Hello, Here's how to add a purchase price to a token on Waltio:

Move your mouse over the indicated price of the token concerned, then click on "Add".

You can now indicate the average purchase price of your token, in my case for BTC it's 10,000 EUR.

Waltio calculates your P&L, which is now displayed in the last column:

My capital gain is therefore €31.79 on today's date.

Adding a purchase price in "Portfolio" does not change the data in the tax report, as the calculation is not the same.

The Waltio team.
