The government will try to gain control of it. From my own point of view, if you have a bitcoin in your wallet after five years, you may be a millionaire or otherwise but with bitcoin d being prrlesently prone it shows a brighter future. You know the bitcoin price in January 2017 is just $ 1000 and January 2018 is about $ 10,000. Even some crypto currencies have good potential like bitcoin, they are Ethereum, Litecoin, Anchors and Waves.
