The more people who want it the more the value will grow. Bitcoin has not hit the main population yet. Until that happens I see a continually increasing value over time. There will be dips and peaks but the trend should be up.
Right now though the demand is not high enough to push the price even further. But for me, at the current price, it is still very good and one of the best investment that you can find. Although others wanted it to move into the $20K range, this year will not be that year. The main reason is that there are a lot of negativity right now and the bulls are still outside, observing what will happened to the market. So don't expect too much this year so that you won't be disappointed at the end.
