But as of the moment, frankly speaking the governments are not yet ready to use any crypto currencies as they have no control with and there are many hindrances that need to be fix first before it can be implemented. China is already in the move in developing their own currencies and once it will happen then more and more countries will surely launch their own currencies also. People are dependent to their respective governments so right now all of the decisions are on the government side if they will temporarily use a crypto to counter this virus or not.
The government will not be willing to use bitcoin for its payment method because bitcoin cannot be regulated, and the use of bitcoin, for the time being, does not contribute to the benefit of each country. Bitcoin is only a bridge between fiat and each country's digital currency. Bitcoin will be remembered in history as a forerunner to the creation of the digitalization of money. In the future, man will use digital money in each country where he lives, not bitcoin.
