is not that bitcoin able to change the state of its users which effects also on the state of the country's economy, why even banned hemzzz

It is easy, there are some countries who do not allow bitcoin in there, just like China, they want to have everything under their control, even the communications, they are 100% centralized, and why do you think that they will allow Bitcoins and cryptos in there? Of course not.
Exactly like that, but to think not at all. As long as bitcoin runs the through the community softly and warming it won't be banned . But if bitcoin will used as diversion for some illegal movements then it Will be band by the government.
