On January 19th, 2021, the CryptoTrader.Tax team completed a database migration that will serve as a more robust engine for matching small-cap cryptocurrencies with their historical USD pricing data.
If you logged back into your CryptoTrader.Tax account after 1/19/21 and saw this Action Required modal, it is because certain assets that you had previously imported were not recognizable to the system.
To move forward with your tax report, simply map your coins to their true cryptocurrency ticker, or delete them altogether.
For many early users of CryptoTrader.Tax, it is likely that these un-mapped tickers are a result of user error when typing in the asset ticker symbol for a given coin.
