How to unwrap WBTC?

Could you please elaborate on the process of unwrapping WBTC? I'm curious to know the steps involved, as well as any potential risks or considerations I should be aware of before proceeding. Could you also explain the reasons why someone might want to unwrap WBTC, and what benefits they might gain from doing so? Additionally, I'd like to know if there are any fees associated with the unwrapping process, and if so, how much they typically are. Thank you for your assistance in clarifying this matter.
