Tell me a single useful real world use case that Ethereum is being used in today, a decade after its creation
If I can solve that problem with another simpler, older technology it doesn’t count as useful. I don’t care if you can pay for things using ethereum when I can just use my credit card instead.
if there was a real use case it would have manifested itself at this point
i think the abstraction needs to be much higher to end user for this stuff to have value. having to manage your own wallet doesn't make sense.
