I too can confirm that Cryptopia was good before but currently it's best to be avoided. NEO withdrawal (#3371022) stuck at processing since March 3. In February a NEO withdrawal went through in less than 30 minutes... I also sent a support ticket (#227549), but received an automatic email that I can expect an answer in 23 days. I hope it gets resolved sooner than that.
Cryptopia was a nice exchange, but issues like this make a lot of people disappointed. The clock is ticking and I'm sure every day they lose more and more customers... I hope they fix this mess soon.
