The very moment the main industry starts adopting cryptocurrencies will be the moment when we can say the mainstream has adopted. Governments do not like cryptocurrencies, as we do can do business without their supervision and knowing. When the industry accept cryptocurrencies, the government will be forced to act along with it. We do have one benefit, the industry business men I have spoken to about this subject are very enthousiastic about cryptocurrencies, due to it being decentralized. So everybody, talk about it on your own work, start locally, that way we can increase awareness on a global level! :D
