I was previously trading on Bitterex until they brought up the verification issue. But I still recommend them as the best exchangers for trading. I'm looking out for some decentralized exchanges good enough for trading. However, you must know that all exchanging sites are risky.
Exchanges are risky and this fact. You can never trust them blindly but in race of such safety and security you must have to choose a better exchange because you cant progress without it. There must be some people who are talking about the fake and bugs in such exchanges, they may be right but majority times they only want to make a buzz. Bittrex is better in all cases than any other exchange.
