I doubt governments scared of BTC. If you ask me the Blockchain and a global currency is what is important for governments and Btc and crypto is evolving that platform for them. a One world government is not something thats going to happen overnight but Blockchain sure is the vehicle for it. People still talk about Btc as decentralized ore anonymous ,but you have to KYC and what else to Trade or move . In reality its s is more centralized and doubtful that trying to hide your transactions or  avoid taxes will get you anywhere but in trouble. There is already chips to implant under skin and blockchain as a currency with each person assigned a address as per KYC will amount to absolute control over the public. Its coming guys and what happens to BTC and Crypto is quite obvious just the when is anybodys guess.Thinking that Btc will replace fiat is plain daft,imagine any government accepting a currency not their own,never happen BUT a crypto like currency of their own design based on the blockchain model that is so diligently being developed as open source projects will come to be eventually. Very possibly they even started the self financing open source project to get their pbrainchild developed and tested  for free. Many people sing btc as a saviour of the poor and unbanked but in reality its the vehicle of true enslavement that they promote purely for self enrichment. At this time crypto steals more money and time from the poor not even talking about the blatant frauds in all aspects of crypto. Spending vast hours in faucets for cents per day,dealing with uderhanded play at every turn,even if they get that money eventually new pitfalls await . making money is for those holding the exchanges and those few holding vast amount but obviously not controlling the price or even worried about selling it for fiat at any time ya right.
