If one day the demand for gold no longer exists, do you think it will still be valuable?
the chances of that happening are far closer to zero than the demand for bitcoin no longer existing. so why don't we just agree that your question is based on a faulty premise that the demand for gold could ever "no longer exist". As long as people exist, the demand for gold will exist. That's not the case with bitcoin. Read that sentence again!Quote
Also, you're claiming gold has uses because it's made into jewelry and used in certain industries...and bitcoin isn't?
gold is a byproduct of the universe. bitcoin is just a figment of our imagination. if all the computers went away, so would bitcoin. why do i even need to explain something like that though?

So the fact that we use bitcoin as a payment method, a store of value...that's not a use case or uses, what do you call that?
i call that something that can be replaced with something else. what can you replace gold with?Quote
Because bitcoin cannot be touched with hands nor can it be used for jewelry like gold, it is considered useless and has no use case. Is that true in a world gradually digitizing everything we live in?
the chances of bitcoin ending up worthless are far greater than gold very not having strong demand. make of that what you will.
