Absolutely love CoinTracking! It's my go to recommendation when anyone asks for tracking/tax software. Quick question...

Do you plan on adding CFT (Coss Fee Token) to the database? It's a new token that has the same utility as BNB, except it's on Coss.io, not Binance. Like I said, I'm a big supporter of CoinTracking and I'm trying to get the Coss community onboard but the biggest reservation right now is the lack of CFT coverage. Since CFT is used for trading fee discounts, all the trades from Coss will be erroneous when imported to CoinTracking until CFT is added. 

What is happening with USDC? It has been the coinbase stablecoin and reflected at $1 in my account for weeks, but it is now showing a price of $1.30. I believe it's seeing a different coin with the same ticker.

What is the correct symbol for USDC on Coinbase to use?

Thanks Dominik
It is almost clear for me - so if sell amount of coins higher than I've bought it I'll get a negative balance, Am I right?

And one more question, please
Is it possible to have different types of portfolios in one account? I'll explain I'm asking about.
For example I'd like to have 3 types of portfolios - Hold, Trade, etc. I will make different transactions with the coins within this portfolios,
and I'd like to have different statistic for each portfolio for each coin in this portfolio. Now we can group transactions, but amount would be shown together.
