It's possible I'm 100% wrong but I don't recall him having billionaire level security in any pics I've seen.
Unless they're extremely low key. He usually seems to be by himself and/or with his girl.
Fred.
He probably has security, but I remember in one of those interviews he did with Nore, Nore said he was concerned about him moving around with no security, and Kanye said something along the lines of his security could set him up and he trusts no one more than himself.
He basically if something were to happen to him while moving dolo, it is what it is.
