How do I transfer money to Bitget?

Excuse me, I'm a bit confused about transferring funds to Bitget. Could you please elaborate on the process for me? I'm specifically wondering about the steps I need to take to initiate the transfer, whether there are any fees involved, and if there are any security measures I should be aware of to ensure the safety of my transaction. Additionally, is there a specific time frame for when the funds would be available in my Bitget account after initiating the transfer? Thank you for your assistance.
