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's funny you say that, because one of my best friends asked me in mid-2017 if he should buy Bitcoin (After walking past one my many mining rigs in my house lol). He said "I want to invest a few grand, but I feel like I missed the boat."He said that to me again a week ago, and then I told him his current holdings would be worth double what he invested in early 2017; oh and I also told him my mining operation is bringing in almost as much money as my (lucrative) day job. He just went "FUCK! What am I doing?!"
I still don't think he has bought any...
