That doesn’t explain Bitcoin’s price. Even if what you say is true, assuming BTC gets cracked within 2-3 years, smart money would get out of it and would go into real estate, land and physical assets instead. Why isn’t this happening? I mean anyone who is able to graso exponentials and there are a LOT of people who can, will come to same realization.

Also, you can’t really switch Bitcoin to quantum-proof algo. It’s pretty much inpossible.
