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.
Bitcoin need not to be ready because this is a material to be use and always in the availabilities .
What you need to asked is the people like us,are we ready to use Bitcoin as single currency?can this be applicable in our daily usage? can Bitcoin be use in all merchants?
the answer is NO,we can't even use this in Groceries in many countries and even in many countries Bitcoin is banned so how will the world use this when this was not even recognized by some governments.
we need more time and education first before the world finally use this but will never happen to be a single currency ,Fiat will remain and many countries will stay that way though they will allow Bitcoin to circulate in their country.
