I'm searching a website where I can promote link (paid to promote). I'll register as your referrer.
The easiest way to make money by promoting Bitcoin is affiliate program. For the beginning, try faucets - each faucet has a referral program. You'll find plenty of them in the "Micro earnings" section:

yeah, but that's kinda worthless.
I'm still waiting for some company to develop a udemi or clickbank for crypto
In this way, you gain experience, and then you can make money in many other affiliate programs. From what I know, the best earnings are due casino affiliate programs.
It is easy to find a lot of them (casinos) in "Marketplace" -->"Gambling" section
