The last I checked, there is only a supply of 450 BTC per day. So, this selling will equate to a bit under half a year worth of it. In any case, a few years into the future people will look upon the US for selling their BTC the same way that we look at Canada and the UK now for selling off their gold reserves at market lows.... and now so disparately wish we had those bars to defend the dollar. (But it's too costly now, lol). These were terrible decisions. There is an old saying here, when it comes to western governments... "Can't fix stupid."
