Bitcoin will not an because it crypto-currency. We can use this really illegally. No matter if your government ban this currency. That will be the beginning of death bitcoin if it really happened.
My country is a bitcoin-prohibited, but there are still a lot of people who invest bitcoin, so I think maybe the country's ban on bitcoin will affect its price and development, but it will not kill bitcoin unless it is forbidden in the world , But now there are already countries that accept bitcoin.
