There are some persons that time the trading market by predicting the movement, once they notice a particular pattern the market is trending towards, they will quickly say it will remain down or it will rise. So people do make predictions, but it's also advised for you not to rely only on what some other persons have predicted, it is also good for you to do your own findings and map out a pattern that will work out for you. Before you start trading the Bitcoin market, you have to first educate yourself on how the market is traded.
