this, ride the wave and get off when your in the green.

I think it's an interesting proof of concept, but the overwhelming portion of it's value is derived from it's usefulness as a vehicle for fraud, and not prospective business value.

I think I understand

what I don't get about dapps is that, from what I understand, every thing you do on your smart contract code costs gas. So for example if I have some app or game built on it, how can the user do simple things like changing the settings of something without having to pay money every single time?

Well game on bc (at least more than simple one) is not really blockchain usecase is it?
And its dumb idea.

That's why you see only gambling daps (decentralisation, easy transfer of value, low fees, anonymity, smart contract is public and inmutable bla bla=is good usecase for them).

Smartcontracts, NFT-s (underrated imho), STO-s (now ico scams are over) on other hand are..
