Who needs to pay surcharge?

Excuse me, could you clarify who exactly needs to pay the surcharge? Is it applicable to all transactions involving cryptocurrency, or are there specific criteria that must be met? For instance, does the size of the transaction determine whether a surcharge is imposed, or is it based on the type of cryptocurrency being exchanged? Additionally, are there any exemptions or exceptions to this rule that I should be aware of? I'd appreciate any insight you can provide to help me better understand the surcharge policy.
