What's the percentage they are charging?

I am not using them anymore since 2019. But at that time it was roughly 3 to 4.5%.

I am still using Skrill, they charge 1.45%. They were charging 2%, but after the popularity of crypto, they reduced it to 1.45%.

Ouch! 3 to 4.5% is a bit much.
Glad there are alternatives!
