The trading platform is not bad, esp. on the phone. But I can only give a 2-star because the service efficiency is worse than a traditional bank account. 1) Deposit (etransfer) is fast (almost instant), withdrawl takes 3-5 biz day. 2) Revocation of coin withdrawl without warning, either in writing or oral. 3) Chat Support (live) can be considered NONE (bot only answers to standard Q&A which is mostly useless when you need to speak to someone); Chat Support (email) always delayed. 4) Phone line is worse than hotline, as the line is ALWAYS busy. I only managed to call in once and was sent to a voice mail promising to call back but never did.
