Is 3% a high foreign transaction fee?

As someone looking to engage in international financial transactions involving cryptocurrency, I am curious to know: does a 3% foreign transaction fee generally qualify as a high charge, particularly in comparison to other available options within the crypto sphere? Could you elaborate on what factors typically influence the determination of a 'high' fee in this context, and whether there are any common practices or industry standards that I should be aware of when evaluating different service providers?
