I have deposit, trading, and withdrawal several times already and no problem at all, I read a lot of complaints but they already solved those issues I don't want to say that it's not going to happen again but so far Cryptopia is legit although there are backlogs in their support ticket, I recommend to trade with cautions.
When it does work it works like expected but the support is horrendous. Waiting weeks if not months for support ticket is frustrating.
There are still people who's missing deposits and withdrawals over a month. Cryptopia is really a hit and a big miss.
