I did the same faults like several guys before, I didnt upgrade the contract but sent my old contract coins to cryptopia, they replied to me, please help me Ethbits team, thanks very very much.
Cryptopia has upgraded to the new version. You will need to talk to the ETB team to see what is required to get your ETB back. Their contact details are in the above blog.
Just explain to them that you sent ETB to Cryptopia using the old contract and they should be able to help. They have our contact details if they need to get in touch with us.
