The choices made by the larger traders in pushing the market one direction or the other. I think the news stories that appear help to drive the herd along with these original choices. I wouldn't be convinced that we are on a new leg up unless it pushes on past $9,500

The reason why the bitcoin price are changing it's  a supply and demand, we knows that the value of bitcoin are very volatile and it is hard to know if it's continuing to increase because sometimes it will dropping her price. And yes the negative news will may affect the bitcoin price but it will recovery.

The main factor of the price is the news. I think the bad news is the reason for reaching this price now, but the support and resistance levels also have some effect

I think the most important factor affecting the price of bitcoin is media report.Whe there is a negative report or speculation by the media,prices usually drop even within 24 hours,people are much easily swayed by what the media says than with any technical analysis or new projects competing with btc.To a large extent,the last dips were caused by fb,twitter and google.Even if government issues a statement about btc,if there is no negative report by media,prices wont crash that much

What influences the price of bitcoin in the cryptocurrency market is the communication, the advertising on the web, the press sites talk about bitcoin as well as other co-altcoins. In addition, the supply and demand of investors in the cryptocurrency market also affect the price of bitcoin. Therefore, if you are a smart  you can take the best opportunity.

The answer is "We". We are the one responsible for the different aspects of bitcoin which also includes the changes in bitcoin prices. Many times it happens that we push bitcoin too hard and off limits and then the alternation in the prices happens. For example, consider the cases when bitcoin naturally dropping in its value then people get panic about it and they get so nervous that they cant even hold their breath for a minute and think about the whole situation and immediately start selling everything they have got. This makes the market situation even worst and thus bitcoin loses itself. In same manner prices increases too. I mean when they are done selling everything they have got then they will start thinking that Oh! Its good time to buy the coins and thus in the long they put more money and become responsible for the price rise.

Volatility is caused by huge supply and demand, fueled by emotions and fear of losing. Also since the futures entered the game market is highly manipulated. I am expecting another huge bull run once ETFs enter the game.

From my own finding I think negative speculation aka FUD is whats causing the price to drop drastically

but after this Easter holiday I have seen the price recover after this period but let us not get ahead of ourselves and expect a $10k rebound so fast because if that happens it will drop fast too, we need an organic price movement.

I think that most affect the price of Bitcoin is bad news. because when there is bad news about Bitcoin, the old investors are selling their coins so the coins are abundant and the price is cheap. and for new investors who want to invest by buying coins not so because there is bad news.

In my own point of view, the reason why the price of bitcoin dumps dramatically these days is because of banning of bitcoin in other countries that the number of bitcoin users are starting to decrease that will affect to its price. I think the reason why pther countries banned bitcoin is because they are afraid that bitcoin will replace everything.
