After selling 9.8 bitcoins, the government owns 200K BTC.
Such words are used to scare people.
If the price goes down, the government will buy it later, so it is harassing people by spreading false news.
The government will buy back bitcoins because everyone wants to buy after selling.
As far as is known, the US government has never bought bitcoins. All the bitcoins that it owns have been
confiscated in recent years in the cases of Silk Road, Bitfinex and James Zhong. Of course, we know that a number of other states secretly accumulate bitcoins, but in this case we are talking about open data. And I don't remember the US government announcing plans to increase its share of bitcoin ownership.
