Just tried a few, and only made a few. So it's not really that profitable unless you know some a large group of people who can help you and make them use the platform. Even though people nowadays wants an easypeasy money, still they don't want to try those referral things as for the majority of them in the past only made a fake affiliates. So the efforts has been wasted and they only made the people looked dumb for advertising their platform for free.
