Dogecoin is pretty much gone...Hardly any buy orders on Mintpal, Lost more than 80% of it's ATH price. Only 50 btc worth of trading going on @Mint, and that amount is decreasing everyday....
This coin won't see another 4 months before dying off completely.
What makes you think that it's the coin dying. The price might be on a downtrend but the fact that the trading in mintpal has decreased doesn't mean much. I don't see what your poit is. 50BTC volume on mintpal? Well DUH... what would you expect? If the same ammount of coins keeps being exchanged with a lover price it's logical that the btc volume will be lower. Cryptsy, BTC38 and BTC100 still have a stable volume.
