@happy9z:
You need to enter your BTC purchase as well in order to calculate the gain.
Right now it looks like you sold 1.99995106 BTC without ever buying them, which leads to this red warning.

@SteelHead:
The upgrade price is based on USD.
If the BTC price changes, the price on CT will change automatically.
But I will add more decimal places to the price soon, in order to make changes easier to track.

Best,
