Bitcoin doesn't need permission or prohibition by regulatory authorities (of a particular country or countries), because it is decentralized in nature. Here, the factor influencing the bitcoin price is more the news background associated with the regulation it, and not the regulation itself and the actions of users (holders) of bitcoin. If they panicked after the ban in N-country and started selling btc, then this ban will indirectly affect the value of the BTC-price. It would seem that this is all nonsense, but it happens.
