No one can answer you regarding the rise of bitcoin in the next coming days. We have to understand that bitcoin price is very unstable and anything can happen on the price in just a matter of minutes. And even though buying and holding bitcoin over the long haul is a great strategy, sometimes its better to sell if:

1. You need money for emergency
2. You think that the price could do down
3. You have better investment or other opportunities that you are going to seek

If you can answer that simple question then I guess you have the decision to either wait or cash it out now when the price is really high. Its really up to you mate.
