hashfast is the worst SCAM i never seen ! dont buy anything from them !
From what I am reading about HF, I would say they are a close tie with BFL. It really is like dejavu for me to read about this crap. The only difference for me is, I did not order from HF. Those of you that did, you have my sympathies. I do know what it feels like to have a large sum of money in jeopardy.
Best of Luck.
