Does Binance sell real Bitcoin?

Hello there, I have a question about Binance and the nature of Bitcoin they sell. I've heard that Binance is a popular cryptocurrency exchange, but I'm wondering if the Bitcoin they offer is genuine and authentic. Can you clarify whether Binance sells real Bitcoin, or if there's any risk of encountering fake or fraudulent transactions when using their platform? Additionally, what measures does Binance take to ensure the authenticity and security of the Bitcoin they facilitate? I'd appreciate any information you can provide on this matter. Thank you.
