I did a trade with someone who wanted to empty their paypal account. They offered 1% premium in my favour.
Turns out PayPal will take 1% from my incoming payment. So the 1% premium covered that... But also PayPal also took a 1% fee from the sender which I don't see in my records.
So they're double dipping when someone sends money between PayPal accounts. Maybe it was because it was US to UK but 🤷♂️.
The bitcoin transfer was much smoother of course.
