How do I deposit money into my Tether account?

Hello, I'm interested in depositing money into my Tether account, but I'm not quite sure how to proceed. Could you please guide me through the steps? I've heard that Tether is a stablecoin, which means its value is pegged to the US dollar. However, I'm not sure if this affects the deposit process. I also have a few questions about the security of my funds once they're deposited. Could you explain how Tether ensures the safety of its users' money? Additionally, are there any fees associated with depositing money into a Tether account? I'd appreciate any clarifications and advice you can provide. Thank you.
