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.
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.
Telegram, Twitter and other social media platforms are a good way to generate income in gambling without betting. For example, on Chips, they offer random deposit to people who guess for example, what slots are shown on the blurred image, they give some money to people who reply their twitter post with screenshot of win, they send some spins to random people who comment on their twitters and so on. I think, this is a very good way to earn without betting.
Affiliate programs are very good for those who can be socially active and record videos or make podcasts every 3 days or every week but you need some investment. If you want to build a website, then you'll need lots of money and free time because the competition is very high, there is a website casino guru that has tens of people employed to run the business, so, your best bet is social media like TikTok and Youtube.
