On the one hand, I think that the negative news and FUD from the media impact on the price of bitcoin. In fact, taking into account that there are powerful financial groups behind these mass media, I think that these newses have the intention of making the bitcoin price drops so these groups can buy bitcoin at a lower price. On the other hand, during the rally of the last year we could see some negative news from China and other countries that didn't have any effect on the price of bitcoin, so I don't know if the influence of media on the price of bitcoin is real or not.
Another things I see causing the drop of Bitcoin price Stability of the Bitcoin Network: Stability of the bitcoin network is a major factor that most bitcoin enthusiasts are concerned about. Most people want a secure network where they will not lose their money. Unlike the conventional currencies like euros and dollars, bitcoins are largely perceived as economic bubbles as they are only valuable when exchanged with other currencies, but do not have any inherent value on their own. If most people and business organizations stopped accepting bitcoins, the “bubble” would burst, leading to a fall in the bitcoin price.
The Bitcoin Demand and Supply: The price of bitcoins is largely depended on the demand and supply. This means that high demand and low supply often leads to an increase in the price. Note that bitcoins have a controlled supply whereby the total number of bitcoins in circulation must never be more than 21 million. Due to the limited supply, there are speculations that the bitcoin price will continue to rise with time.
