Pick any group or interrest that is large enough and you'll find the same composition of different kinds of people. NPCs, scammers, criminals, silent geniuses, teachers, builders, opportunistic assholes etc. you get the point. Substitute the b-word with star-wars, philosophy, motorcycles, parenting, cosplay, flightsim whatever and your post funnily enough still mostly valid. This is applied tribalism, you're just happen to be in the bitxoin cave (on its birthday... 😅)
