I know that everyone gets excited when the price is increasing but you should probably think about this twice, those who don't have bitcoin yet, should probably wait a little bit more before buying, just to see how things will go in the upcoming hours/days and as for those who already have bitcoin, If you're hodler and you actually can afford to lose whatever you have then just continue to hodl otherwise, you may think about selling. In the meantime, I suggest reading the

That is indeed true. Bitcoin's market value is going insane. But the thing that matters here is that it gives profit to its users and investors as its price becomes more expensive and the expectations of its price to be higher in te future is what excites its users and investors and gives them reason to hold and invest more which indeed seems to a good idea.
