Another Schelling point example (AI is good at these actually).

Crypto = Cryptocurrency.
That is what people mean when they use this word. They don't mean "only the shitty currencies except Bitcoin".
Words are a Schelling point and their meaning is emergent of how they are used. We might not like it, but trying to redefine how people use the words is useless.
Bitcoin is a cryptocurrency. Probably the best example of a cryptocurrency, in short crypto.
But yes - you can say "Bitcoin, not crypto (in general)" as in "I focus on Bitcoin, not the whole category, because I think other cryptocurrencies are horseshit". You should not say "Bitcoin is not crypto", because it is, it is what people mean by the word crypto (=cryptocurrencies) and Bitcoin is a perfect example of a cryptocurrency.
