What a mess, I feel terrible for people that lost their money to this company. Yes, it is lost, getting 600gh at this point is a joke. It's an expensive but very important lesson we can all learn from. My guess is BFL has no choice but to scam their customers at this point. I doubt they have the money left to provide refunds.
not to defend bfl. as they have not done well by me,but 600gh hashing will earn something maybe 1 coin.
still looks like a big loss.
