  Not sure if all crypto is a scam necessarily, but sure that world is chock full of scammers trying to out-scam each other.

It's all scams. Even if the coin itself is not a total scam, the exchanges do some of the most shady things you can imagine. They'll actively trade against their customers. They'll do insider trading, rugpull their customers, gets "hacked" by an insider and steal all your coins, etc.

Even BTC and ETH are shady. ETH should have been classified as security. BTC is an environmental disaster and centralized by a few large miners.
