"The Collapse of Fiat Currency," is in itself a huge topic. I think the predictions in this post would come true if all fiat currencies collapsed in a matter of months.

This isn't quite how currency collapse works though. There is a contagion factor when currencies are pegged to others but that peg isn't permanent.

The sudden collapse of fiat currencies around the world would most likely kill every kind of crypto. But that would also kill so much else that worries about the value of crypto currency would be very far from our minds.

A slow collapse of fiat around the world though is the very thing crypto needs and from what I'm seeing, the slow collapse of fiat is well underway.

Negative interest rates are a boon to all crypto.
