Yes, one day in the future we will find a use for bitcoin finally. It has been 15 years and we still don't have a really great use case for it but it will happen.
Sure there are plenty of use cases but no real significant traction for the everyday consumer. Price fluctuation is wild, would hate to have this has a "currency" that I hold to pay the bills. Even ignoring the volitility, the transaction costs historically have been high enough that it is not attractive from the consumer lens. Not FUD.
