I think this is all because of increasing numbers of bitcoin haters that keeps on demotivating other people also to not to invest into bitcoin and bitcoin haters are increasing because of neglectance of governments of many countries regarding bitcoin that they are completely against of bitcoin and also demotivating people of their countries not to use bitcoin and this could be the most probable reason why people are not investing into bitcoin and thus in turn the valuation is deflating and the market of bitcoin is falling.
