People buy it because it has a real userbase unlike most other coins.
What features does your fiatmoney have? You think some more buttons, new graphics, some bling, an in-wallet-chat and some broken new features is what gives a coin value?
Sorry to pop your bubble but security, userbase and scarcity is what gives a coin value - not features.
Doge will be around for some more time, don't you worry.
People who see what the real traffic from real users is on those chains are buying DOGE with a big smile and a "thank you" from you retards.
Doge will be valued higher than ETH in the future once the dust settles.
