Hi guys last year i started to get into this when it jumped up to 1100 or so, and was giving some btc to a guy lmontrose that was going to get the new machines, well i just came back from a deployment, looks like he failed and made off with some of my btc

But i would like to know how, if its worth mining and what are the best ways to do it now, i have not even looked at whats out in the last year.

im guess GPU are not worth it anymore, and last i heard 3 was fastest, not sure, and now that btc is really cheap are the machines still expensive?

thanks for any help
