why do people keep saying 65 million.
bitfinex was hacked (or stole) 119,000 bitcoin which was nearly 75 million by the time of the hack. even with $600 it is 71.4 million.
Unfortunately it's highly unlikely that the Bitfinex users will receive back any significant amount - unless someone finds 100k+ BTC under his sofa...

The most realistic scenario for Bitfinex is bankruptcy. I doubt that it will be possible to find a buyer that will reimburse the losses. The amount is too high and the Bitfinex trading system has been now been proven to have security flaws. Nobody is going to pay $60m for that.
Even if the CFTC regulations prohibited cold storage that's no excuse for the security practice at Bitfinex. They could have used a proper multisig setup - apparently they did use multisig indeed, but they did not effectively oversee the safekeeping of the keys.
nobody is going to do anything for bitfinex sine they were just another unlicensed exchage site opperating without any legal license!
Now most likely another wave of media FUD will start, portraying Bitcoin as unsafe and a hacker's paradise. However I doubt the consequences will be as bad as after the Mt.Gox disaster, since the number of informed people is a bit higher now and the losses are less extreme. Hopefully all other exchanges will improve their security measures as a result.
the media is going to have a field day with their click-bait articles but i don't think they have any effect any longer.
and i also doubt that other exchanges will change anything. because it is not the first time a hack like this happened!!
