yeah it's hard to understand. i found one site with bit mining app. you can solo or work in groups.
at the moment I'm trying out this website to see if it will actually get a payout. It'll be years before I can buy anything decent though lol
if you're on a 64 bit system make sure you run it in a 64 bit browser. It works way faster that way
get the bitcoin app here and i guess it has to sync with the network first. you get an address and use that to receive the bitcoins
