Bitcoin Technical Analysis 15/01/19: Sharp Rise Indicates Near-Term Reversal 

Recently, the price of Bitcoin increased almost to 5%, which was caused by the serious rise of some recent updates. 

This rise could signal the beginning of a reversal back to 4,000, however, it is not that possible, unless it comes back to the 3800 support level, at least. 

The reversal shows that some wealthy investors could buy a large amount of Bitcoin. When somebody is intended to purchase a large amount of any cryptocurrency (in this case Bitcoin) and there aren't enough people who sell at the same time, a person does not have an opportunity to have the whole amount he or she wants. That is why this person has to make a purchase twice. 

If it is directly connected with the reversal case seen recently, there's still a chance that the price will drop back. You should control all the changes and stay updated about new developments.
