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 Does your friends don't even know the actual situations of the crpto coins right now most of them were dropping and like bitcoin, altcoins is also volatile same as bitcoin character. So no reasons to panic at all and whether you prefer bitcoin or altcoins holding, they're still a good partners in profit making with cypto currencies. Even price will fall down, being panic is not the right actions and all I can say is be brave and face the challenging moments when the price feared to go down. Its a normal part of trading and I am confident enough that after the big fall, the price will be rising so fast and will hit the biggest price ever in the future.
