If you deposit one dollar on an exchange, you get one dollar minus fee, no matter you trust the exchange or not.
I have deposited USD on ccedk several times and they worked well. Ronny has a real identity and a business track record. Who gets a trail of your money on btc-e? I think btc-e is reliable due to its track record. But if it vanishes now I have no idea where to get my money back.
Itās much much more difficult to steal fiat than crypto by hacking into the exchange site, which is one of the main cause of exchange default.
