I think understanding bitcoin will boost the mindset of investors.
I don't think someone who understands bitcoin that it is a currency that is not stable and come across bitcoin dip will panic to his/bitcoin because of bear market.  Whosoever understand bitcoin and  well prepared for it will never feel panic when bitcoin is in the bear market.
 Cryto market is unpredictable,  so sometimes the level at which it goes dip some people don't expect or prepare for it because they never had understanding for it. People should get good understanding before investing bitcoin,  that can only be what boost the mindset.
