Notes:

• Updated every 5 minutes.
• Marketcap = Price x 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) will be shown at the bottom with question marks, and will be de-listed after 7 days.  

Criteria for a coin to be added:

• Must be a cryptocurrency
• Must be traded on a public exchange that is older than 30 days and with an API available.
• Must have a public URL that displays the total supply (total mined so far).
