The only way bitcoin could realistically die
It dies simply from having garbage fundamentals compared to physical metals. As I already explained, there is no plausible outcome Bitcoin becomes the world reserve currency. None:
• More fungible than metals
• More divisible than metals
• More portable than metals
• More storable than metals
• More tradeable than metals (In fact you can trade the good itself across the world and not some "ticket" for the good)
• More bearable than metals (You can "hold" it rather than holding some "ticket" to a safe in which the metal may or may not be)
• More spendable than metals. (Try getting change on a stick of gum from a bar of gold)
• More durable than metals (Try recovering your gold bar that sank to the bottom of the sea, got raided, took a detour during delivery or otherwise went AWOL. Bitcoin private keys are decoupled from the asset that enables redundant storage while the world's most powerful computing network looks after your public keys. With gold, the private and public keys are welded together making such sophistication impossible)
Bitcoin only has "garbage" fundamentals in the way that synthetic antibiotics have "garbage fundamentals" compared to garlic. But feel free to chomp on 20 raw cloves of garlic per day the next time you get tonsillitis.
It doesn't matter. What matters is the fundamentals relative to the prevailing market platform which over the last 150 years has been electronic. States and central banks invest in gold because they have to, not because it has "better fundamentals". It's regulated tier 1 capital. They can also benefit from a 1% change in the gold price whereas that gain on the average joe's savings would just about get you a dinner for one
