I really love BitcoinWisdom. Not just for the fact they offer charts, but also because they try to add coins which aren’t either Bitcoin, or Litecoin.
These “other” coins are all coins with unlimited potential, such as DogeCoin, PeerCoin,NameCoin, and now also WorldCoin!
The information for the WorldCoin chart is taken from the Cryptsy exchange, where WorldCoin is traded against both Bitcoin and Litecoin. Only the WorldCoin/Bitcoin trading pair information is available at this point.
