Something seems fishy here...
shakaru claims to have "a mass mining op (in the 10's of ghz)", yet in his signature he's asking for donations to build his mining rig.
I read over all of his posts here (and I encourage anyone considering this investment to do the same), and most of the posts were from within the last week asking questions you would expect from someone trying to set up a miner for the first time (what cards to use, what kind of monetary return to expect, why something isn't working etc..)
I'm not saying he doesn't have good honest intentions, but something isn't adding up and I hope nobody gets burnt
