No problem with security, although, I do not keep any coin in any exchange for prolonged periods, ever. Was on the chat box and got banned for saying Dash is king. Apparently, it was too much. I am not allowed to say that but, it seems, telling everyone Etx is the God coin, is ok by them. They preceded to say something along the lines of, we can all buy Dash and become "hobos". I'm not saying its not a good place to buy coin, nor am saying it has security issues. It's a great place to buy and trade coin, however, and this is my opinion, they have too much control of the market, and they are biased to certain coins that rhyme with Etx. Ignore the troll box and it's fine, pay attention to the bs they spew, and it's enough to make one sick.
