The next step for bitcoin is just to be recognized as a global currency all over the world , the next thing is that governments officially accept it as a currency that all the world knows about and that the users and traders number have exponentially increased in parallel as it's value did over this year !
2017 is bitcoin's year without any doubt , and like many speculated , the 1 million dollar per coin isn't a fantasy any more and i'm sure that no matter correction or hard fork that'll happen , it wouldn't affect bitcoin as those previous ones did and it's getting harder and harder to shut it down !
To be accepted by the government is not as easy as 1, 2, 3. It could be, yes, someday but not now. Centralized banking or the government behind will be frighten enough to make a mess about bitcoin (I hope they won't,). Haha.
