It's actually 100 billion.
I have a GeForce GTX 680 that is getting ~200 KHs, while my pool generates ~200 MHs, and the net rate is ~600 MHs.
My card was getting ~120 MHs with Bitcoin. I just started last night and have 94k Dogecoins.
Sure, it's worthless... but it's hilarious and quite fun to be part of such a new community.
More like about 100k per day with the existing difficulty.
Hah! If its at this rate then 100k = 1 cent or something.
