Bitcoin is a virtual currency and it is not be stable its price might be goes down and also its will increase. It is Bitcoin's behaviour that it change its price.
that is right so no matter the price is up or down, as long as we don't panic about this, I think everything will be under control and we could still trade without worried. we have to seen this in the bitcoin journey and maybe in the future, the volatility will happen in every time and for now, I think we only need to follow where the price wants to go. just enjoy the ride and try to make a profit if you can and avoid listening for the bad news that will only make us getting panic.
