The bull market is already here, but in the long term. The investment in BTC made in 2016 is about +2000% so its stil very bullish. Short term fluctuations are purely speculative and those trends are impossible to predict. If you own about 2000 BTC you can make market pressure and influence the price.
BTC is very sensitive to manipulation and many big players are doing it. If you are not one of them its much better to step aside or they will crush you. Find your own bay, move across the sidelines and leave the playing field for the big guys.
