I think prices will continue to decline over time, and the market is critically in need of new investors to recover asset prices, this is evident from the picture you show in this post,
In these days the price of bitcoin is almost constant. A little bit increase and on the next day decrease again. This situation lasts for the last 8 months. There is no growth in the price and I think in the future the price will continue the same. There would be no increase atleast till the end of this year. All predictions are just false and they have no reality. I wouldn't say no movement! As you can see bitcoin made a good growth from mid-July to early August, and also from mid-April to early may. Again, there were falls, it was necessary to open short positions. You can see for yourself what price range, and you could earn enough. If you mean a similar growth in December 2017, you will be waiting for it for a long time.
