What is the difference between BTCB and BTC?

Could you kindly elaborate on the key distinctions between BTCB and BTC? I'm particularly interested in understanding the technical and functional differences, as well as any implications they might have for investors and crypto enthusiasts. I've heard rumors about BTCB being a wrapped version of BTC, but I'd appreciate a more detailed explanation. Could you also discuss any potential risks or benefits associated with each of these cryptocurrencies? Thank you for taking the time to address my questions.
