The anonymity of Bitcoin is a major feature of Bitcoin. If we transfer money, we cannot find out who the other party is.
Or we simply don't know the name of the other party.
It's hard for me to call it Bitcoin Anonymous considering the definition of Anonymous.
Seems Anonymous is used only for someone who whose name is unknown, which is completely fine/ok in "Crypto" space.
Besides, Bitcoin has a name (Name: Bitcoin) but it's not a person
So we could simply say it's Anonymity Friendly or users can be anonymous.
