I am sure you're aware that your $$ come from somewhere. Net positive for them? Not so much.
Ethereum is valued at $x,xxx per token because of the belief that more and more dApps will launch on it and everyone who uses them will have to buy Ethereum.
Uniswap's UNI is valued at $x per token because of the belief that once there is regulatory clarity, UNI holders will get a % of the revenue generated by Uniswap (currently over $100M/year).
These are basically startups with tokens. Some of them will go bust. Some of them will take years to monetize. Some will be profitable within a year.
As far as I can see there's no real equivalent for cryptocurrency - some crypto orgs notionally have revenues, but they always come from speculators or other crypto orgs (and, sure, maybe some drug dealers or capital control evaders, but that's a tiny fraction of the funding). Money goes into the crypto system and nothing of value comes out.
