I'm not sure that term simply means, to hold no coin in a portfolio. I've seen it defined as simply beleving crypto will fail, but I've also seen the harshist critics who do show some technical understanding (clearly with a different conclusion, and maybe not always fairly presenting that technical understanding) embrace that term.
I think there are people who just have different priorities, and people who are simply coming of age to participate in any investment. 130 million people born 18 years ago. Some of the them will have died, but if you divide that by 365, you are still talking about well over 300,000 turning 18 every day worldwide. These labels, meaning simply, too stupid, or sour, or general belief it will fail, completely disregards that cylindrical truth, or maybe condemns, predicts, or even wishes for that number to be ever dwindling. To put 300k people a day in a category along side “a cabal of permanent in-house critics” is stupider than most of those 130 million people who happen to be dumb ass modern teenagers. It’s really no wonder why they recoil at this relatively young culture digging it’s heals into the ground.
