How much does it cost to list on CoinMarketCap?

I'm curious, could you possibly explain how much it costs to list a cryptocurrency on CoinMarketCap? I've noticed various projects being listed there and it seems like a crucial step for gaining exposure in the crypto space. I'm wondering if it's a cost-effective marketing strategy or if there are hidden expenses that might not be immediately apparent. Additionally, are there any requirements or qualifications that a project needs to meet in order to be considered for listing? It would be great if you could shed some light on this process and the associated costs.
