Not in the nearest future. Governments are fighting against cryptos. China is banning everything, Europe rejects Libra to take place, USA wants to ban TON and so on. We still have a long long way towards the mass adoption.
The reason why governments don't want to accept crypto in the economy because they can't control it. We can't blaim gov. by of banning crypto in their county.
Maybe in the near future they will accept it but they'll impose tax so that the economy of the nation benefit on crypto.
If Government adopts Cryptos, people who worked in banks will loose their jobs. Our government will run out of money without getting tax. They cant get separate money for Intentional transactions. Banks will be closed... They need another 10 years to educate people about cryptos... People in slum and uneducated will be in trouble.
I didn't regret if banks will be closed, those banks is the reason why poor stay poor because they impose unfair amount of interest.
We don't should implement of total digital currency use, we still need our own fiat currency in case we don't have our devices to perform transactions buying, selling on our daily needs.
Mass adoption is great but we still need our fiat currency.
The big question is do we have any government now that can implement this, this is not easy, you need all people educated and there are areas that can be transacted with fiat only because not all part of any country has the features of a city, only a highly industrialized country can do this.
