I am participating in the referral program through Ferma. I registered, received a link in my personal account, and started sharing it on my blog. I brought in more than 20 people, and my percentage increased to 0.7. Payments come regularly: I have withdrawn to both a dollar account and cryptocurrency. The minimum withdrawal amount is small, around 3 dollars. I like that the earnings are transparent, and it's clear which operation the reward came from.
