doge is a joke coin. a meme made into a coin. a troll coin to legitimite alt coins
it has the life cycle of any normal meme. first hype, then people get bored with it and jump to the next.
e.g. earthcoin has a EAC/us-dollar-only exchange planned, a android wallet and has a huge dev team behind it.
doge has what? a meme? that is of no use. dev team? you mean one guy who thinks the doge meme is funny. tomorrow he'll think something else is funny.
doge is as good as dead. and so are the inevitable cat/nyancat/[enter any meme people might have heard of]coins
this business is about serious alternatives to litecoin and bitcoin. not about having a laugh
