CoinMarketCap

CoinMarketCap is the most widely cited reference for cryptocurrency prices, market capitalization and volume rankings.

Its rankings shape attention: appearing high on the list drives traffic and perceived legitimacy, which is why listing and ranking methodology matters more than it might appear.

Reported volume in particular has historically been inflated by exchanges, and the site has adjusted its methodology over time to account for that — worth remembering when comparing assets by volume alone.
