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.
Seems you're new to gambling marketing. I'm yet to see a marketer in this your discretion that doesn't gamble. Most of them create groups and show winning tickets from successive gambling wins and some even offer free bets to get people's attention. Posting random links would get you almost no client because of the high alert on casino scams.
The second one is the VIP programas, like the one that stake offers, you need to bet to grow your account, but once you have a good VIP level you will get a weekly and monthly prizes, It will be better if you bet that month but even without betting you will get something each week/month.
This approach just contradicted your topic, you've owned to betting to build your account to VIP level and if you know what's VIP, you'll know they're even the ones that bet more and to qualify for those prizes you must meet several conditions as a VIP member, not just by doing nothing. No way you can fool the casino bro
