This is a sign that digital currency mainstream adoption is being consolidated. But once the governments start to use digital currencies won't they make their own digital currency instead of adopting bitcoin?
Why make there own when Bitcoin is already built and used all over the world.
Also the UK could easily buy all bitcoins as its worth 3.3b right now which is not much for a whole country.
The issued digital currency is centralized and cannot be compared with bitcoin. I don't think they will buy bitcoin. Bitcoin is spreat to many ppl and it is difficulty for them to control it.
