Can anyone give me a ruff estiment on how many Gh/s you need here to make some btc? I mean do i have to spend 5 btc, to get enough gh/s to accually get some btc in return
you can spend as much or as little as you want its more of the idea of buying at a good price and being able to resell those gh/s a few days later at a higher rate to make a decent return. Consider the mining just a small interest payment since it will not be much.
