"People were also skeptical of paper money when it displaced gold"

Well... Yes of course they were. Because 'paper money' Fiat currency. DOESN'T Work.

Atleast crypto is backed by a cap on amount of coins.
Paper money has nothing backing its value. It will be inflated to the moon until its worthless.
Fiat currency always fails. Always has done in its entire history. Just a matter of time.
Great post :)
