There are many concepts I don't know. Which I had to find out in order to understand your post (Futures, Market maker, volatility, liquidity, among others). 
As far as I understood Futures affect the price of Bitcoin, but only at the time they are created or expired (At the end of the month as you have indicated).
Cryptocurrency is much more behaviorally driven than traditional asset classes.
I do not understand this phrase, not all assets, included crypto, are propelled because of their behavior? 
Thank you for letting me know another reason that affects the volatility of Bitcoin.
I'll keep in touch
