What is the monthly fixed management fee?

Could you please clarify what the monthly fixed management fee entails? I understand it's a regular charge associated with managing a cryptocurrency portfolio or fund, but I'm curious about the specifics. For instance, does it cover a certain range of services or is it a flat rate regardless of the size of the investment? Additionally, are there any hidden fees or charges that I should be aware of beyond this monthly fee? Understanding these details will help me make an informed decision about whether this fee structure aligns with my investment goals and expectations.
