What is the funding fee in Bitget?

Could you please elaborate on the funding fee structure in Bitget? As a cryptocurrency trader, I'm curious to understand how this fee is calculated and how it affects my trading activities. Is the funding fee a fixed amount or does it vary based on certain factors such as the market conditions or the asset I'm trading? Additionally, how often are the funding fees charged, and are there any strategies I can employ to minimize this cost? I'd appreciate any insights you could provide on this matter.
