That tweet sounds like something I've heard before.  Didn't some politician make a proposal years ago for buying bitcoin in order to fix the Social Security problem that's inevitably going to happen? 

Whatever the case may be, any country buying bitcoin for any purpose (with taxpayers' dollars, I remind you) is extremely risky--and no matter how big a fan you or I may be of bitcoin, I don't think governments ought to be dabbling in it.  And not just because of the risk; it goes against everything bitcoin stands for.  I'm curious as to whether this story is going to be followed up on.
