It would be silly for central banks to not be accumulating some Bitcoin just in case. They understand how money works..
The Government as a whole entity may not have invested or investing in Bitcoin secretly BUT believe you men that elite politicians have been in the game for a while now. Using the decentralized nature of Bitcoin to amass wealth and move their cash around as they wish.
Exactly, the government has excellent people, who may be the ones who always give opinions about the bans on Bitcoin but they also own Bitcoins. No fool would ignore the great benefits of Bitcoin because they ever realized that Bitcoin was massive.
