Same story every time. At 1$ it was a bubble, at 30$ it was a bubble, at 100$, at 1000$, etc. I wonder what needs to happen for the "bubble" people to say - alright, this is not a bubble anymore, I was wrong. Or it will always be a bubble for them?
Fiat currencies are the opposite - inflation encourages spending because the money slowly trends towards being worthless if you don't spend or invest.
Fyi
