For all the criticism Crypsty gets it's one of the only exchanges I know that shows the owners identity and has a physical location. Without that you are basically trusting someone you don't know like a random person on a forum with your money. Yeah they could have a good reputation but say they did lose a large amount of money that they couldn't possibly pay back then they have all the motivation in the world to disappear without paying you back.

Of course this is also why we need decentralised trading like second gen coins NXT, Qora and Etherium etc.
