I think everything is fixed by now. For me everything works like charm.
I think the biggest danger that Bitfinex faces is the reaction of the paranoid bitcoin community if there is a small bug or something. Its funny when in bitcoin something goes offline or there is a bug within hours people are yelling scam, fraud!
So if anything like that happens to Bitfinex, I think users will instantly move there money out and you know guys, even major banks can collapse if there is a panic. There is just not enough funds to liquidate in that short period if time.
Not everyone will withdraw and by far not everyone will notice. But the way you write sounds like you were not here when so many online wallets, exchanges and whatever went down. What do you think how things start? With slow little signs here and there.
Its simply a thing learned from the past. It may be nothing very well but if it is something you will be happy if you did not lose anything.
