On a more serious note, selling or holding is a personal decision and you shouldn't follow the advice of others (so whether or not the majority wants to sell, you'll still need to make your own decision).
If you plan on holding bitcoin you should consider a couple of factors;
• Have a trading strategy, this helps investors balance profit and loss
• Only invest what you can afford to lose, as you very well could lose them
• Do not get too emotionally invested. This is a Bitcoin forum and majority here are maximalists, but only follow the fundamentals of the network, and avoid bias when choosing an investment.
