Where could this possibly go? $0.01 USD?
Where do you see DOGE in 12 months?
Lets look at http://coinmarketcap.com/. Given that I don't think Doge's going to overtake LTC, that means a more attainable and optimistic target is Peercoin. It's been in existence since august 2012, so quite a bit more than a year. It has a market cap that's approx. 10 times that of Doge, so in a bit over a year, we may see rates of 300-500 sat. Or 0.0038 USD based on the site above. A million doge would then be worth $3800 or so. To achieve that however, we need more shops and sites actually taking dogecoin as payment. The high block halving rate may work to the currency's detriment however, since in a little over year from now (april '15), all the coins will have been mined and we'll be left with transactions. At that point, the transaction fees will probably have to be raised for it to be profitable to run a miner and sustain the network, or the coin will die from lack of hashing power and transactions taking too long.
Actually looking at the numbers, I realized that in the one month since I started, I made about 500k doge (of which 300k is stuck on Coins-E, grr), will probably hit 1 million at the halving. So 1.5 M total at the second halving, then 1.75, 1.87, 1.93, closing on 2 million by the end. That's with 2x 7950s. I predict we'll lose a lot of hashing power around the 3rd halving as the difference between 1.87 and 1.75 is a measly 7% - or 12.5% of the final coin count. At that point people will be jumping ship in droves for more profitable alt coins, if they haven't already.
