As per history, always western leads and rest are following
.
Due to higher literacy rate and readiness to adopt new things and more importantly modernized thinking, western people and government are marching forward always to new revolutions and this may continue in crypto adoptions too.
For example, when almost all the countries were silent or neural on bitcoins by 2014 after bitcoin peaked above $1000 for the first time, only few European countries opened their stand about cryptos like they declared that they will treat cryptos as asset whereas most eastern countries are not doing anything about cryptos even in 2019.
most economists say that fiat is a scam or a lie as the central banks are selling people a promise we will pay them back.
Yes, it is a lie with the hope of infinite "hand-over" among citizens so that never need to pay back.
fiat came in when it was needed to help solve the issues of carrying heavy gold for big transactions but now we have bitcoin there seems to be no other real use for it once bitcoin gets adopted by the masses.
For the exact same reason on-which fiat replaced gold, now it is time for bitcoin to replace fiat. History repeats itself.
