Cryptsy..
If you have most of your coins in Bitfinex.. there will be little mercy when they disappear.
Surely there could not be that many people storing most of their wealth on an exchange after all that has happened in the last few years. although the height of human stupidity still amazes me.
Bitcoin and cryptocurrency is just eight years with us and every process as we know, takes some getting used to. So far, most bitcoiners are well aware that an exchange, is never to be confused for a bank. Moreover, there are now history, one can fall back on, to decipher a thing or two about an exchange about to sink and make good one's escape.
Like when an exchange starts to quote rates that are totally out of range from those of other exchanges, that is when to gather all one got and take to one's heels.
