I write down how many coins I bought and the amount. When I want to calculate, I subtract the amount I bought from the current amount times the amount of coins. Then I add the answers and get the total.

Guys, I have a question. Is there a place where you can find out your real profit? For example: I bought USUAL at 0.60, and I contributed at 0.80, 1.10, 1.19... anyway... so I can't get an idea of ​​how much I invested and how much it appreciated. If anyone can give me a tip if Binance offers a report of this type, I would appreciate it.
