I think the people who say bitcoin is going to 10/100k or some other silly number are just as ridiculous as the bitcoin is dead people. Both never offer anything as to why it going to either die or go to the moon. Nobody can predict where bitcoin is going. Sure, it could become worth tens of thousands but it could also become worthless. We can only wait and see.
here a few things to consider why BTC tech has value
Quantitative Easing:
No Capital controls
Jurisdictional arbitrage
Individual sovereign wealth
also the byszantine generals problem that BTC sovles (to a large extent) is paradigm shifting.
the wealth is backed quite a bit just by that.
Fiat and everything else before it a order of magnitude or more removed from the implications and operation of BTC tech.
