I can't quite figure out why you have Earthcoin and Vert in the same category. EAC adds nothing new other than gimmicks aka "varies in a sine curve with amplitude of 2,000, with a period of
one year (like the Earth moving around the Sun)."
Vert basically became the #1 gpu scrypt coin in functionality. That's why people like it.
According to who? The only thing Doge brings to the table is Doge, and it has a market cap 2x higher than Namecoin.
