Feel your pain here brother, have had several transactions do this and some they are taking weeks to get back to my support tickets!
But we gotta be patient with cryptopia, I read a post on their blog in december last year and they said that in december of 2016 they were
actually considering shutting down. Needless to say in 2017 everything changed.
They like doubled their amount of users in a matter of weeks late last year, there is just no way for them to keep up, and this is all the
exchanges not just cryptopia. The exchanges will catch up dont worry...
There are a bunch of new exchanges and teams that have recently gone through an ico process, and will probably be released from mid this year onwards. My guess is that when these are released, there should be less pressure on existing exchanges and more competition (I hope).
Don't feel too bad for Cryptopia - they are getting around $100k a listing now (although the asking price without negotiation is even higher).
ya thats true they are making a killing on listings and are taking forever to get the coins listed, magnet payed for a listing weeks ago and we still havent been listed.
hope that 2018 is a big year for decentralized exchanges, they are better for anonymity for tax purposes too
