Not wrong. Obviously there are lots of smart people into Bitcoin and nostr. Perhaps less obviously there are a lot of people in these groups who are paleo/keto/ketovore/carnivore/low-carb or otherwise interested in lifestyles that make their brain, emotions, and body work better.
Honestly the connection is significant and quite intriguing.
I'm a middle aged dude with a dad bod, but I went carnivore about 5 months ago to improve my metabolic health, and the mental and physical changes have been truly impressive and are still compounding.
