Why do I keep getting charged a monthly maintenance fee?

Hello there, I'm curious to understand why I'm continually being charged a monthly maintenance fee for my cryptocurrency account. Could you please explain the reasoning behind this fee? Is it a standard practice in the industry, or is it specific to your platform? Additionally, what services does this fee cover, and are there any ways to avoid or reduce this cost? I'd appreciate any clarification you can provide to help me better understand this aspect of my cryptocurrency management.
