You can't beat coinmarketcap, cause there's nothing to beat here. Coinmarketcap and all other similar sites should use just for basic info about some project, and even that basic info should be rechecked at some point. Bottom line is don't trust informational sites with everything you have, they can fake volumes, ranks, they can do what ever they want, and in the past they done it, many people believe in those informations with their money and they lost that money in the end.
maybe what he meant for beating is the popularity since CoinMarketCapitalization is the most popular site when cryptonians are looking for info regarding deatils.
and i believe that there must be some site to do such those with credibility and reliability as CMC has already lose more believer since they start to fake the volumes of some shitcoins in their lists.
this is something that must be take seriously so having another one will be much better for the whole community of crypto.
