For 2017, I think bitcoin will be more popular as people discovers the benefits of BTC. Especially in helping people who doesn't have work earn money anywhere they are. And also it helps students to earn money for their school or family purposes.
Bitcoin will still going to experience the Ups and Downs this year, since it is very volatile, I mean its price, it will be easier to manipulate by this whales and I'm afraid on what will going to happen on August 1st, there is this news that bitcoin would going to split because of SegWit. I don't know if this is true, but I'm hoping that it would never happen.
