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.
I think I understand your point, and I agree that the points system is also part of the value itself, which will ultimately be exchanged according to its own rate (depending on the game provider using the points system).
Gambling is about wagering value, meaning anything which has value can be wagered, whether it is goods, Bitcoin, or crypto, and others. However, sometimes this requires converting, as part of the rules in a particular game provider.
Therefore, regardless of the gambling system or scheme used, we should consider gambling as a form of entertainment only, and any winnings should be considered an additional reward, or additional entertainment. So, we must remain responsible gamblers, be wise in our actions, and always limit ourselves from excessive gambling. Esentially, excessive is bad in anything, including in gambling.
