This article explains what you need to do if a coin, which was previously not supported by cryptact and you uploaded the trade history using a custom coin, became supported.
Example: Last year, I participated in the ICO for ZKP. We did not support ZKP at the time, so I created a custom coin (USER-ZKP) and uploaded the history via a custom file.
This year, we started supporting ZKP. Now, there are two separate coins that both refer to the same coin. What should I do?
HOW TO HANDLE THE ABOVE SCENARIO
There are two separate coins that both refer to the same coin. They need to be unified into one.
On the Ledger tab, click the relevant custom trade to open its transaction detail. Edit the Base Currency to the appropriate supported currency (in this case ZKP) and Commit.
