A quick reality check on what CoinMarketCap actually does—and doesn't. Many people mistakenly think CMC is a trading platform where you can buy or sell crypto. That's not the case. The site serves as a data aggregator and tracking resource, not an exchange. You can't execute any trades directly through it, nor can you withdraw tokens from the platform. The Portfolio feature that CMC offers? It's purely a tracking mechanism for monitoring your holdings—definitely not a crypto wallet. Think of it as a spreadsheet that syncs with market data, nothing more. Understanding these distinctions helps you use the right tools for the right job.
