Btc main use case now is this:
Bitcoin is good market prices indicator to show just wich way all other coins likely will go.
If there is another reasons to use ....its unlikely.
People say specially traders that btc price is good indicator also to show wich way altcoins might go.
For payments and moving funds the stablecoins are definately best ones.
But yeah..now we know btc main usecase
That is what you think and not for general meaning i respect your views but this wasn't really a thing.
you did not even mentioned about the Medium of exchanging that totally bitcoin is what all about and you did not even bother to say how useful bitcoin in any areas?
you are a bitter crypto user that hates bitcoin and a altcoin supporter .
