i agree that the referrals commissions are sometimes a lot more than what you can earn yourself but also you have to make a lot of efforts to find those referrals and be lucky enough to find at least one high roller so that your commissions are a decent amount.
That is safe but I don't think we can earn a good amount of money from the referral program of a gambling sites, I have been a member for four gambling sites dice and sports book but until now I have not earn a good amount of money from the referral program. That is safe but not enough to make you happy.
it depends on how you are advertising your referral link and where you are doing it. you can't expect gaining referrals if you are not willing to properly advertise it.
if you want to gather good number of affiliates that are spending money too, you have to advertise it on bitcointalk (cause it is bitcoin gambling related) and also on other forums (which are related to gambling) you an make blogs, website or banner advertising to gather these affiliates.
money doesn't come to your easily!Referral links are highly frowned upon here in the forum, just so you know. That is if you're going to be advertising publicly it just as is, without any taste. It's okay if you do it on your signature and on private messages.
Also, the best way to get referrals is to actually offer them help when they join under your name, like a group or something. With that, they can expand exponentially and you'll just be sitting there getting shares from your referrals.
