There are some ways to earn money without paicing bets and I would like to talk about some of them.
First and the main one is the affiliate/referal programas, this way by sharing your affiliate link you will get some incom from the users bets, isn't easy to get good affiliate (users who bet a lot) but with one high roller you could make a descent amount.
Affiliate referral programs in gambling is another way of making money from gambling but is not even as easy as we thought, because it requires you to have alot of users who will gamble using your referral link and this is not as easy as we thought. Infact there is no easy way to make money from gambling, the only way I have think may be easy is the aspect of owning a casino.
