As I had encountered that day by day more people are joining bitcoin inspite of its sky rocketing price and day by day more and more government and other agencies are coming against bitcoin so will bitcoin stay alive and will it be able to invite new user in the network?
I do not see government and agencies coming against Bitcoin because if they do, they had trackdown all nodes and shutdown any possible bitcoin operation like mining farm or store that accept bitcoin.
Governments will become the biggest holders of bitcoin, and manipulate it like they do with gold. A central bank can buy bitcoin or gold at ANY price: they print the money for it, buy it, and consider that they have printed only that amount of money they have an underlying asset against: the coins themselves. Exactly as they do with gold. Bitcoin will become the central banker's pump of value from "bitcoin investors" into their hands, exactly as they do with gold.
Moreover, with bitcoin, they know exactly where the coins are and can follow all transactions.
I wouldn't be surprised if the Chinese government is actually taking in most of the chinese exchange's wallets. That's a big amount of bitcoin they'd offer themselves.
