I became a constant listener of your videos a few weeks ago. Great insights and always interesting to get your thoughts.
Great to get an insight why you haven't selected steem into your top 5. Listening to your video today that was the first question which came to my mind because of your selection criteria: technology (steem is live for a long time and has proven its technology I guess), utility - here it seems steem would also be utilized even in a crash. Even though through reduced rewards user base might gets reduced.
In my opinion coins that "survive a crash" need to have the fundamentals right and be able to get through a bear market of 1-2 years. Being susceptible to major crashes seems to me more a short term argument not so relevant for long term survival of a bear market. Or what is for you "surviving a crash" - are you thinking more of a short/mid term crash of several month?
