You can check clickbank, digistore24, etc CPA networks. They have some crypto products that you can try selling and earn good commissions.
You are the 1st case I have seen opposite way. Many of affiliate marketers have an idea on monetizing the traffic/emails and what they don't have is user data!
In your case, it's opposite. You have a great number of data, but not sure of monetizing it. Better go with JV , you will make a lot without working hard because you have your part done, it's your JV partner who needs to work hard to convert now
