So in that way I think the people's economy will be helped, so in this way a country's economy can also be helped because the community invests in bitcoin.
what is my understanding like that, I ask for your opinion from all of you?
Bitcoin is for everyone freedom but it was not created to help governments fixing their loopholes in their central bank systems and their economies.
If they want, they can join and use their national treasuries to stack Bitcoin but if their economies are weak and vulnerable to global financial crashes and shocks, Bitcoin can not help.
Community are biggest power but if governments support Bitcoin, accept it as one of payment methods or better make it legal tender, it will be beneficial for their communities and citizens but again it won't help to avoid their economic crash from central banks.
