If you want to become a miner, it is actually relatively simple. Buy a dedicated computing device and download the mining software to start mining. Mining does not require the miners to do it themselves. In fact, the computer performs specific operations. Miners only need to ensure the power supply and the network connection of the computer.
It's simple to do it but it's not simple at all if you want to profit. You need good knowledge to choose profitably coins, do some researches about how to take care of your mining tools (air circulation, how to build your rig if you want to mine altcoins, etc), thinking about electricity cost.
And most importantly, now you need big capital to do it. Before 2018, many people were saying that mining is a low-risk low return investment, but now it's not.
