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
Haha it's pretty nice sarcasm I must say. But you aren't lying for sure, a lot of people who use Cryptocurrencies don't actually use it for payments but even stablecoins aren't used a lot for payments too, they are used instead by traders to just maintain their capital when they are not trading other than that even stablecoins aren't being used much in payments these days but bitcoin is still far better as a payment option than other Cryptos of it's magnitude, it's just that market participants have entered into this market for quick gains.
