Not sure if you got a lucky draw, all I know is that it can be a horrible experience when you deposit any coin.. Whenever I've deposited BTC it can take like 20 confirmations before it even pops up under my deposits and it still has to get another 6 confirmations. I still like them, and I like the transfer feature, however you should not be in a hurry when you are using their exchange. Never had any major issues though so if they just keep it going they might continue climbing the ranks .
