It would be much better to play for something else. For example, for points.
How would points be any different, if in the end, it'll be converted into crypto or money? It'd basically be the same thing with extra steps. Also, some may argue gambling isn't just money obtained from nothing. It can be seen as a use of skill and observation that's being displayed to earn some money, while risking losing our money in the process.
In a sense, Gamblers have created their own value exchange system/marketplace where risk is the commodity.
You made a good suggestion which I would also like to agree with you on that, if those point will be converted to crypto currency when it gets matured then it's fine I think it will make more sense than this regular method we are using now, but if the point will be a liability I mean something that can't add any value to ones life then I would prefer going with this regular method than this one at least there's a chance of winning, losing, and having fun even though the wining will not come all the time but at least there's a chance of it happening maybe at anytime but since there's no guarantee I would Stick to having fun with it until when luck gets to me.
