Crypto Rush charges a fee to be listed and doesn't seem to have a very large trade volume.
Funny - coinedup doesnt have a super high trade volume, is laggy as shit, and Kittehcoin (MEOW) crashed their servers when it was released on there. Popularity will always be a winner.
Im surprised the trollcoin network hasnt gotten as big as the DNotes has.. yet
Also, Im surprised that Dougcoin is listed so high when Oxcoin seems more promising im my eyes.
