With all the network/mining attacks on ETN at the moment check your account and see if the transaction is still in the mempool before contacting cryptopia. I am getting mining deposits hours late to my own wallet, then transferring to Cryptopia. When going to Cryptopia it can take a long time because the transaction is still in the mempool. You can check if it is stuck by:
Opening ETN daemon,
Wait for sync,
Open ETN CLI,
Logging into your wallet,
If you have any "pending out" your ETN has not been mined yet.
Cryptiopia's ETN wallet is like 500 block behind right now. Is this usual?
