It's been long time since i use cryptopia (only to sell small amount altcoin), but IIRC cryptopia send email whenever deposit and withdrawal happen where the email include relevant transaction ID. Have you checked your emails?
Thanks for the tips.
I only have one withdrew email, an altcoin to a hard wallett which i dont have access to any longer. No idea why I do not have any information/emails on deposits to the account.
For reference, IIRC means "If i recall correctly", so i might be wrong and i can't check my own email history since sometimes i delete very old email that i think is useless.
