What is the average merchant services processing fee?

Could you please clarify for me what the average merchant services processing fee typically entails in the realm of cryptocurrency and finance? I'm interested in understanding the general range of fees that merchants might encounter when processing transactions using this method. Are there any specific factors that influence the processing fee, such as the type of cryptocurrency being used or the volume of transactions? Additionally, how does this compare to traditional payment processing fees? Thank you for your insights.
