I'm a young miner that has been in the bitcoin community since 2011 and was deep into bitcoin back when the original $1000+ jumps were happening and made some money with it.. the problem is i've been away for a while and i'm having trouble finding the best miner (50Gh-100) That's power efficient and not a crazy amount so maybe with altcoins there could be a jump in value. anyone have any suggestions at todays current best power efficient miners? Thanks!
