In the media, we often hear about Bitcoin miners who consume an unnecessarily large amount of electricity with their computing machines and thus pose a risk to the earth and its climate. Especially after the introduction of Proof of Stake for newer cryptocurrencies, I am also rather skeptical about the Proof of Work approach. Nevertheless, building passive income in cryptocurrency has always interested me. If you browse the coinmarketcap.com website, you will come across many projects in which each individual can participate, generate real value, and earn money in the process. One of these projects is Storj, in which you can participate by running a so-called Storj node.
