I think it is just government strategy to avoid having people's freedom in moving their money because they can't find a way to manipulate money in the bitcoin and because they know that they can get nothing from this. Maybe giving their community false news about Bitcoin didn't work so they are doing another option. Since a lot says that this wasn't an official announcement, maybe this is just also a part of the fake news circulating in the crypto world made by those who want to take down Bitcoin.
