I think bitcoin will not distrupt economies because that transition from fiat money to crypto will not be so fast and also while this transition will be happening, there will be transition among institutions as well.
Maybe you're right in you're country,but the other country is against of bitcoin currency in their economy.many investor and business will bankrupt if that government is no response for this btc transaction specially for taxes.well,also in my country bitcoin is not totally accepted. But they have no control to each person that want to get rich soon.
