I'm kinda agree with you but you can't dismiss the valid issue raised by this fellow.
Bitcore needs at least one more, high quality and trusted exchange. No doubts it can only help the entire project. Right now it feels like dev have abandoned this thread, not sure why, as he could make new account or retrieve his old one (that was presumably hacked).
Guys maybe it is time to consider using tradesatoshi instead of cryptopia. There are daily limits there, of 2K$ so bare in mind that without verification you are somehow limited. I was't suing this exchange for a while, I'm not 100% sure how are things there but in the past it was quite smooth and fast, maybe worth to try it out? Note: coin informations are outdated on tradesatoshi (I don;t think it poses any threat).
