If the bitcoin price goes down as it now does not need to panic, control your emotions, be patient and wait for bitcoin prices to rise again as bitcoin prices will surely rise again.
Yeah it has seen a lot of dumps but then price use to increase again at high level so they should not be worry about price. Holding is a way that big players use to play bitcoin, they invest and wait for price of bitcoin to grow again it is not good to sell at this time. Bitcoin rule is bought low and sell high, it is not good sell just accumulate. They buy panic but they dont sell at panic so holding is best option about bitcoin now I am willing to invest in bitcoin and for long time price of bitcoin will grow fast.
