It's called gambling because it's not money. Money have stable value so you can exchnage thing. Exhcenging things and then (((somoene))) inflates or deflates value is called usury.

I wouldn't necessarily say money has stable value (particularly for some shithole countries) but it's certainly more stable than crypto.
Currently all countries since "winning" ww2 use "fiat" which is controlled by jewish Fed. Which is usury layer. Meaning we don't even have money today.
