which causes bitcoin prices to fall is a issue of negative issues in the news. and lack of supply and demand. this is what causes bitcoin prices to fall. but you do not need to panic because it will be back to stable again.
Yeah you are right. False news are the main reason for fall in the price. I dont understand why some people give such nonsense statements to devalue bitcoin in the market and want people to withdraw their money from bitcoin. Some illiterate people believe in such statements and sell their bitcoin no matter what the price is and when the investment cap decreases the price will automatically decrease.
