And on /topic: Bob didn't borrow. So what everybody is saying is pure speculation no-one knows his true angle.
He was tracked down and is in jail now. He's battling it out in court with the SEC. It doesn't look like anyone will be reimbursed, almost all of the funds are gone.
That story was to point out the fact that someone can appear legit and have REALLY good (the best in the bitcoin community) trust/feedback and still be a scammer. The ONLY way to be safe is to question everything and not take unnecessary risk. Feedback/trust ratings and judging someones trustworthiness won't work against a professional conman like PirateAt40.
Anyway I've made my point now. So long as you guys understand your taking risks, feel free to trade with BiPolarBob.
Maybe you should learn to read, this guy has paid back other people's loans. He has never asked people to pay him BTC, or promised them returns. He comes on once in a while and offers freebies. He gave out like ~20-30 LTC for free in one of his threads. If he asks for a loan etc it would be an obvious decline as he gives people stuff for free / next to free. Again, I think hes just having fun, I followed his wallet from the loan repayment and its well over 400BTC
