I imagine Countries all over the world adopting a national strategy with BTC,
I don't see that happening anytime soon or ever.
On the part of the citizens; adoption of Bitcoin does not benefit the economy, neither does it help with creating an enabling environment for businesses to function. They can access it without it being a legal tender and with more freedom.
With governments is basically the same thing, they do not better their economy by adopting Bitcoin and it will always remain a secondary means of processing payments.
Adoption slightly helps Bitcoin with gaining acceptance, but that has a threshold to which it can be beneficial.
