18 doge in how many hours?
doge will not reach a $0.1 and I am being optimistic about it. The most it can reach is $0.01. And it still wont be worth anything at all. You should just keep an eye on new coins released here and mine only cpu coins. doge is --scrypt coin mined using gpus. your cpu cannot compete with gpu. So you are just wasting time and electricity. mine the newly released cpu and you'll be way better and you'll make some money too. But once you have mined the coins. Wait 2-3 months until the coins blocks reward halves, coin difficulty goes high and/or it hits an exchange. So you can sell it at better prices.

That being siad. You should mine cpu only coins.
