I think that it was really strange that in January when BTC went down all big cryptocurrency exchanges closed registration for new members and they opened it only when the price was low. Then at spring when the downtrend was broken(7000$) there were many news that cryptocurrency now will go up! But whales just made big shorts at 10 000 $and all the news said that cryptocurrency won't go up for along time and market went down to current position.
I don't think that but I will say that price is partly manipulated with the news that are going on, usually those news are affecting the price positively or negatively, and there are some people who are creating news.
