I don’t mind there being an emoji for cryptocurrency. It’s a relevant thing in modern society whether we like it or not, so there’s no reason it should be excluded. But just not Bitcoin, specifically. Even though Bitcoin is the one that kicked off crypto, it’s still a brand name, which would result in auto-rejection according to the Unicode Consortium’s guidelines.

If there was a more general-purpose icon/symbol that could represent cryptocurrency in general, that’d be more appropriate. But it can’t be Bitcoin.
