How to sell crypto to a bank account?

I'm curious, can you walk me through the process of selling cryptocurrency and transferring the proceeds to a bank account? I'm new to this and want to make sure I understand all the steps involved. Specifically, I'm wondering about the fees associated with the transaction, the time it takes for the funds to appear in my bank account, and any potential risks or challenges I should be aware of. I'd appreciate your guidance on how to navigate this process smoothly and securely.
