Somehow I missed this post but broadly agree. Bitcoin is not anti-fragile but cryptocurrency as an "ecosystem" is. The more things that happen, good and bad, the better the overall system gets. Even though bad things 'suck' (like wallet hacks and frozen coins) the system learns from this and makes continual improvements. In the long run I see things improving.
I'm also a fan of Taleb's work and been following him for years. Haven't read his latest book yet.
