What is a fair percentage for affiliates?

I'm curious to know, what is considered a fair percentage for affiliates in the world of cryptocurrency and finance? Is there a standard rate that most businesses adhere to, or does it vary greatly depending on the nature of the partnership and the expected volume of traffic or conversions? As an affiliate partner, I want to ensure that I'm being compensated fairly for the efforts I put in to promote a product or service. Any insights you can provide would be greatly appreciated.
