How do I buy new coins in Binance?

As a cryptocurrency enthusiast, I'm interested in purchasing new coins through Binance, but I'm a bit confused about the process. Could you walk me through the steps? Firstly, I'd like to know how to set up an account on Binance and ensure that it's secure. Then, I'd like to understand how to deposit funds into my account, whether it's through fiat currency or another cryptocurrency. Once my funds are in, I'm curious about finding the specific coin I want to buy and executing the trade. Additionally, I'd like to know if there are any fees involved and how to keep track of my portfolio's performance. Lastly, I'm interested in learning about any safety measures or tips to ensure a smooth and secure trading experience. Thank you for your assistance.
