So I concluded they charge a hidden spread exchange fee. Do you know how many percentage is this fee?
I found a local innovative digital bank in my country which claims to not charge fees, but they have the spread thing feature, and informs it stays around 1%. So, technically, absence of fees is a fake propaganda, anyway.
EDIT: nevermind, although they don't display the fees and respective values charged on the moment of each operation, there is table informing the percentages.
