Does MEXC charge interest?

Excuse me, I was just going through the MEXC platform and I had a question regarding their fee structure. Specifically, I was wondering if MEXC charges any kind of interest on the funds that users keep in their accounts? I'm particularly interested in knowing if there are any fees associated with holding cryptocurrencies or fiat currencies on the platform. It would be great if you could clarify this point for me. Thank you in advance for your assistance.
