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

Bitcoin is affecting the economy of the country and if government think that it will be bad for their own economy then they have no choice but to shutdown cryptocurrency in order for their country to survive.
perhaps the regulations they develop are against their value. besides, there may be internal factors that make bitcoin getting banned. actually bitcoin can be very beneficial to a society if the government also supports it.
