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.
Yeah, some of them I'm still familiar at like WorldCoin. But crypto's already evolved so much that some of them may have died a natural death and totally forgotten. I think its like less than 20 coins at that time and today we see hundreds if not thousands of tokens being born everyday and currently in circulation with no purpose at all but for pure pump-and-dump scheme.
