I think that's threat from government over anybody that is using bitcoin, because i know very well if country is hundred percent (%100) populated, at list fifty percent (%50) is aware of cryptocurrency and definitely they are using it, so is not possible for government of a country block her citizens Bank account because they are using bitcoin, i think it's impossible and it can't happen.
As said, it can be considered as a threat. The government is elected to do the people's need. Even when they're making policies, they should take the people into account. Everything have got positive and negative side.
A government should act wisely favouring the people. As mentioned, a government/bank blocking ones bank account for using bitcoin will make the user find an alternate way to use cryptocurrencies. Why to make people go for it, better is to regulate and support the necessity of technology.
Have you ever seen a government in your entire life that considers only the good of the people? I mean even in a situation where they do something good, that is usually means they either got bribed to do that, or they want to get votes for doing that. I have never seen any political party, any politician in any nation that did something good just because they want the people of that nation to be doing better.
This is why I believe that anything related to banks, or crypto, or any financial situation will not be regulated based on what would be the best for general population, it would be based on how they could enrich themselves and get more powerful. This is why I lost hope for regular financial fiat world and got into crypto, because I know that I could be right but justice system would defend banks against me even if they are 100% guaranteed wrong, why? Because I am not powerful and they are.
