How much do resellers make?

I'm curious to know, how much profit can resellers typically expect to make in the world of cryptocurrency and finance? Is there a general range or formula that can be applied, or does it depend heavily on factors like market conditions, the specific cryptocurrency being traded, and the reseller's own strategies and expertise? Are there any tips or strategies that you, as a professional practitioner in this field, would recommend to someone looking to become a successful reseller?
