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 post by theymos on Reddit, very useful.
