Probably, the governments do not want to recognize digital currencies and wants to eliminate them, Because they cannot control them. Moreover, because of these currencies, there is a crisis if many banks and the high value of currencies adversely affect the economy of countries, especially with the rise of users cryptocurrencies.
In addition to that, I guess that in the future, the governments will recognize all cyrptocurrencies (particularly if it cannot eliminate them) to exploit financial profits but this may happen, but certainly on conditions.
That's the problem the government always wanted to have conditions where they will benefits instead of thinking of adopting this system
to be more useful for their payment transactions, if only those who in power realized how crypto can help the financial society then it can
be utilize for the benefits of both sides.
