Bitcoin's future is brilliant. But 2017 was a bit of a hurdle. The SEC decision had some negative impact on the issue bitcoin, such as the hard fork issue.
But since bitcoin is a very robust system, the price has come back to normal values. At the beginning of 2017, I thought that the price of bitcoin would be $ 2000 at the end of the year.
But I'm not sure right now. Negative news can cause the price to fall. At worst, I think it will be $ 1500 at the end of the year.
