The assumptions here are:

1. USD fails

2. All the other currencies are "dying"

3. (let's say) Monero exists and is not dying

So yes in the scenario you've constructed where everything but a cryptocurrency dies or is dying, crypto is more successful.

You misread - the scenario is that USD is dying, but other state currencies like Euro or JPY stay afloat.

Ok then in that case everyone flocks to the other reserve currencies for all normal goods and services and crypto remains the primary means of exchange on the Ape JPEG market
