I think you do not need to panic with bitcoin prices .. up and down, that's normal. You should pay attention to the news about the falling bitcoin .. it will make you panic .. you must be optimistic bitcoin will return to normal point and price will go up. if you look at bitcoin prices from year to year always experience a significant change and up until now .. maybe if you invest in the last year .. now you become rich with bitcoin you.
That is what I am trying to explain to most of my friends. They are still new in the cryptocurrency and they are scared about the volatile of the bitcoin price. Well, some of them do not believe in what I said and they sold all of their bitcoin to save their money 
And soon, they regreted about what they had done. Therefore, there is nothing need to be worried when you see the bitcoin price falls down
