Of course it can.
I hope it goes up to 0.001 btc/doge or higher. I think it is possible because Doge could be more widely adopted and accepted mainstream than Litecoin ever could, and it is possible thanks to so much currency being in circulation.
That price will make me consider cashing out though that would make me a miljonair.
What was the reason that the litecoin had gone from around 1.70USD in at the end October 2013 to 25USD within 10 days?
