Why does BTC group think they don’t count as crypto?

Afraid of getting post nuked if I posted there.

Why do BTC maxis think BTC isn’t crypto? To my mind, It’s like people saying “oh no, I invest in gold, not minerals.”

My current assumption is that they’re just trying to draw arbitrary distinctions to separate them from small projects. I’m hoping there’s a better reason than made-up superiority, and hoping the folks here can fill me in!

My background: I own ETH and BTC. Not a whale, but a significant enough amount that I’ll state here I don’t need scam messages ;). Respect to people who do enough research to know what’s up with smaller coins, but that’s not something I have the time to focus on. I’ve been trading (mostly buying) crypto since 2016, so I’m not a newb, but tech isn’t my forte, so I’m not an expert.
