I'm on the fence about it. Gov't tends to trash anything it touches. But, I'm not sure the world will have the confidence in BTC necessary for mass adoption until some big players get involved. The FUD is still strong.
I want every shop owner to accept bitcoin, but there is still a lot of risk involved. Risk that pushes bitcoin to the fringes for development and use. I'm all about DIY, cypherpunk tech, but we need normies to get to scale.
Gov'ts buying it is a clear signal of normalization. That's something I look forward to.
