Why in some countries Bitcoin is banned is the accepting of Bitcoin by websites and that are illegal .
Nahhh, it's not really banned, it's just not recommended as an a mode of payment, because we all know that until now, bitcoin is not legalize by many countries. But not totally banned.
What are you talking about. Have you heard of this country called Russia? Well they banned Bitcoin and it is illegal to use it in Russia. Banned means banned. Not just, "not recommended".
