How do I transfer Bitcoin to a bank account?

Could you please elaborate on the process of transferring Bitcoin to a bank account? I'm a bit unclear on the steps involved and the potential risks or limitations I may encounter. Could you break it down step-by-step? Additionally, I'd like to know if there are any fees associated with this process and how long it typically takes for the funds to reach my bank account. I'm also curious about the security measures involved and whether there are any recommended platforms or services that you'd advise me to use. Your insight and guidance in this matter would be greatly appreciated.
