Accusations? I consider them to be near facts when it comes to Bitfinex. I say near because it's impossible to provide actual proof.
That's the point, without proof they are just accusations.
I remember how mad the overall community was at Bitfinex, which was well justified, and now they miraculously settled their debt, it's all fine again? Sorry, but that doesn't go with me. I am fairly sure that if they successfully managed to pull off a faked hack, they have no problems in doing it again at a later point. People only learn when they have to pay for it, that's for sure.
I remember how mad the community was when Big Vern ran off with all the coins from Cryptsy (including some of mine) and Tradefortress from inputs.io. In both those cases, they didn't settle their debt, they just vanished. I think that if Bitfinex had pulled off a fake hack that would have been the exit from the scam and they would be sunning themselves on a nice yacht in the Caribbean right now. I also understand that those affected see it that they lost a lot in terms of potential gains if they had been able to keep their coins, so that's where the anger comes from. I do think that settling their debt goes a long way to rectify what happened. That is just my assessment and why I don't think having coins there is any riskier than any of the other exchanges available right now.
