If we assume that Bitcoin somehow managed to become money (which is unrealistic), it will destroy the fiat currency according to the scenario that I described in
my previous postI went and checked that thread
Bitcoin could only destroy fiat in "your own imagination". You basically assume that the fiat currency would depreciate due to increases in money velocity, but how can it increase if people won't be spending their bitcoins? In other words, you set up mutually exclusive initial conditions, i.e. explicitly asserting that people will hoard bitcoins and implicitly assuming they are going to spend them. Then you proceed to draw impossible conclusions, which is Bitcoin destroying fiat
We cannot apply Gresham’s law because we do not have good money and bad money and we do not have legal tender (or any other ways to set an equal nominal value). We only have money and Bitcoin
It's ironic that you yourself appeal to "good old" Gresham’s Law in your first post. How come?
