"Crypto" is not a sign of decentralization, most coins these days rely on a small team of developers and their network designs tend to be heavily centralized.

Satoshi never used the word "cryptocurrency" or "crypto" (aside from cryptography). This word got invented when altcoins started emerging. And altcoins are like parasites, they don't like to call themselves altcoins, they call themselves crypto, because crypto means "Bitcoin + altcoins", and it's hard to criticize Bitcoin.

So, stopping calling Bitcoin "crypto" is a good idea, it would separate Bitcoin from alts.
