How to use BitPay for beginners?

Hello there, I'm curious about BitPay and how it works for beginners. Could you please explain in simple terms how I can get started using BitPay to make payments and receive cryptocurrency? I'm a bit new to this world of cryptocurrency and I'm eager to learn more. What are the steps involved in setting up an account, connecting it to my bank, and making transactions? Also, is there a fee associated with using BitPay and how does it compare to traditional payment methods? Thank you for your help!
