Hello, CoinMarketCap is not an exchange. We do not buy or sell cryptocurrencies. CoinMarketCap is a website that provides cryptocurrency market cap rankings, charts, and more. Our website tracks capitalization of various cryptocurrencies by listing prices, available supply (amount of coins that is currently in circulation), trade volume over last 24 hours, or market capitalizations. Thank you.
