It's an old thread but if someone is looking for the answer so be it. Finding networks that pay partners in Bitcoin is rather challenging.
There are definitely a few out there, but they may be harder to come by than networks that pay in traditional currencies. However, one platform that I can recommend is
https://merchant.cryptex.net/en. They have a great program that allows partners to earn Bitcoin by promoting their platform and getting other users to sign up. They also have a variety of options for earning crypto, such as watching ads and taking surveys. They have a user-friendly interface and you can withdraw your crypto earnings to your personal wallet easily.
Hope this helps! Let us know if you have any other questions.
