Referral bonuses or earnings arent something that you could rely nor expect into because not all people or users who registers under your name are big depositors or players which means it would really be just normal that you wont really gain something if those users arent playing.
I beg to differ. I know many people who make a living out of referral programs and they have made it their main job.
You need to know where to promote your ref links (choose your audience) and how to promote it to get the best results. Sometimes, you even need to invest some money for paid ads before you can start earning.
If you are into streaming or have a big blog/group/channel then better opt for affiliate programs than ref programs.
You will probably have to believe.

Although I cant imagine how it is possible to earn normally doing only this type of activity? Probably, in order for the earnings to be substantial and to allow them to live, have housing, a car and other benefits of civilization, such a person must spend all his time at the computer. 24/7. And yet the environment where it works must be absolutely computerized and receptive to referral programs. I have a hard time imagining how this works? Probably all the same, the main income goes to such a person from other types of activities on the Internet. And not only from participation in referral programs.
And of course, this can not work effectively all over the world.
Well, maybe in Silicon Valley and it works, of course
