This tutorial is based on terminal commands.If you are not familiar with terminal commands on your Raspberry Pi, we highly recommend reviewing 25+ Linux Commands Raspberry Pi Users Need to Know first How to Mine for Cryptocurrency on Raspberry Pi
We will start by creating our account with Minergate , a cryptocurrency mining pool with 3.5 million users worldwide for Bitcoin Gold, Zcash, Ethereum, Ethereum Classic, and Monero .This tutorial is specific to mining Monero as it was the only cryptocurrency I had any level of success with.(Image credit: Tom’s Hardware)
2.Boot your Raspberry Pi.
If you don’t already have a microSD card see our article on how to set up a Raspberry Pi for the first time or how to do a headless Raspberry Pi install .
3.If you are using Raspberry Pi OS with Desktop, open a Terminal , or press Ctrl-T .If you are using Raspberry Pi Lite, login as you would normally.
4.
Once in your terminal, run the following updates and install the necessary dependencies: sudo apt-get update && sudo apt-get upgrade -y sudo apt install git automake autoconf libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev cd cpuminer-multi (Image credit: Tom’s Hardware)
5.Now, let’s compile the mining code with the following three commands.
This step will take a couple of minutes on a Raspberry Pi 4.sudo ./autogen.sh sudo ./configure sudo ./build.sh (Image credit: Tom’s Hardware)
6.
After building and configuring our mining software on our Raspberry Pi, let’s start mining for Monero ! Enter the following terminal command to start the miner, replacing YOUR_EMAIL with the email address you used to signup for your Minergate account../cpuminer -a cryptonight -o stratum+tcp://xmr.pool.minergate.com:45700 -u YOUR_EMAIL
You should see the mining software start and hopefully see a few shares ‘accepted’ with ‘yes!’ (Image credit: Tom’s Hardware)
7.Let’s check your Minergate Dashboard by logging into https://minergate.com/internal .You can do this on a Chromium browser if using Raspberry Pi Desktop, or on your PC.
Scroll down your dashboard until you see Monero.If everything is working, your Monero Status will indicate ONLINE.Congratulations! You’re now mining for Monero! (Image credit: Tom’s Hardware) How to Start Raspberry Pi Crypto Mining on Boot
To automatically start our cryptocurrency miner on boot on our Raspberry Pi, we’ll use the Crontab method.crontab -e
If you haven’t set the crontab previously, you’ll see the response “no crontab for pi, Select an editor.”
1.
Type ‘1’ and hit Enter .
2.This will open a new crontab file, arrow down to the bottom of your crontab file and enter the command below, replacing YOUR_EMAIL, with the email address you used when creating your Minergate account @reboot sudo /cpuminer-multi/cpuminer -a cryptonight -o stratum+tcp://xmr.pool.minergate.com:45700 -u YOUR_EMAIL (Image credit: Tom’s Hardware)
4.Press Ctrl-X , and y to save your crontab .
5.Now reboot your Pi by typing ‘ sudo reboot ’ in your Terminal .
How much Monero did I mine with Raspberry Pi?
My Raspberry Pi 4 calculated 357 good shares in about 8 hours of run time.Miners are rewarded for good shares .Bad Shares are calculations where I came up with the right answer, but my Pi produced the results slower than another computer.Miners only get paid when they submit the correct answer first.
Invalid shares are the worst as a miner is penalized for every invalid share due to possible fraudulent activity.I was a bit worried when my first 4 shares were marked as invalid shares.

357 good shares = 0.1410642 Monero = 0.00015569 USD
I made the equivalent of 1/100th of a penny in 8 hours.
In order to withdraw my Monero, I needed a minimum of 0.05 Monero , approximately equal to $5.811 USD .
(Exchange rate at the time of the writing of this article.) At a pace of accumulating 0.1410642 Monero per 8 hours , it would take me 3,762 years to reach the minimum withdrawal threshold of 0.05 Monero.(Image credit: Tom’s Hardware) Lessons Learned about Raspberry Pi Crypto mining
As stated at the beginning of this article, the purpose of this exercise was to learn about cryptocurrency and not to make a profit.
Cryptocurrency mining rewards are calculated by shares and hash rates.My hash rate varied from 1.6 H/s to 33.3 H/s.The average hash rate for the pool was 10.27 MH/s, approximately 3 million times my Pi’s hash rate.For reference, 1 MH/s is 1,000,000 hashes per second.The mining pool company (in this case Minergate), also charges a small commission on your transactions.You have the choice of luck based commission (higher risk, higher reward), or Pay Per Share (higher commission for Minergate, but less risk).At various points during the writing of this article, my Pi had numerous ‘time out’ errors and ‘send_line failed.’ Sometimes a reboot of the Pi would help, and sometimes, the miner would eventually start working again without human intervention.
