Stay calm and  never get panic. That is just natural to experience ups and down once you get involve in a business. We can't say that bitcoin always rising because there is a movement of price anytime. We never know when is the exact time of its getting fall or rise, we never even tell its exact price in advance. Just keep in mind that you are not the only person who trusted BTC. There are so many people waiting for it rise more so nothng to worry about.
