How did my Azure miner go?
My 2 core Azure machine costs $85/month, and doing CPU only getting me 4.24+4.25= 8.5 kilohash/second (0.0000085 GH /s), compare that to the 3.6 GH /s that an ASIC $30 USB device provides.
And after 2 days of mining I didn't even get a single hash even accepted by the mining pool, effictivelly making my mining worth 0%.
Could this be faster?
On Azure, renting servers with a faster CPU (D & G-Series) would net negligble increases due to CPU mining.
The upcoming N-Series of VMs will have dedicated GPUs attached that you can offload work to. This would be an order of magnitude faster in mining. http://www.hpcwire.com/2015/09/29/microsoft-puts-gpu-boosters-on-azure-cloud/
The price per hour of a N-Series VM would be so high that you would be better off just paying to rent dedicated ASIC Bitcoin mining rigs e.g. there is a list at the bottom of this blog post https://www.bitcoinmining.com/best-bitcoin-cloud-mining-contract-reviews/

I am not able to understand after step 6. Can you please help me where to put my wallet address. Thanks in advance.
Is time to become rich and get more than $3,690 USD daily connect your mining wallet to my mining stream now and become a millionaire within 1 year i mine BTC, BCH, and ETH within 24 hours you can earn at least 0.5 BTC daily you can email me now [email protected].
I'm not suppose to be here doing this but i cant just help it, So straight to my story.....I started having interest in cryptocurrency when i saw my friend that invested early this year have earn about 70K USD as at now which he clearly explain to me how he started with 4K USD just with the help and guides of prof Sydney. He made me know how he contacted the prof and how the prof genuinely shed more light on crypto to him that they will be around forever and how it is very important to keep bitcoins even if it is 1 btc. I proceed to check a lot reviews on prof Sydney and i wasnt disappointed because i finally found a lot of good articles about bitcoins mining where nobody cries scamm. I think it pleasant to work with him which i did and i never regret emailing the prof. He help me mine 3.45 bitcoins in less than 72 hours and i am able to reinvest again so i can acquire more btc. I will implore you to hire only professionals when you need a miner. You can always email the prof right away to help you mine bitcoins anytime. (Profsydneycryptoconsultancy AT gmail DOT com)
I have been looking to get into Bitcoin mining but finding it too difficult to start. I bumped into an article online on investments and profit through Bitcoin mining and other alt coins. The daily,weekly,monthly income got me really, i couldn't comprehend the process but after further enlightenment via comment section i realized i can be assisted and this got me directed to crypto expert whom I contacted via his email address CryptobinaryExpert(at)Hotmail DOT com.Breaking financial barriers is one of the sweetest achievement one can achieve and with a profit of One hundred and twenty nine thousand dollars in a couple of weeks should be regarded as a gain though.
Have you ever gotten your bitcoins stolen from your wallet or invested in an ICO that turned out to be a scam, you are not alone because this happened to me too. I initially lost $90,000 in just 3 months from Cryptoallday, I contacted the authorities and they referred me to a bitcoin recovery company who helped me recover all my funds within less than 2 days...

How Azure Security Center detects a Bitcoin mining attack

[Bitcoin]

Azure Security Center helps customers deal with myriads of threats using advanced analytics backed by global threat intelligence. In addition, a team of security researchers often work directly with customers to gain insight into security incidents affecting Microsoft Azure customers, with the goal of constantly improving Security Center detection and alerting capabilities.
In the previous blog post "How Azure Security Center helps reveal a Cyberattack", security researchers detailed the stages of one real-world attack campaign that began with a brute force attack detected by Security Center and the steps taken to investigate and remediate the attack. In this post, we'll focus on an Azure Security Center detection that led researchers to discover a ring of mining activity, which made use of a well-known cryptocoin mining algorithm named Cryptonight.
Before we get into the details, let's quickly explain some terms that you'll see throughout this blog. "Cryptocoin Miners" are a special class of software that use mining algorithms to generate or "mine" cryptocoins, which are a form of digital currency. Mining software is often flagged as malicious because it hijacks system hardware resources like the Central Processing Unit (CPU) or Graphics Processing Unit (GPU) as well as network bandwidth of an affected host. Cryptonight is one such mining algorithm which relies specifically on the host's CPU. In our investigations, we've seen cryptocoin miners installed through a variety of techniques including malicious downloads, emails with malicious links, attachments downloaded by already-installed malware, peer to peer file sharing networks, and through cracked installers/bundlers.
Initial Azure Security Center alert details.
Our initial investigation started when Azure Security Center detected suspicious process execution and created an alert like the one below. The alert provided details such as date and time of the detected activity, affected resources, subscription information, and included a link to a detailed report about hacker tools like the one detected in this case.
We began a deeper investigation, which revealed the initial compromise was through a suspicious download that got detected as "HackTool: Win32/Keygen". We suspect one of the administrators on the box was trying to download tools that are usually used to patch or "crack" some software keys. Malware is frequently installed along with these tools allowing attackers a backdoor and access to the box.
Based on our log analysis, the attack began with the creation of a user account named "*server$" . The "*server$" account then created a scheduled task called "ngm". This task launched a batch script named "kit.bat" located in the "C:\Windows\Temp\ngmtx" folder. We then observed process named " servies.exe " being launched with cryptonight related parameters. Note : The ' bond007.01 ' represents the cryptocoin user's account behind this activity and 'x' represents the password.
Two days later we observed the same activity with different file names. In the screenshot below, sst.bat has now replaced kit.bat and mstdc.exe has replaced servies.exe . This same cycle of batch file and process execution was observed periodically.
These .bat scripts appear to be used for making connections to the crypto net pool (XCN or Shark coin) and launched by a scheduled task that restarts these connections approximately every hour.
Additional Observation: The downloaded executables used for connecting to the cryptocoin service and generating the cryptocoins are renamed from the original, 32.exe or 64.exe, to "mstdc.exe" and "servies.exe" respectively. These executable's naming schemes are based on an old technique used by attackers trying to hide malicious binaries in plain sight. The technique attempts to make files look like legitimate benign-sounding Windows filenames.
Mstdc.exe: " mstdc.exe " looks like " msdtc.exe " which is a legitimate executable on Windows systems, namely Microsoft Distributed Transaction Coordinator required by various applications such as Microsoft Exchange or SQL Server installed in clusters. Servies.exe: Similarly, " services.exe " is a legitimate Service Control Manager (SCM) is a special system process under the Windows NT family of operating systems, which starts, stops and interacts with Windows service processes. Here again attackers are trying to hide by using similar looking binaries. " Servies.exe " and " services.exe ", they look very similar, don't they? Great tactic used by attackers.
As we did our timeline log analysis, we noted other activity including wscript.exe using the "VBScript.Encode" to execute 'test.zip '.
On extraction, it revealed 'iissstt.dat' file that was communicating with an IP address in Korea. The 'mofcomp.exe' command appears to be registering the file iisstt.dat with WMI. The mofcomp.exe compiler parses a file containing MOF statements and adds the classes and class instances defined in the file to the WMI repository.

The initial compromise was the result of malware installation through cracked installers/bundlers which resulted in complete compromise of the machine. With that, our recommendation was first to rebuild the machine if possible. However, with the understanding that this sometimes cannot be done immediately, we recommend implementing the following remediation steps:
1. Password Policies : Reset passwords for all users of the affected host and ensure password policies meet best practices.
2. Defender Scan : Run a full antimalware scan using Microsoft Antimalware or another solution, which can flag potential malware.
3. Software Update Consideration : Ensure the OS and applications are being kept up to date. Azure Security Center can help you identify virtual machines that are missing critical and security OS updates.
4. OS Vulnerabilities & Version : Align your OS configurations with the recommended rules for the most hardened version of the OS. For example, do not allow passwords to be saved. Update the operating system (OS) version for your Cloud Service to the most recent version available for your OS family. Azure Security Center can help you identify OS configurations that do not align with these recommendations as well as Cloud Services running outdates OS version.
5. Backup : Regular backups are important not only for the software update management platform itself, but also for the servers that will be updated. To ensure that you have a rollback configuration in place in case an update fails, make sure to back up the system regularly.
6. Avoid Usage of Cracked Software : Using cracked software introduces unwanted risk into your home or business by way of malware and other threats that are associated with pirated software. Microsoft highly recommends evading usage of cracked software and following legal software policy as recommended by their respective organization.
More information can be found at:
7. Email Notification : Finally, configure Azure Security Center to send email notifications when threats like these are detected.
Click on Policy tile in Prevention Section. On the Security Policy blade, you pick which Subscription you want to configure Email Alerts for. This brings us to the Security Policy blade. Click on the Email Notifications option to configure email alerting.
An email alert from Azure Security Center will look like the one below.

Is Cryptocurrency Mining on Azure N-Series Profitable? And How To Do It Anyway.
The cryptocurrency craze is real, with BitCoin and other currencies surging in recent months. While the long-term viability of these are questioned by some, cryptocurrency mining has been going on for years and is the catalyst for how coins are distributed. Personally, I've mined cryptocurrency at home with my own ASIC and GPU equipment, but I've always wanted to test the viability of mining in the cloud. There are already several sites that sell out hashing power to buyers looking to mine cryptocurrency, and there are plenty of sellers willing to lease out their compute power to do so.
BitCoin and several other cryptocurrencies can be mined through varying methods, but ASIC mining is most efficient when available for a particular coin. GPU mining can be especially profitable on cryptocurrencies that are ASIC-resistant (where ASIC mining is not allowed in an effort to avoid a hardware arms race). CPU mining is barely a blip on the radar, as it is the least efficient method for cryptocurrency mining.
So how does this tie into Azure? About a year ago, Microsoft announced N-series virtual machines that actually have a healthy amount of GPU power. These instances are particularly useful for certain applications like 3D rendering, artificial intelligence, medical research, and CUDA-intensive computing. GPU's are much more powerful than what CPU's can do in these scenarios because of the type of algorithms they can run. These same algorithms can be used for hashing power to mine cryptocurrency quite well. Running this in Azure isn't particularly difficult and is exactly the same method as running it in-house, but I do want to test the best case scenario to evaluate the profitability of running mining operations in Azure.
First, we need to look at what GPU's are available in Azure. At the time of this posting, there are two GPU's available to use with N-series instances in Azure - NVIDIA Tesla K80 and Tesla M60. Since the M60 (NV SKU) is the more recent generation, we will be testing with those. The NV instances include the following SKU's:
Spinning up these instances in Azure is simple enough, but what cryptocurrency variation will be most profitable? I like to use a site called whattomine.com, which actually compares the mining profitability of cryptocurrencies by factoring in several variables like market value, mining difficulty, power consumption, and your specific hardware. This is incredibly useful info when looking for what to mine. For this test, we will evaluate two of the most profitable cryptocurrencies available (at the time of this post) that use two different mining algorithms - MonaCoin, which uses the Lyra2RE2 algorithm, and Zencash, which uses the Equihash algorithm. Both of these algorithms are designed for NVIDIA hardware, which suit our Azure instances well. To mine MonaCoin, we will use a miner called CCMiner; for Zencash, we will use a different miner called Zec Miner. Though these cryptocurrencies may provide little value to you, they can always be traded for your coin of your choice on several online exchanges. And yes, USD is included if fiat money is more your style.

[Bitcoin]

In Azure, we will deploy a Windows Server VM in the West US 2 region. You can find regions that support N-Series instances through Microsoft's regional availability site. If you have trouble finding the NV SKU, try switching your storage type from SSD to HDD. Be sure to monitor your usage closely since this SKU gets rather expensive.
I have deployed a simple NV6 Windows Server 2016 instance for this test. This size has one M60 GPU attached, so it should be straightforward to gauge performance. SKU's with multiple GPU's are available but scale up pretty evenly in mining performance.
Once the VM is deployed, download and install the latest NVIDIA drivers for the Tesla M60 - they do not come installed by default.
From here, you simply run your cryptocurrency miner using the same string you would use normally. This string will vary depending on your mining pool, algorithm, and username, but they generally look something like this:
CCMiner: ccminer -a lyra2v2 -o stratum+tcp://miningpool.com:2995 -u username -p password Zec Miner: miner.exe -server miningpool.coim -user username -pass password -port 3618.
And now... the results.
For the MonaCoin/Lyra2RE2/CCMiner test, the NV6 SKU was able to mine at a respectable 21Mh/S.
At current market rates, this would result in a payout of around 4.8 MonaCoins/month, or about $66/month - far below the $1004/month for the Azure VM.
Comparatively, a single NVIDIA GTX 1080 TI GPU would mine MonaCoin at around 63MH/s.
At current market rates, the 1080 TI GPU would result in a payout of around 14 MonaCoins/month, or about $202/month.
For the ZenCash/Equihash/Zec Miner test, the NV6 SKU was able to mine at 285 Sol/s.
At current market rates, this would result in a payout of around 2.2 Zen/month, or about $71/month - again, far below the $1004/month for the Azure VM.
Comparatively, a single NVIDIA GTX 1080 TI GPU would mine ZenCash at around 730 Sol/s.
At current market rates, the 1080 TI GPU would result in a payout of around 5.6 Zen/month, or about $182.44/month.
Here's all the results neatly compiled into a table.
As expected, the hash rate of the NVIDIA Tesla M60 running in Azure is far too low to pay for the NV6 instance size - you would lose around 80-90% of your investment to the Azure subscription cost. This could be due partly to mining algorithms being optimized more towards consumer GPU's, as the M60 and K80 are designed for workstation loads. Unless you have some free compute to burn through in Azure, I wouldn't recommend using these SKU's for *profitable* cryptocurrency mining. A better investment would be to buy hashing power directly from those willing to sell it, acquire your own mining hardware, or just buy the cryptocurrency instead in hopes of future gains.
How to Turn Your Azure Free Credits into Monero (XMR)
The rate can fluctuate between 1:1 and 1:10, i.e. in the best case you'll get almost 1$ worth of cryptocurrency for every 1$ spent on azure (depending on the current exchange-rates). With an MSDN Enterprise subscription you can mine cryptocurrency worth up to 149$ every month! This is possible because the newly introduced Azure-batch-service is dirt cheap!
Short summary: You'll need a azure-account with free-credit, e.g. from a MSDN-subscription Get a Monero-Wallet Start mining with the Azure-Batch-Service using the scripts provided here With the instructions provided here you will be mining Monero (XMR). Monero is one of the top-altcoins and better than bitcoin in virtually every aspect (i guess bitcoin beats Monero only in popularity).
You can see a screencast of the required steps in the video below (switch to fullscreen-mode with the button in the bottom-right corner to see it properly):
Setup Azure with Free Credit.
Do you have a MSDN-subscription from your day job? Great! You must have already noticed that Microsoft keeps sending you emails asking you to open an azure-account with up to 150$ monthly credit. Follow the instructions in the mail to claim your free credits. Note that by default you don't even have to enter your credit-card-number, so you can be sure that your mining is running purely on your monthly free credit.
Even if your company pays for the MSDN-subscription, the associated azure-account is your personal account and completely separated from the company. Your boss has no way of accessing it. Microsoft encourages people to use the free credits for testing and learning, and this is what you'll do: learning about using the azure-cloud and the blockchain-technology in a very practical way :-)
Note: It is your responsibility to comply with Azure's ToS. You will be banned very quickly if you do something that Azure does not like. You should only use free credits from legitimate sources (e.g. if you have a MSDN-subscription from your day-job).
Get a Monero-Wallet.
There are many ways how to create a Monero-wallet. The easiest is to setup a web-wallet with MyMonero.com.
Cryptocurrencies are notorious for being targets of spectacular hacks. A web-wallet like MyMonero.com is a good way to get started and it is safe as long as you don't enter your login-details on a phishing site (check your browser's address bar to make sure that you are really on MyMonero.com before entering your password!). However, once you have accumulated a non-trivial amount of Monero you should educate yourself about the possible alternatives!
By the way: if you don't already have a password-safe like keepass you should definitely start using one to store your wallet-details (and of course all other passwords you are using). Trust me, you'll regret it if you don't start now.

Setup the Azure Batch-Service.
After signing up for your azure-account you can click on the following link to create a new batch-account : https://portal.azure.com/#create/Microsoft.BatchAccount I recommend using Chrome to access the azure-portal. Fill the form with the following information:
Resource Group: Click 'Create New' and give it a name, e.g. 'myRecGroup' Account name: Just a name for your batch-account Location: Choose 'East US' Leave the other options at the default-settings. Click on 'Review+Create' at the bottom and then on 'Create" on the following page to create the batch-account.
Once you get the notification that your batch-account has been created (it will take a few seconds), go to your batch-account (link to your batch-accounts: https://portal.azure.com/#blade/HubsExtension/Resources/resourceType/Microsoft.Batch%2FbatchAccounts) and create a new pool : select 'Pools' and then click 'Add' . Fill the form with the following information:
Section 'Pool Detail': Pool ID: Just a name for your azure-pool VM Size: 'Standard F2 (2 Cores, 4GB)' (Choose the exact type! Otherwise you will not get the optimal hashrate!) Section 'Operating System': Publisher: Canonical SKU: 16-04 LTS Leave the other options at the default-settings. Click on 'OK' at the bottom to create the azure-pool .
Whenever the computers in your azure-pool get started up, they will execute a custom script which will download the mining-executable and start mining. Enter your Monero-wallet here and click on the button to generate your personalized startup-script (it should look similar to.
This is your personalized script:
Once the azure-pool is created, go to 'Start task' . Fill the form with the following information:
Command line: here you have to copy&paste your personalized script from the textfield above User identity: 'Task Autouser, Admin' Leave the other options at the default. Click on 'Save'
The last step is to tell Azure how many mining-nodes it should start for you. This depends on the amount of free credits available in your azure-account. Basically you want to use up as much of your monthly credit as possible without actually consuming all of your credit (otherwise you'll have to repeat the setup again in the next month because azure will delete your pools if your free credits are exhausted).
If azure is using your local currency instead of USD the numbers might look slightly different. If you run out of free credit before the end of the month, just reduce the number of nodes by one and try again.
Now go back to 'Overview' and click on 'Scale'. Enter the number from the table above in the field 'Low priority nodes' (e.g. 3 if you have MSDN Professional), and click on 'Save'. Congratulations! The azure cloud is now mining Monero for you!
Watching your Mining-Progress.
The script is using supportXMR.com as a mining-pool (don't mixup the terms 'mining-pool' and 'azure-pool' - they describe two totally different concepts). To see your mining-status, go to supportXMR.com/#/dashboard, scroll down to the bottom of the page and enter your wallet.
The VM takes around 5 minutes to startup and compile the mining-software. After that you will see the number of submitted hashes slowly increasing. The displayed hashrate will vary wildly - this is normal. Your pending balance will increase once the mining-pool finds a new block and it reaches the maturity depth. For a big pool like supportXMR.com this will take an hour or so. However, if the pool is unlucky, it can also take longer. The pending balance will be paid out to your wallet once it passes the minimum payout threshold. The default threshold is 0.3 XMR. The script on this site sets the default-password for the login to supportXMR.com to 'azurecloudminingscript'. After logging in you can change the password and reduce the payment threshold down to 0.1 XMR (note that the pool will charge higher fees for transferring smaller amounts). If you have MSDN Professional you'll have to mine a month or so until you reach 0.1 XMR and you can see a incoming payment in your wallet. Obviously it'll be faster if you have more azure-credits to spend.
Important Notes:
Some reasons why the hashrate displayed by the pool will vary a lot : Azure is running many virtual machines on a single physical server. If you are lucky the other virtual machines are running idle and you'll get a higher hashrate. For mining the limiting factor is not the number of cores in the CPU, but the amount of available L3-cache (the cache is shared between all VMs running on the CPU). In exchange for the low price azure does not guarantee 100% availability for the low-priority-VMs (in my experience the VMs are in fact available most of the time, though). The hashrate displayed by the pool is calculated from the number of submitted shares (i.e. shares which exceed the custom difficulty of the pool), not from the number of hashes your miner has actually calculated. Options for optimizing your hashrate In my experience azure-pools with fewer nodes result in the highest hashrate . So instead of setting up one azure-pool with e.g. 10 nodes you can setup 5 pools with only 2 nodes (you can use the identical startup-script for all azure-pools). This is because azure tends to allocate all nodes of a pool on a single physical CPU. You can also experiment with setting up your azure-pools in different regions . However, note that only few regions are actually available for use with free credits (East US, Southeast Asia and a few more) and that other regions may be more expensive than East US (if necessary, you'll have to reduce the total number of nodes to stay within your monthly free credits) All in all you can expect around 70H/s per used core. Azure has a standard-limit of 20 low-priority-cores per region . If the quota in your azure-account is less than that, you can request an increase of this quota through the azure support. I recommend not asking for more than 20 cores. We are operating in some kind of gray area here, you don't want to cause a big stir. If you want to mine with more than 20 cores i recommend setting up more azure-pools in other regions (the quota limits only the number of cores per region, nothings stops you from setting up more azure-pools in other regions). The script will restart itself every 2 days, fetching the latest version of the miner-executable from github. This is required because the mining-algorithm is regularly modified in order to prevent the development of ASIC-miners for Monero. If you don't like this behaviour you can change the phrase './run_xmr_stak.pl 30;' to './run_xmr_stak.pl;' in the generated script (i.e. remove the '30'). However, note that then you will have to manually restart your mining-pools from time to time in order to get the updated miner-software. Nothing in life is free. If you are mining with the script from this site the miner-executable will mine 4% of the time to my private wallet. From the cryptocurrency generated this way i pledge to donate half (2%) to the authors of xmr-stak. You can view this as a convenience-fee for getting a tested and streamlined mining-script.

How can I mine Monero or other altcoins using Azure Cloud Services?
Is there any way by which I can mine Monero or other altcoins using Azure Cloud Services.
2 Answers 2.
Sure - you can run cpuminer-multi on Azure or AWS, and it will CPU mine. You will need to find a pool to mine with.
Alternatively, if you want to solo mine, then you merely need to run a full Monero node, and from within bitmonerod you use the start_mining command. Details on the options you can pass to that command are available via the help command within bitmonerod .
Microsoft Azure VM selection for optimized mining.
I've come across a decent amount of Microsoft Azure credit and want to use it to to mine cryptocurrency.
I am writing to ask:
which computer to run the VM on - Azure provides a number of machines (https://azure.microsoft.com/en-us/pricing/details/virtual-machines/series/#a-series) optimized for various tasks - ' General Purpose Computing', 'Compute Optimized', 'Memory and Storage Optimized', 'GPU enabled' , ect. Under each of these categories, customers much choose the number of cores and amount ram (see https://azure.microsoft.com/en-us/pricing/calculator/?service=virtual-machines) to use.
I would like to know which machine type will mine the most efficiently , and how important are the different characteristics of a machine? (the number of cores, the amount of RAM, GB on disk?)

7 Easy Ways To Block Cryptocurrency Mining In Your Web Browser.
The Pirate Bay, the world's most popular torrent website, was recently spotted testing a Monero cryptocurrency miner on their websites. The website confessed that it could be using coin mining in future to keep the website running. This was followed by some other reports of similar nature.
This practice isn't new, but the Pirate Bay was the first popular website that was seen using a cryptocurrency miner. This has also fueled the ethics debate as the website owners are found to be keeping the visitors in the dark.
However, I was surprised to notice that many users who commented on the article and Facebook didn't mind their favorite website using their CPU power to earn revenue. This could be due to the fact that torrent websites are home to tons of notorious advertising. Before going ahead and telling you how to block cryptocurrency mining in the web browser, let me tell you how to find out if you're already becoming a target of such mining activities --
How to find out if my PC is secretly mining cryptocurrency?
Apart from ransomware, Bitcoin mining malware are rising in popularity at an exponential rate. In case the culprit is some website which is using your web browser to mine crypto coins, you can find that out easily.
The Pirate Bay users spotted the miner due to a huge spike in CPU usage when they visited the website. You can also use the same technique to see if a particular website is sweating your processor and earning money. In case most of the browser tabs are closed, and no applications are running, there are chances that you are becoming a target of such mining campaign. If you aren't much tech-savvy, you can perform hit and trial with the suspected websites and see which one of them is spiking the CPU usage. The tech-savvy users can perform this task much efficiently with the help of resource monitoring tools.
Apart from opening Windows Task Manager with Ctrl+Alt+Delete or Activity Monitor on Mac by pressing Command + Space and search for Activity Monitor , you can open Chrome's task manager by going to Menu > More Tools > Task Manager. It'll show tab-wise CPU usage in Chrome and help you spot the culprit.
How to block cryptocurrency mining in web browser?
Most of the websites that are making TPB-like headlines are using a new service called Coin Hive for mining. There are few simple ways to block such activities:
1. Use No Coin Chrome Extension.
Installing Chrome extensions is the most straightforward method to stop coin mining in the web browser. No Coin is one such free solution. This open-source extension is a reliable and safe way to control how a website is interacting with your web browser.
As soon as you visit a website, No Coin will detect and show if any such activity is going on. You'll see a red symbol as shown in the screenshot below. While this extension blocks any such activity, it also allows you to whitelist a website for a period of time.
2. Use minerBlock Chrome extension.
Just like No Coin, minerBlock Chrome extension is another open-source tool that you can use to block cryptocurrency mining in the web browser. These extensions currently list a few popular miner domains to their list, and they are expected to add more once they get popularity.
Here's how minerBlock notification looked like when I visited Coin Hive's website:
3. Block coin mining domains in hosts file.
This is the manual way of blocking particular domains that you don't find harmful or irritating. Due to such blocking, your browser won't be able to connect to these domains. We can edit the hosts file and redirect it to 0.0.0.0.
In Linux, you need to open the hosts file by running following command and add 0.0.0.0 coin-hive.com to the end of the document:
In Linux, run the following command:
For Windows, navigate to C:\Windows\System32\drivers\etc and edit the hosts document to add 0.0.0.0 coin-hive.com at the end.
Please note that this change blocks the mining scripts which are hosted by coin-hive.com. In case you come across other mining script domains, you can add them further down the line.
4. Block domains in Ad blocker.
Ad blocking extensions like AdBlock can help you block cryptocurrency mining. Depending on your web browser, you can find relevant settings to block particular domains. For example, in Chrome, for AdBlock, navigate to the list of extension and find AdBlock. There, look for Customize > Block an ad by its URL . Then, add the following text in the text box:
5. Use NoScripts in Firefox.
For Firefox, you can use JavaScript-blocking extensions like NoScript. Before using it to block cryptocurrency mining in the web browser, please note that it's pretty aggressive and it could break lots of websites as it disables all scripts running on pages. If you're using Tor Browser, you would already be knowing about NoScripts and its use. You can use any one of these methods to get rid of the cryptocurrency mining in the web browser.
6. How to block CoinHive using Opera web browser.
With release of Opera 50 web browser, the company brought in-built functionality to block CoinHive scripts and cryptocurrency mining techniques. This will allow the users to make sure that their computers don't go crazy whenever any website using the digital coin mining technique is encountered. The users can find this option in Settings (Preferences on macOS) > Basic > Block ads and under the Recommended lists of ad filters.
7. Use Malwarebytes.
Installing a reputed antimalware solution could act as an alternative to installing Chrome anti miner extensions like Nocoin. The advantage of using a solution like Malwarebytes is that it offers protection to your complete device. Malwarebytes also offers an Android app which comes with 30 days free trial. Other top antivirus programmes for your computer have also started offering miner adblocking protection.
Should I really go ahead and stop cryptocurrency mining?
The answer to this question depends on the website which is using a crypto miner. If the website is notifying you as soon as you visit it and you're comfortable with it, then it's no harm. Another point that you must take into consideration is the mining load that your CPU would bear. A website should also let you know how much processing power does it intend to utilize.
In case you're willing to support your favorite website via this alternative source of revenue and they are being honest about their practices, things are fine.

In this guide we'll look at how mining works, why it's a necessary component of bitcoin infrastructure, and whether it's a good way of making a buck.
Must read: Cloud mining warning.
Cloud mining will almost never be profitable. This is because the breakeven point, where you make as much money from cloud mining as you put into it, will keep moving backwards and you'll typically never be able to reach it.
The reason it moves back is because Bitcoin mining difficulty tends to rise over time, especially as Bitcoin prices do. This means the amount of Bitcoin you get from cloud mining will usually decrease over time, which pushes back the breakeven point. Bitcoin mining difficulty will usually only drop if Bitcoin prices do, but if that happens then your Bitcoin is worth less, which also pushes back the breakeven point.
As such, even if a cloud mining contract looks like it will be profitable, you're still more likely to lose more than you earn.
In the rare cases where a cloud mining contract turns out to be profitable, it will have been more profitable to simply buy cryptocurrency instead of mine it.

Whenever a transaction is made in bitcoin, a record of it is made on a block containing other recent transactions, like a page in a ledger. Once the block is full, bitcoin miners compete against each other to verify and validate the block and all its transactions by solving a complex cryptographic problem.
The first miner to accomplish this is awarded a set amount of bitcoin, based on the mining difficulty at the time. The verified block is then added to the blockchain, a history of all blocks verified since the beginning of bitcoin, and transmitted to all users of bitcoin so that they can have the latest blockchain.
At the heart of Bitcoin mining lies a hard, mathematical problem. The goal is to ensure that the process of adding a new block to the blockchain requires a lot of work. That helps to ensure that any hacker tampering with the transactions needs not only to mess with the transactions but also win the "race" of Bitcoin mining.
So how does it work?
Basics of cryptography.
SHA-256 - the mining algorithm used by bitcoin - is a one-way cryptographic algorithm. When you pass a word through SHA-256 you will be given back an unrecognizable string of letters and numbers called a "HASH".
For example, the SHA-256 of the word "BUTTERFLY" (source) is "8c62ace4f9ef8ccd08ca6fb992a8524bb7dbdc0530654bd254c9da07a660949a" (HASH). This seemingly random string of letters and numbers has three important properties:
Only the word "BUTTERFLY" will ever give that specific HASH. The word "BUTTERFLY" will always give back that exact HASH. There is no way of figuring out the word "BUTTERFLY" if you only know the HASH.
With this information, we can now start piecing together the mining process.
The mining process.
Bitcoin mining involves three variables: the block, the mining difficulty and a random number. Here's how it all comes together:
Imagine our block consists of the word "BUTTERFLY" discussed earlier. In reality, the block would contain a list of recent, unverified transactions, but let's keep it simple. In order for the block to be solved, bitcoin uses a deceptively simple test: If the HASH result of the block starts with a certain number of zeros, the block is considered verified. This number of zeros is the "mining difficulty" and is increased as more miners join the bitcoin network. For our example, let's say that we have a mining difficulty of just two, ie, our HASH must start with two zeros.
