>On the other hand I could create 21M cryptocoins on a blockchain (calling them Bitcoin2 or even just Bitcoin if it pleases). I can make them function identically, similarly or more efficiently than Bitcoin. I can create a new blockchain (network) or put these coins on an existing blockchain (say the Ethereum blockchain). How much would you pay for all 21M Bitcoin? How much would you pay me to create you 21M Bitcoin2 and transfer 100% of them to you?
Econ 101: The price of a currency is based on people's trust in that currency.
>The real irony is cryptocoins and blockchains couldn't even exist without gold, because it is a necessary component in the machines that created bitcoin, that hosts blockchain nodes, mines, hosts wallets and facilitates transactions.
That's not irony. Thats a happy coincidence.
