I agree with your view. When looking at Bitcoin, look at the most recent pullbacks. We experienced a 20% drop in value easily. While such drops are not uncommon, a 20% drop can be substantial and may overwhelm an individual’s ability to hold on and wait for a recovery. 

Everybody is different, but I know personally I would rather keep a certain percentage in Bitcoin. Keep with the allocation I feel comfortable with and diversify.

I also feel that bitcoin will do much better than other investments. 
But it doesnt hurt to diversity a small portion into something that you can liquidate quickly without worrying about it. 
Liquidating bitcoin might hurt if the market is down at that time.
