now lets imagine world without fiat currency.
lets say we use bitcoins.
so milk price how many btc? fuel price? rent ? and how the prices will calculated?
and if there is only limited supply of bitcoins.....then those who who have bitcoins merely will rule over others?
so your skills or value in society dont count only matters who go the most of the bitcoins?
bitcoin halving by the time so less and less btc will be in circleation....so how the world will remain sustaineble then ?
okay if bitcoin is not good to be currency then ethereum ?? well ethereum is centralised as i know ?
stable currenies?? well i dont see point of them they are just the 1:1 of the same fiat currrencies.
so where does the theory come from then we go all in cryptocurrency and fiat currency will disapere?
well this is not possible bitcoin without fiat can not serve all the peoples currecny needs !!
right now we dont have clear answere so fiat currency still rules. how we are going to control the money supply how big quantity of currency is in circelation?
if bitcoin is the future of money without fiat then everybody will have the guns and shoot each other:D just to get other bitcoins becouse btc has limited supply lol

so i want to know if fiat currency will disapere then how the new currency will be issued? and how it will be backed?
