$BTC $ETH

Maybe some of you know and can explain what exactly determines the price of Bitcoin and what it is needed for?

Right now it costs 92,000, and for that money, you could buy a good car or an apartment in some city.

Why buy a useless coin that is not used and takes two hours to reach the recipient? There is USDT for that and a bunch of other coins that arrive in seconds.

And in general, it is just a number on the screen.

Or am I still wrong?
