Ethereum has a value equal to roughly GM, Ford and Toyota combined. Probably as much as AWS despite the fact that no large company I know of runs their company on Ethereum. The largest things on Ethereum are things like Uniswap which facilities speculation on Ethereum...hehe. What happens to the world if Ethereum disappears? I don't think it misses much of a beat. Ethereum does have "tons of uses and potential"...but it's still just that, and it could be displaced.
