I have an ERC-20 token (Telcoin) that I bought in 2018 which was reissued in 2020. The old tokens now have no value. At the moment Koinly shows that I have twice the amount of the new token than I originally had. Is there a way to differentiate or some kind of label that could indicate that the old token has been voided for the new one?
Hoping someone can help thanks!
