As I have seen this already too many times since past few years, I believe it would be beneficial to share my experience with crypto markets. Do not sell your coins/tokens when the market is dropping, it's just a pure speculation and perhaps market manipulation from whales who only target to earn on whatever the price moves they can achieve. If you're reasonable, sell when market is high and buyer/hold when market is bleeding. I hope this helps you to decide 
It is right. I, too, keep all my tokens received from the bounty of companies and my crypto. I do not want to lose my profit. Bitcoin's rise last year meanwhile led to increasing amounts of interest in other digital currencies. Now bitcoin is growing and with it, and other coins. I'm glad that was patient.
