Why in some countries Bitcoin is banned is the accepting of Bitcoin by websites and that are illegal .
Some countries banned bitcoin like Israel is becsuse of using bitcoin in illegal activity. Yet, banning bitcoin in a country doesn't mean can not be use totally. Some uses proxy in order to operate that. Hence, banning bitcoin in a country can't stop people to top using it.
I think prohibit the use bitcoin bitcoin will not kill, after all, the government will not be able to block the bitcoin, users will be able to easily access bitcoin as long as they have internet, but I hope the government can at least allow bitcoin
