ETB did a token swap yesterday, it's likely you sent old tokens to Cryptopia instead of the new ones which is why they won't have been credited to you. Open a support ticket with Cryptopia, they'll return the old tokens to you (it may take a day or 3) so that you can then upgrade the tokens to the new smart contract after which you can deposit them to Cryptopia for trading.
Details on on the upgrade (and the how to): https://blog.ethbits.com/2017/06/14/token-upgrade/

Extremely appreciated for the reply, in the meanwhile I've already opened a support ticket with Cryptopia.
Thank you for the information, you've been of great help.
I'll now close this as Cryptopia should be able to solve it for me.
