It is a certainty that Bitcoin is volatile in nature how much it can go down or go up no one can confidently say with guarantee and assurance hence anyone has the liberty to speculate or predict the price of Bitcoin at any point in time perhaps that's another important aspect that makes the whole system very interesting, is it not funny how people make certain predictions that looks unrealistic?  But however it is what it is which of course we can't change it's nature of being a speculative asset, yes if Bitcoin falls to 3k a lot will lose focus but let's consider what could your personal decision rather than what others will do and surely not everyone will lose that confidence.
