Well, people would have to find answers to why the bitcoin is rising and falling since every time the value fluctuates, there is not always reason to why we had such fluctuations, and you know that the value of bitcoin is not only dependent on the power of buying and selling or demand and supply, it could also depends on people mentality which is one of the trigger to acting on the buy or sell button.

I have seen so many people after Facebook announce their intention to lunch the coin initially without specific time frame start investing in bitcoin because of the believe and the mentality that this will be a trigger for the bitcoin bull run, and the coin itself might not be the trigger, but the action they took at that time to choose to buy is what actually may have led to the price increase and then they associate it to Facebook.
