This was discussed in another cryptsy thread. Richie says bittrex has never been hacked. And while some of those other exchanges have no doubt been hacked I do not believe that all of them have. Also keep in mind, Bitstamp has been hacked. So whether or not an exchange has been hacked is not necessarily the same thing as saying the exchange is solvent or fair or operating with integrity or anything else.
Those are great points. Thank you for making them. I completely agree "whether or not an exchange has been hacked is not necessarily the same thing as saying the exchange is solvent or fair or operating with integrity or anything else."
I think, if any one of those things, this thread is about an exchange operating with integrity (or not).
I will also revise the post you mentioned to avoid the potential of misinforming anyone.
