How do I buy coins on Bitget?

Could you please explain to me in detail how I can purchase coins on Bitget? I'm quite new to the cryptocurrency world and am a bit overwhelmed with all the options and processes involved. Could you guide me through the steps of setting up an account, depositing funds, and then finally making a purchase? I'd also like to know if there are any specific fees or charges that I should be aware of when using Bitget. Additionally, are there any safety measures or best practices that I should follow to ensure the security of my transactions and account? Thank you for your help in navigating this process.
