How do I transfer crypto to bank account instantly?

I'm curious about the process of transferring cryptocurrency to a bank account as quickly as possible. Can you walk me through the steps involved in doing so? Are there any specific platforms or services that allow for instant transfers, or is it a more lengthy process that requires waiting for blockchain confirmations? Are there any fees associated with this type of transfer, and if so, how do they compare to other methods of converting crypto to cash? Lastly, are there any security considerations I should be aware of when making this type of transaction?
