The first way is to place the entry or purchase in satoshis (whole) or in BTC at the top of the screen. If you place satoshis, for example 709500, Crypteris will format the value in BTC: 0.00709500.

By clicking on the calculator image, in the upper left, you will proceed to make the calculations from 1% to 50%, both in profit or loss. In the image above you see the gains. In the following the losses:
