do you believe with bitcoin in the future can replace fiat as a number one currency?
Nah,i dont think bitcoin can ever replace fiat because even though we believe so much in bitcoins but you need to accept the fact that not everyone is aware of bitcoins,like poor people.they just know about fiat in thier country
Bitcoin still need much development in order to replace fiat but it's impossible to happen. It will take many many years. Rather than thinking bitcoin to replace the fiat, be contented to what bitcoin can do today.
