He definitely does. Funny tweet too.

Crypto is a scam. Only Bitcoin matters.
Yes? Nothing in GG's tweet implies otherwise.
He said Bitcoin started crypto. I contend that scammers started crypto. Only Bitcoin matters. 
I think he's not wrong. Bitcoin, paradoxically, inspired crypto (and CBDC).
Wasn't Satoshi the first shitcoiner?
Sure, I guess. Seems like semantics to me. Without Bitcoin there would be no crypto scams, so I think it's accurate (though not precise) to say Bitcoin started crypto. Regardless, he seems to understand that there is a difference between Bitcoin and crypto, based on his rhetoric and actions as SEC chair. He also taught a class at MIT on Bitcoin from a technological perspective.
