If everyone in the world gets into crypto and cryptocurrency will become an official global currency, do you think bitcoin then will stop depending on fiat currency? Or will it just co-exist with fiat?
If the world only using bitcoin, i think it will be not safe because bitcoin price is often to fluctuates in the market.
But later in the future, maybe everyone start to using cryptocurrency only, fiat currency is not usable.
Cryptocurrency has been created in 2009, it is just only almost 10 years. Need more time i think.
