When btc falls even 1% in price, alts react 10 times 'mostly' on that move and lose much more. You have invested in alts or btc? As observed, btc too got hit by a dip of more than 5% in a day which may have been caused due to high fees, US Dollar got strong or whales manipulating it to let Turkish people buy it cheap. It is not possible to find the reasons behind these dips and even pumps except when someone comes ahead and takes the responsibility of the same. Oh yes, may be it got dipped in because it was bloody Monday, and we may see this dip become larger in size.
