This is definitely the best exchange, I don't even know why would any exchange risk to steal people's money since bigger exchanges earn much enough to be "not worth it" to risk legal consequences. I myself was scammed from crapcoins by Cryptsy because I was too lazy to install multiple wallets. Last time I checked my crapcoins were only worth few bucks but the uncertanity what type of coins I had there makes me anxious since I checked them 2 years ago but I hope they aren't still worth much. Maybe some day there will be multicoin client for computers.
