i'm under the impression that the mtgox incident was much more catastrophic than bfx hack, in terms of size & market impact; as in waaay more catastrophic;
i wasn't around when it happened & i might be totally wrong. (currently doing a little digging on what happened then.)
but is it fair to compare bfx hack with mtgox shutdown?!
I get the impression that gox had a lot of historical users but it wasn't the market leader by that point. china and bitstamp had both surpassed it. the problem was that people were using it as a wallet and there were old coins on there too so the number of coins was a lot higher than bitfinex. it was a long time brewing and it wiped out a lot of the old guard.
The Gox catastrophe was telegraphed a miles in advance. For months and months, account holders couldn't withdraw fiat, but could withdraw BTC. However, partly as a result of this, Gox generally traded at a $50-$60 premium to Stamp, which back then was the out and out market leader in terms of USD exchanges, and yeah, a huge amount of the BTC lost on Gox, was early adopter BTC. BTC bought in double or even single figures, but with losses priced in upper treble figures. Bitfinex on the otherhand, has grown enormously over the past 18 months or so, and obviously, Finex has a lot of 'new' money on it....or had a lot of new money on it.
In all honesty, I think this Finex theft will have more serious impacts on Bitcoin than MtGox. Back when MtGox happened, there was still a widespread belief that Bitcoin was destined for 4 figures. These days, Bitcoin needs a minimum price of $500 to make it worthwhile for the miners to have their farms running, powering the Bitcoin network. Going forward from here, even if BTC gets back up to mid $600s, I think it is very likely that Bitcoin will dip well below that $500 threshold. A whole bunch of BTC liquidity providers aren't going to want to play anymore. A whole bunch don't have the means to play anymore, and then there is the small matter of 120K BTC that will eventually find itself being fed to the market going forward. Going to be a testing time for Bitcoin imo.
