now there are some countries that began to issue a ban on the use of bitcoin, is there any influence on the country and of course its users in economic value?
The government see bitcoin as a problem in the economy, but the truth is the government don't want bitcoin users to earn money without paying any taxes and they cannot control bitcoin and blockchain technology because it is decentralized, that is why they chose to banned bitcoin.
Totally in agreement with this point, the government is interested only in the exclusive profit for them, it is a way to have control, if the people in a nation manage to generate better income with bitcoin, they begin to free themselves little by little from an economic system where they demand a lot of rules and sometimes labor exploitation arises.
