Coinmarketcap
Coinmarketcap is a website for tracking capitalization of various cryptocurrencies.
Summary
The page provides various data about several listed coins, such as their price, available supply, trade volume over last 24 hours or market capitalization.
The statistics are updated every 5 minutes. Market capitalization is calculated by multiplying price by total supply. Prices are calculated by averaging the prices at the major exchanges weighted by volume.
Coins with stale datapoints (more than 6 hours old) are shown at the bottom of the list with question marks, and are de-listed after 7 days.

For a coin to be added it must meet following criteria:
- It must be a cryptocurrency
- It must be traded on a public exchange that is older than 30 days and with an API available.
- It must have a public URL that displays the total supply (total coins mined so far).
