How much does CoinZoom charge?

Could you please elaborate on the fee structure imposed by CoinZoom? I'm particularly interested in understanding if there are any trading fees, deposit and withdrawal charges, or any other hidden costs associated with using their platform. Are the fees competitive within the cryptocurrency exchange industry? Additionally, does CoinZoom offer any fee discounts or promotions for high-volume traders or users who meet certain criteria? It would be helpful to have a comprehensive breakdown of their fee policy.
