As long as it has a community to back it, it will always have a market. If people give up on it, it'll die. If they keep pushing it, it's showing that a social experiment can be successful, :p.
You need more then a community to sustain a proof-of-work-based crypto currency. You need a strong network hashrate. Otherwise it doesn't matter how much community you have, the coin will get attacked, forked, and essentially destroyed. This is Doge's most likely future, and it was a destiny from the start due to a horribly considered distribution model.
Again, Doge was and is a joke.
yeah yeah, see you in a year

Probably. But I doubt it'll be in any thread about DogeCoin.
See you in another halving or two...
"The joke" is so happy and funny that millions of NASCAR fans now know about DOGEcoin (through repeated exposure) and many of them had barely ever heard of BTC, if at all. It would seem extremely unlikely that DOGE will die off any time soon.
