The FUD is the real factor for the price of bitcoin to fall down because without the FUDs in the internet then people will not believed to the false information or fake news in the market but that is just normal and we should get used to that because that is how the game works in terms of the cryptocurrency market and we cannot change that but we can adjust to it.
FUD is an important reason that is true but for example in my opinion the last crash was not caused by FUD, the price would have gone down on its own regardless of external factors since it was impossible to maintain such a high price, so in that case the crash was just caused by the greed of new investors wanting to get fast profits out of this market.
