Gerontocracy? What a load of crap.
I'm older than both Larry Fink and Jamie Dimon and I clued in immediately upon hearing about Bitcoin. Now I'm set for life. One of my friends, a member of the Silent Generation in his 80s, accumulated 13BTC before passing away over a year ago. When he knew the end was drawing near, he went on a sending spree and cashed in his last coins a week before he died. He had no heirs.
Meanwhile, a Millennial friend scoffed at me and called me a sucker who couldn't see through an obvious scam, while pursuing a "career" as an online poker player.
Another Millennial friend had the brains to hop aboard in 2013. We attended Vitalik Buterin's shitcoin white paper unveiling together at Decentral in January 2014. Needless to say we both took a pass.
My wife is Gen-X and regrets not getting in when she heard about it (before me!) in 2012. She needed the money for another enterprise.
Bitcoin may have been developed by mostly Gen-Xers (and some Boomers) but it crosses generational lines. It's not about age.
Besides their age, what do Buffett, Fink and Dimon have in common? They all have an interest in the status quo, specifically the legacy financial system.
It wasn't a cataclysmic event that extincted the dinosaurs. It was their failure to adapt to it. Many older species survived.
