There are several really good documentaries on Amazon prime, netflix etc.  They explain some of the history of crypto, the current banking system, and even go into individual pssychologies during the up and down roller coaster of bitcoin.  The best and most important advice from all the learning and what everyone promotes is to just HODL during the downswings and BUY on the DIPS.

Seriously if you just take those two things and think long term your investments willl be solid
Learn as much as you can about blockchain tech, fundamentals of investing, but really just keep  HODLING long term
