Be ready and aware that 2018 is the year of regulatory reckoning. Countries around the world are trying to determine how they are going to treat cryptocurrencies. Securities and Exchanges Commission (SEC) has halted several ICOs and hinted at the need for greater crypto regulation.
I am into cryptocurrency because of freedom, I can't deny to myself that I have worries regarding this issue. And as an investor, I really have no choice but to stay with crypto once the governments around the world have control to cryptocurrencies (if that became possible).
So as much as we can, also invest with physical properties with what you've earned. For we don't know what will happen next with our money in the digital world.
This is not an advice. It's simply a shared idea.
How about you? What do you have in mind?

It is impossible that government manage bitcoin, because bitcoin is a decentrallized currency no one owns it or operates it only the user who use it. But for example government manage bitcoin, it doesnt mean that government can fully manage bitcoin. BUt they can emplement a rules and it has a cause and effect to us. Maybe the first rules they implement is paying taxes. If the government manage bitcoin they can minimize the scammer and hackers.
