Many people have misconceptions about the functions of CoinMarketCap. Let's clarify. First, it is important to understand that CoinMarketCap is not an exchange at all; do not think about buying, selling, or trading cryptocurrencies directly on it — it is simply an information platform. Second, you cannot withdraw tokens through CMC because it does not have asset settlement capabilities. The third point is crucial: the Portfolio feature on CMC is just a tracking tool; do not use it as a wallet, as it cannot store your crypto assets. In simple terms, CMC is a place for checking data, tracking market prices, and managing your investment portfolio, and it does not involve any real trading or asset custody.
