Is There a Difference Between Patreon and Buy Me a Copy?

You can only get Super Chat and different things like that for now if you're in the YouTube Partner Program. But with Buy Me a Copy, you could still collect donation from your community. You don't have to be in YouTube Partner Program to do that. There are a bunch of different physical product ideas that you can do as a creator. If you have an idea, no matter how novel it may seem, if you feel like it can make money...you can generate revenue.
