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.
Definitely a good way to get your extra peanuts. I think that it takes so much more effort to get good leads so getting people to do the hard work for you via affiliate links is worth its weight in gold and I can see why companies love to do that. For every dollar you make they make 10 probably or something like that.
