As soon as I knew about HITBTC exchange, there was no need in multiwallets. I am working at the stock exchange for more than six months, no problems arose. Minimal commissions, transaction speed is fantastic. There is rather good affiliate program, I'm happy with it.
Good to see some positive reviews too else their are quote a few threads where people are facing some or other issue with this exchange and thus people are scared to open the account in this exchange as they fear that they may lose their coins or cannot withdraw etc on time.
