TD Ameritrade Learning Center. “Bar Chart.” Join our mailing list No, we do not list all cryptocurrencies at CoinMarketCap. As a company and team, we are very aware that not all coins and projects have good intentions. While we cannot guarantee to exclude them all, we have a vetting process that each coin goes through before it is listed on the site. If we suspect that a coin or project is a scam, it does not get listed.
