I got involved with btc when it was in the single digits, the crowd was very different then - cryptoanarchists. So your call to "diversify your investments" sounds to me much more like "diversify your politics", which is obviously a silly thing to tell somebody - especially somebody whose politics is any anarcho flavor. While I can only speak for myself, I do think this is true for many others: I was already living pretty comfortably and a few million isn't enough of appreciably change one's quality of life as a software developer.
