So, the reason why Cryptopia isn't trading this anymore is because the coin was hacked on their site, and Tradesatoshi is running the wallet and trading successfully? Isn't that a breach of contract for Cryptopia?
Have they updated to 2.3.x?
Well the answer to that question is no... they still have not upgraded to 2.3.x. Tradesatoshi has CAP listed as fork. Cryptopia has it listed as "working with dev" and "delisting"...
Take it for what you will.
