What is the margin on WhiteBIT?

Could you please elaborate on the concept of margin trading on WhiteBIT? I'm particularly interested in understanding the percentage of margin required by the platform for various types of trades. Is there a standard margin rate that applies across all trading pairs, or does it vary depending on the asset being traded? Additionally, are there any fees associated with margin trading on WhiteBIT that traders should be aware of? I'm looking for a comprehensive explanation to help me better understand the margin trading landscape on this platform.
