Because the title of the site then and so my old bookmark reads "Crypto-Currency Market Capitalizations | Bitcoin Litecoin Peercoin Namecoin Novacoin Primecoin Feathercoin WorldCoin CryptogenicBullion Devcoin and more..." when I set the bookmark in around 2013. Only two, Bitcoin and Litecoin are still widely talked about, the rest has more or less gone into oblivion.

I just thought I'll mention it.
