Can I buy on CoinMarketCap?

Could you please elaborate on whether it's possible to purchase cryptocurrencies directly through CoinMarketCap? I've been hearing a lot about this platform and its comprehensive listings of various coins, but I'm not entirely sure if it offers buying options as well. If it does, what kind of payment methods are accepted? Are there any fees involved? And most importantly, how secure is the process? Your insights would be greatly appreciated as I'm considering adding some coins to my portfolio.
