It's already on Coinmarketcap and made it to the Top 50 for a short time.
Actually it's on Place 79 with a Marketcap of around 200,000 $, but I'm sure it will hit the Top 50 soon again.
Please add it to WorldCoinIndex. I like your site more cause it can show the prices also in EUR

Adding more coins this week.
As for preminecoins, using a marketcap rank is pretty unfair, but we will definitely add preminecoins to our site, because it is part of the crypocurrency world!
That is why need a ranking system that will be biased for pow/pos/pob/preminecoins. Also the number of traded coins are increasing as for the number of exchanges. Without new ranking we think it might confuse early adapters/ early majority and might give wrong impressions.
+1 for Primecoin, and +1 for WorldCoinIndex for staying ahead.
