If Bitcoin becomes a kind of digital gold, not for small transactions, but as storage of value, the price can reach as high as $ 10,000 or more.
Bitcoiners don't want to admit it, but it's primary use has been exactly that for years now. No one is out there buying hundreds of thousands of $$$ in bitcoin just so they can have unlimited number of coffee purchases in the future.
It wouldn't even matter if transaction fees came back down to $0. People still won't be buying coffees and croissants with bitcoin. Too much work, easier to use fiat debit cards, esp. when the fiat purchasing value is falling virtually every day. Why would I want to waste my bitcoin on a cup of coffee when I have fiat?
Again, the community can be ridiculously disingenuous to what is actually happening with Bitcoin now and in the future.
