This a story from a long time ago. But whenever a country ban crypto currency, then the people of that country will immedietly sell off thier holdings increasing the supply of coins in the market and plummeting the price in effect. That is always a bad news for all of us. But I'm pretty sure people will pick it up since it's so cheap.
Even the china will ban bitcoins in their country still I think that people there will hold BTCs there because if the government is unaware about the fame and popularity of BTCs, I am sure the people wouldnt act like that because they know about a well and secure future of BTCs ahead. And if they become panic and sell out their BTCs, I know people all over the world would instantly buy them.
