The Raspberry Pi is a great hobby mini-computer, but what if we can also use it to make money?
The rise of Bitcoin has created an interest in cryptocurrency mining. If you have a spare Raspberry Pi lying around, you can put it to work mining for digital currency.
I used Ubuntu server 20.04.3 long-term support (LTS), which supports Raspberry Pi 3, 4 and 400 on the 64-bit version, and an old Raspberry Pi 3 Model B revision 1.2 that I had lying around.
I am going to mine Duino-Coin, which is a coin that can be mined with an array of technologies, including Arduinos ESP8266/32 boards, Raspberry Pis and computers, as well asWi-Fi routers, smart TVs, smartphones, smartwatches, single-board computers (SBCs), microcontroller units (MCUs) and graphics processing units (GPUs).
Installing Ubuntu on the Raspberry Pi is a very straightforward process. You can find detailed documentation on the Ubuntu website.
After the installation and boot of Raspberry Pi, we can log in with secure shell protocol (SSH) and should be presented with the Ubuntu server start screen:
We can even see the temperature of the Raspberry Pi. Mine seems to be at 45 degrees Celsius just after boot.

To set up Duino-Coin, all you need to do is follow these commands. We start by installing all the dependencies:
Then we can clone the Duino-Coin repository:
We also need to generate a wallet where our mining profits are going to be added. Duino-Coin has a few wallet options, including a graphical user interface wallet, a command line interface wallet and a web wallet.
I chose the web wallet because it has additional features, like the ability to view your miner stats and calculate estimated profits.
To run the miner, we need to execute the following command:
On the first run, the script will ask for the following configuration:
Then the miner will start its work. And that’s all you need to do to start mining Duino-Coin on the Raspberry Pi.

You can go to your wallet to check your miner stats:
As you can see, after a couple of hours, the results are not a million dollars but an estimated $0.003 daily.
Keep in mind, however that this is an old Raspberry Pi 3. New models like the Raspberry Pi 4b can produce up to 1.75 MH/s, compared to my ridiculously low 252.35 KH/s.
While I might not get rich, it took me less than five minutes to start mining and I had an extra Raspberry Pi. It’s a nice, slow-growing side income with little effort. Maybe in a year, I’ll be able to afford a nice coffee.
Crypto mining is a hot topic in the world of technology and finance. Raspberry Pi offers an inexpensive entry point for those looking to start making money through cryptocurrency.
While it’s not as powerful or efficient as some more expensive solutions, it can still provide you with a steady stream of income.
