I have a lot of issues with them in the past, mainly from support and transactions that take days to confirm. Cryptopia is being beaten by the new exchanges that offered lower fee and cheap listing the only reason I'm here are from a few coins I'm holding that I can only trade here.
Well, I had problems with support system of almost every exchange and I remember that in the middle of the last bullrun Cryptopia was one of the hottest Crypto to Crypto exchanges out in the market.
Also I thought Cryptopia would have ended in a exit scam much before than now (not affirming that they got an exit with this happening) but they instead went ahead operating the exchange such for long time.
I hope for everyone who had coins in it to regain access to the coins as soon as possible!
