As a trend indead Bitcoin has really show it's potential value, as in case of society currently are about to change which will automatically make both investors and government agencies to change their currency into Bitcoin inorder to safe guard their money it is a note that there are every probability that in time to come cryptocurrency will be officially adopted so I encourage everyone to go into cryptocurrency either in terms of trading or investment.
I personally doubt government agencies would adopt Bitcoin in general, perhaps they could use Bitcoin or Monero in order to finance some of their undercover operations, but in general, since those agencies are an arm of a centralized system then it would not make much sense for them to encourage their self-destruction.
Each sovereign nation (in most of the cases) stands to protect their FIAT and it is unlikely that will change in the near future.
