The Dollar is so influential globally because of petrol and not because of US hegemony or consumer choice. This was the case for quite some time but the Petro-Dollar is not what it used to be anymore. There are quite a few competing players on the field now and how long petrol holds on to is a question of a few forseable years.Yes, we can all choose to spend in Crypto but if it is still being converted to fiat at the back -end then nothing will change in regards to crypto given value though fiat.

Crypto should find it's own petrol so to speak. A commodity or service that everybody needs which is priced primarily by crypto. Or wait for the Petro-Dollar to collapse and someone with big enough balls to introducea new commodity-Currency pairing to the world
