I ask this because of the corona virus where people are too scared to hold money.
The issue is that we value btc against the usd and other fiat currencies. If fiat currencies were no longer how would bitcoin be valued...inflation etc? Can't get my head around how it would work.
It's impossible for bitcoin to become a world number one currency because every country already have their own currency which issued by the banks and their government. Also bitcoin is decentralize which is government don't want because they don't have full control on it.
