I think even if they do, they wouldn't succeed. Just look at the other countries who already banned Bitcoin, still there are a lot of people who are using it. The main idea behind bitcoin is to create a currency free from government and banks, and this is something that we want. For as long as we have internet, we can use bitcoin anytime, anywhere! Nah, how can they destroy something that's giving people the opportunity to earn the legal way and making our life more convenient?
