When more country give support for blockchain technology, I guess that will be a great time to see bitcoin and altcoin will start the mass adoption and in that time, all people will try to learn about blockchain technology, how they can take the benefits from the cryptocurrency, how they can use cryptocurrency for making a transaction, and many else.
Each government will give their permission for their citizen to try to make money from cryptocurrency, and the government will make a regulation for cryptocurrency and who knows, the government will create their own crypto too.
The possibilities to see many countries supporting blockchain technology will be wide open, and it's on the way to go there, and it might happen in the next years.
Actually these governments are interested in blockchain technology and not bitcoin itself. I believe they plan creating their own currencies to benefit themselves from crypto currency, but continuing with the benefits of centralization at same time.
I'm not sure how positive it will be for bitcoin and decentralized altcoins when these countries start adopting blockchain technology. It can be very bad for crypto users, as some regulations are very restrictive, like those in China and India.
