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. Government might be trying to regulate Bitcoin exchanges but there is no way this government is preventing people from mining or doing transaction with Bitcoin. As for the adopters, it will always have new comers especially governments all over the world are starting to recognize Bitcoin as legal tender or payment one by one.
