I think there might be some cherry picking effect here. I.e. there are probably around a couple hundred crapcoins around -- are you comparing us to an average crapcoin, or only to the best crapcoins?
Also keep in mind some of those market caps might be paper numbers only. Crapcoins can have illiquid markets (so the market cap doesn't accurately reflect real demand), low effective float (due to premining or other manipulation resulting in much of a coin in the hands of a few), or market manipulation (your data may merely be illustrating the pump stage of a pump-and-dump).
