two options for mining: solo and pooled mining.
Solo mining is when you are running the client in server mode and connect to it with your mining software. If you find a block, the whole 50LTC reward goes to you (
70$ currently). If, however, you do not find a block, there is no reward. This is a high risk high gain mining technique and it is not advised unless you have considerable hashing power.
Pooled mining is when a group of miners unite and mine as a team. Shares are given to each miner based on the amount of work (hashes solved) and when a block is found by any of the miners, the block reward is split among the miners, based on the amount of shares received. This allows a steadier, but smaller amount of payments and hence reduces the risk of never finding a block and never receiving anything.
Configure Solo Mining.
Solo mining requires to start the client software in server mode, have proper configuration and connect the mining software to the running client.
1. Firstly a litecoin.conf file has to be created in /Home/$USER/.litecoin This file has to contain the following lines:
Make sure you change username and password to something unique.
2. Kill the running litecoind or litecoin-qt if any of them are running. You can do this by right-clicking it in the top bar and choose "exit" or sudo killall litecoin-qt .
3. The client has to be launched in server mode in order for you to connect to it and mine in solo mode. To do this navigate to the unpacked folder and run litecoin-qt with the -server option.
4. Connecting to the server with any mining software is using the credentials given in the litecoin.conf file as created above.
host: 127.0.0.1 (or localhost) port: 9332 username: your unique username password: your unique passowrd.
Note: You will not see any shares being accepted when mining in solo. If a share is accepted, that means you have found a block. Also if you get a connection error, double-check the credentials to see if you have mistyped something.
Log into the system with your Bitcoin Wallet Address to do the Bitcoin mining with the GPU power.

10 Best Bitcoin Stocks to Buy in 2019.
If you wish to invest in the crypto market, you have 2 options: 1) directly purchase some cryptocurrency, or 2) you can buy stocks in companies that utilize BTC and introduce blockchain technologies within their platforms. These businesses will do just fine no matter what happens in the cryptocurrency world, but they will do even better if the crypto world has a good year in 2019.
If you prefer buying stocks, you won't need to go through the lengthy process of purchasing crypto on an exchange, managing a wallet or having to worry about price fluctuations, security, and documentation. Here, we give you our list of the 10 best Bitcoin stocks to buy.
Bitcoin Investment Options.
BTC currency.
As you know, Bitcoin is not a physical form of currency, nor is it a company or corporation that can go public. So there isn't exactly a stock for it. However, you can treat the BTC you have as an asset that can be bought and sold, and its value as the bitcoin stock price. The fluctuation in price can be tracked in the same way you can track any other stock in your portfolio.
Bitcoin Investment Trust.
There are other ways you can incorporate "bitcoin stock" into your portfolio as well. The Bitcoin Investment Trust is one notable option that operates similarly to an exchange-traded fund. It is a trust that owns the coins it is holding, and by buying shares of it, you can essentially bet on bitcoin value without actually owning any of your own (their bitcoins are secured using Xapo, Inc. as storage).
Bitcoin Futures.
Another possible attempt at investing in bitcoin's value without buying bitcoins is with bitcoin futures. Bitcoin futures allow you to essentially bet on the cryptocurrency's value in the future; if you think the price of BTC will go up in the future, you could buy a futures contract. Should your instinct be right, and the price goes up when the contract expires, you're owed an equal amount to the gains. Notable places that offer bitcoin futures contract are the Chicago Board Options Exchange, or CBOE, and financial market CME Group.
Contracts are leveraged in that you're paying a fraction of bitcoin's actual price when you buy futures, giving you a chance to profit off them. However, the contract has an expiration date in the near future. If the price is down when it expires, you can't simply hold and wait to see if it bounces back; you just lose.
Investing in Mining Technology.
The growth of Bitcoin mining as an industry has grown rapidly ever since the first BTC was mined nearly a decade ago. More powerful computers and hardware are required to give miners a better chance of successfully mining, and some companies have inadvertently become involved as a result.
Investing in Blockchain.
The most valuable aspect of bitcoin is the blockchain technology behind it, investing in blockchain is another way of tangentially investing in bitcoin without the worrisome volatility. There are many large companies that have been developing their own blockchain networks for a variety of purposes that may be worth looking into.
That doesn't mean it's risk-free, though. Blockchain technology is an intriguing development that could disrupt a number of huge industries, but at the moment, it's also a fashionable word to throw around.
Best Bitcoin Related Stocks.
Check out the following potential bitcoin stocks to invest in:
The tech giant has more than 1,500 employees who are focused on the development of projects that are powered by Blockchain technology. In 2017 IBM launched the blockchain services which power CLSNet, an automated settlement and trade netting processor which deals with overseas exchange transactions which aim to reduce the extra fees and hassles of converting currencies.
By collaborating with the Linux Foundation, they developed the Hyperledger Fabric, a project which specializes in developing and distributing corporate blockchain solutions. Nine international banks have enrolled to use IBM's we.trade blockchain payments service, two of them being HSBC and Deutsche Bank.
Another partnership with food retailers, most notably Walmart, to help quickly, efficiently, and securely track the supply chain to help ensure ideal food safety. They have also partnered with Maersk to work on a blockchain platform for global trade.
Microsoft is seeking to build a 'Blockchain as a Service' on its Azure cloud, becoming a genuine rival to Amazon when it comes to hosting cloud-based apps. The Azure Blockchain has also been implemented by big names, including NASDAQ and AT&T (NYSE: T). Microsoft Azure runs on the Ethereum blockchain, meaning that it depends on what decisions the Ethereum Foundation makes regarding its code updates.
Microsoft has also linked its blockchain services to several applications, such as Office 365 Outlook and Sharepoint Online, and apps of other companies, including Twitter and salesforce.com.
NVIDIA is one of the biggest graphics processing unit (GPU) manufacturers in the world. Its products are used in video games graphics as well as in mining, due to its computational performance required for producing Ethereum cryptocurrency.
As cryptocurrency and blockchain become more widespread, there will be more miners engaging in the process of earning coins and tokens. Furthermore, Nvidia's graphics chips are also designed with enough processing power to assist with artificial intelligence (AI) applications such as the Internet of Things (IoT) and autonomous vehicles, which will be some of the hottest topics in the coming years.
Everyone knows Amazon as the e-commerce giant. However, the company also employs technology services that are likely to gain from blockchain adoption.
Amazon Web Services (AWS) is a branch that takes care of the computing aspect that powers its e-commerce business. The company launched blockchain offerings for its corporate consumers, which allow them to create large blockchain platforms by using templates, thus enabling them to easily integrate the technology with other Amazon IT tools.
Amazon's blockchain case studies have been applied in a variety of situations, from helping farmers in their field data management and bringing healthcare improvements, to supply chain management.


Bitcoin

Overstock.com (OSTK)
Overstock.com has become the first US retailer to accept Bitcoin and its subsidiary, Medici Ventures, invests in promising Blockchain startups that cover such emerging areas as finance, digital identity, voting, etc.
TZero, which announced an exciting Initial Coin Offering (ICO) earlier this year, is offering a general ledger system for capital markets using cryptocurrencies. Investors can invest crypto coins such as Bitcoins and purchase real-life securities with them before receiving their profits in the same cryptocurrency. As TZero is operated on the Blockchain, it is said to be far cheaper to operate than more traditional security trading solutions.
MasterCard is among those companies that have supported blockchain, a technology with disruptive potential for its sector of business, for a very long time.
MasterCard offered banks Blockchain-based alternative for carrying out transactions in October 2017, discarding traditional credit cards. Curiously enough, MasterCard came to be the second Fortune 500 company to be involved in the development of decentralized payments, succeeding IBM. However, its Blockchain does not support cryptocurrencies, only fiat, meaning that it isn't a Bitcoin stock.
Bitcoin Investment Trust (GBTC)
Bitcoin Investment Trust is an open-ended grantor trust company. It is invested entirely and only in bitcoin and has a value that is based only on the price of bitcoin. What this company does is it provides investors with a means to gain exposure to the price movement of bitcoin without having to buy, store or keep bitcoins safe. Bitcoin Investment Trust is sponsored by Grayscale Investments which is a wholly-owned Digital Currency Group subsidiary. The concept is interesting in that each share represents ownership of 0.1 bitcoins and the value drops gradually over time as the company expenses are covered.
Glance Technologies is an active player in the cryptocurrency ECOSystem as they already own and operate the Glance Pay streamlined payment system. Glance Pay revolutionized the way in which smartphone users interact with merchants, order products, make payments, choose places to dine, access digital records such as payment receipts and earn rewards while doing so.
Glance has already built a strong network of merchants and consumers and uses the smartphone technology to offer incentives and other bonuses. The Glance Pay system is downloadable in various formats and provides tools for both merchants and consumers for maximum benefit. Glance Technologies continues to expand and offer more value-added products to its users. Glance Technologies (www.glance.tech) is based in Vancouver, British Columbia.
Founded in July of 2000, this company was designed to provide investment services to the blockchain ECOSystem. The company website actually references their activity as "a first mover on the NASDAQ focused on blockchain technology." The goal of this group is to revolutionize transactions with a system that has not been seen before.
To add to the unique ECOSystem created by Riot, they have also launched their own Bitcoin mining operation. The company only says that the Bitcoin mining operation will be the focal point of the expansion plans in place to move the company forward in the cryptocurrency world. The main focus of Riot Blockchain Inc. is the Bitcoin and Ethereum blockchains which put this group in strong positioning in the cryptocurrency world.
MGT Capital Investments, Inc. (MGTI)
MGT Capital Investments, Inc. has three main parts in its operation. They include cryptocurrency mining, proactive anti-hacking development, and the private phone. They are without a doubt one of the largest US-based Bitcoin miners and continue to expand with the Sentinel product line of cybersecurity technologies. The company has also formed a solid partnership with industry pioneer John McAfee which has led to multiple mobiles and personal tech device security systems. The Privacy Phone, through a partnership with Nordic IT, is a mobile phone that carries maximum privacy and extensive anti-hacking features.
How to Buy Bitcoin Stocks?
If you are one of those more conservative investors who prefer a traditional and safer approach, then you might select one of the above-mentioned blockchain stocks to invest in. This type of investing does not require you to go through the lengthy process of purchasing crypto on an exchange, managing a wallet or having to worry about the price fluctuations, security, and documentation.
You can buy stocks on the New York Stock Exchange (NYSE). Of course, you can't simply walk onto the floor of the NYSE and fill a shopping cart as you do at the grocery store. Instead, you must hire a brokerage firm to buy the stock on your behalf.
Brokers.
Different brokers offer different levels of support and advice to their clients, so it's important to choose the proper level of support for your needs. Once you've hired a broker, you will ask him to buy and sell stock for you whenever you wish to make a transaction.
Keep in mind that you'll pay a commission each time you buy or sell, so that's another point to keep in mind when shopping around for brokers and when figuring your profits and losses. Each brokerage firm has its own set of commission rates.
Online brokerage firm.
If you want to save money and feel confident about purchasing stock on your own, consider an online brokerage firm that allows you to open an online trading account. You simply open an account, deposit some money into it and log in when you wish to buy stock. This service is less expensive, as the broker buys stock on your behalf but does not analyze it for you or offer advice; they simply serve as an online bridge between you and the NYSE.
Once you decide what top bitcoin stocks you want, tell your broker what stock you wish to buy and how many shares you would like. When buying, you'll place a market order or a limit order. While a market order instructs your broker to simply buy shares of a certain stock, a limit order dictates the price you want to pay for the shares.
Contracts for Difference (CFDs)
If you don't wish to physically own the above Bitcoin stocks, you can always purchase Contracts for Difference (CFDs) for each instead. CFD brokers such as eToro - the world's leading social trading community - support stocks and foreign exchange, as well as leading cryptocurrencies. With CFDs, you simply place a 'Buy' or 'Sell' CFD order based on whether you expect the price on a stock to rise (Buy) or fall (Sell).
Even though stock investment might be safer than directly investing in cryptocurrencies as it is a regulated sector, that still doesn't guarantee against you losing money.
Bitcoin mining Company Spending $10M to Buy Back Shares.
China-based Canaan raked in $90 million from a 2019 IPO in the US. Now, it's using its capital to buy back shares while the price is near a historical low.
May I buy your shares? Image: Shutterstock.
Canaan is spending $10 million to buy back shares, which currently cost about $2. The maker of Bitcoin mining hardware took in $90 from a 2019 IPO, in which shares sold for $9. The Chinese company reported a year-over-year decline in net revenue of 26% in the second quarter.
Last November, Canaan, the Chinese company that makes computer chips and other hardware for Bitcoin mining rigs, priced its shares at $9 on the Nasdaq stock exchange as part of a $90 million initial public offering.
Now, with the price below $2 and near an all-time low, the company will spend up to $10 million to buy shares back.

Bitcoin

According to a company press release, "The number of [American Depositary Shares] repurchased and the timing of repurchases will depend on a number of factors, including, but not limited to, price, trading volume and general market conditions, along with Canaan's working capital requirements and general business conditions."
Canaan's unaudited second-quarter financial results , released last week, shed some light on the hardware maker's thinking. It reported year-over-year decreases in total computing power sold and total net revenues of 18.2% and 26.3%, respectively.
At the time, CEO Nangeng Zhang blamed the decline on the COVID-19 pandemic and Bitcoin price volatility associated with the Bitcoin halving in May -- when block rewards for mining were cut in half.
The COVID-19 outbreak, which originated in China, was already trending downward there by February, before the pandemic in the US and much of the rest of the world had yet spiked. That helps explains why Canaan's April-through-June earnings seem just fine. Quarter-over-quarter net revenue was up 160.9% to $25.2 million.
CFO Quanfu Hong said, "Looking ahead, we will continue to invest in those areas that can strengthen our product offerings, streamline our operations, and solidify our market leadership."
He added that the company was "confident in the underlying strength of our fundamentals and optimistic about the long-term growth prospects of our business."
If that's true, with the share price hovering at low levels and Chinese industry emerging from the pandemic, now is the time for Canaan to invest in itself.
Where can we buy shares of ASICMiner.
ASICminer did decide to keep the hardware and mine. They're selling shares with intent to payout the dividends from whatever profit is made.
Okay, so we got three players. ASICminer. Avalon. And butterfly labs. Obviously ASICMiner is the one most convenient. We don't need to do anything. We just pay. And get results.
So where can I buy ASICminer share?
Also how do they pay dividend?
So we own a share. Then we login to their site, and then we insert our bitcoin address? Or what?
Where is their website?
Disclaimer: At the time of this writing, I am a shareholder with ASICMiner.
Also be aware that the Bitcoin stock market is, like Bitcoin, very immature and not regulated. The risks involved are far greater than for a traditional stock market.
Like @Steven Roose just wrote, you can buy Pass-Through (PT) shares through two separate stock exchanges, BTC-TC and Bitfunder. I personally prefer the former due to its easier interface, but either works.
However, know that these are PT shares only. A PT means that you buy shares with someone who holds real shares with ASICMiner. In practice, it is much the same, but both PTs will charge a 0.5% fee from your revenues, and you don't get voting rights, so keep that in mind.
For 'real' shares, ASICMiner do not sell those directly. They were sold initially at a now defunct stock exchange (GLBSE) which turned into a bit of a disaster and after that, friedcat, the person in charge of ASICMiner, decided he did not want his stocks traded on any exchange for fear of similar accidents.
That said, there are a lot of people that hold 'real' shares, and these are sometimes put on auction over on Bitcointalk.org (check https://bitcointalk.org/index.php?board=73.0). In case you wint one of these auctions, the seller will transfer the sold amount by sending a message to friedcat with your email address and your Bitcoin address for dividends. I suggest using one of the escrow service providers on that forum to ensure the transfer goes smoothly and safely. Several escrow providers will do this for free, but it is customary to tip a few bitcents at least for their service.
Dividends for PT shares are paid to your exhange account and directly held shares are paid directly from friedcat to your Bitcoin address on file.
Beyond that, ASICMiner does not have a web page per se, but they keep everyone informed several times a week here: https://bitcointalk.org/index.php?topic=99497.0.
Like I said, be very careful about investing in Bitcoins and cryptocurrency stocks. There is no regulation, no recourse, and seldom any personally identifiable information.
And again, I am a current ASICMiner share holder, so keep that in mind as you read this.
