Great work bitcoinparty_pl. I like the website. It's nice and simple to use.

Just a few observations. I don't see Coinbase Pro in the list of exchanges when I pick USD. That is where I make most of my purchases and sales, so quite a bummer not being able to compare the quotes there with other exchanges. And fees for Gemini look a bit off (unless it's showing Polish fees and not US fees, in which case I am probably wrong).

Also, is the amount that you show in "You'll receive" before or after the fees have been deducted?
