Panic selling is what draws the price of Bitcoin so down to the drain. Any event which leads to panic selling of Bitcoin can be considered as a contributing factor. The news of a hacked exchange site, false news from governments, banks and the media, a Bitcoin advocate country later banning Bitcoins etc. All these factors contribute to the fall in price of Bitcoin on the market.
Many analysts and analyses are pointing towards good news and bad news or image of any product or about any product will directly affect value of that product.
But I think that it is actually demand rate that may reduce or increase with bad or good news respectively but the most prominent statement is to mention demand rate. The current price shows stability and this came as a result of the gap that has reduced between up and down movement.
There's a lot of reason which case bitcoin fall down. one of the big reason is spearing the wrong information and make peoples mind to left bitcoins.
Wrong information or news is just part of the market and the reaction of each and every one to it, will only be dependent on how they are able to verify every news, but I would not say that is the main problem for a fall in price here as that could only just be one of the few little catalyst but not the major one.
The major one is the fact that this is a speculative space and a lot of people do not even understand what they are getting into as they just do things blindly. Look at the FOMO last year, the market got out of hand with an unsustainable demand, and then just like that, the whales started cashing out. That is basically just how I saw it.
There is a big problem associated with fake news. One, it affects the good face of bitcoin and spoil it. Second, it destroys the trust factor of users and investors. They start losing their interest and faith so ultimately they start selling it. Definitely when you have invested your money in something, you must not be so careless about it. You have to take care of every risk associated with it.
