How to deposit money in Bitrue?

Can you please explain in detail how to deposit money into Bitrue? I'm new to the platform and would like to know the step-by-step process to ensure a smooth and secure transaction. Is there a specific currency that's preferred for deposits? Also, do I need to have a wallet already set up or can I create one directly on Bitrue? Lastly, what are the fees associated with depositing funds, and how long does it usually take for the deposit to reflect in my account?
