How mining (weird ?)

You need some hardware first, like ASIC machines like AntMiner or graphic cards. You also need to look at which cryptocurrency you want to mine BECAUSE the hardware depends how it calculates the crypto. So some hardwares are like to be better with some crypto than others (even for graphic cards).

You also need to configure network and the softwares and setup the pool to collect those cryptos. I don't really know how to do it but I guess someone here is still good at this domain.

Anyway, you need to make profits and not losses because you consumed too much electricity. Take care of the bills!

And remember: hardwares makes loud sounds due to heatsinks and stuffs like that.
