How much money do I need for copy trading?

I'm interested in copy trading as a way to invest in cryptocurrency, but I'm unsure about the initial investment required. Can you explain how much money I need to get started with copy trading? Is there a minimum amount that I need to deposit, or can I start with a smaller amount and gradually increase my investment over time? Additionally, are there any fees associated with copy trading that I should be aware of? I'd appreciate any insights you can provide on this topic.
