I'm not a fan of blockchain games yet. They have nothing interesting yet. Opportunity to earn? Well, so myself. I will not say that this way of spending time will bring profit. And interest? Well, in a snake, you can play on nokia 3310. And it will be much more epic.
Well at first maybe you will not appreciate blockchain games but if you will try just a few games, I can say that it is worth is. Besides, blockchain games is created to entertain the customer. If you want to have some profit, talk to the devs and project manager.
