I have never heard of the penny being related to the US currency before.
Just looked it up on Wikipedia and it says...
"The one-cent coin is often called a penny, but the U.S. Mint's official name for this coin is cent."
It's amazing the stuff you can learn on here!

no i am speaking of an american penny. I dont know how to convert so i could not ask this question in any other currency. But if you know what would equal once cent. then it would work the same way.

First, I'd like to share with you that I'm an individual who loves solving puzzles and brain twisters, including math puzzles. And I do attribute this to the fact that I am mesmerized with numbers because I'm an Accounting course graduate. And I told myself that I'd like to try this puzzle you mentioned, which I did.
But I want to show you how I come up with the answer before revealing my own answer. Here goes.
I did this in an excel worksheet; with determining the number of days in a year first, which is 365. Everybody knows this, of course. Then, on day one, I wrote 0.01 equivalent to a penny, which honestly I'm not sure if I'm correct or for this particular reason, my officemate; because he's the one who told me that a penny is equal to 1 cent. After this, I multiplied 0.01 with 2 on day 2 because it doubles. So I copied the formula until the 365th day.
Then, what I had got me surprised and giggling. It exceeded a million; in fact, it even exceeded thrillions or octillions. I definitely thought I was crazy. Did I do it correctly or did I misinterpret it? But something suddenly striked me. Are you, in any way, associating this with earnings in the internet?
Anyway, I do hope to know the answer from you soon. Regards.

it was just a hypothetical question although it would be nice if you could do that on these sites. Just keep all your money in a pay pal account if you have to cash out. Who knows? I dont know if i could do it i think i would end up cashing out before i got there. Good Job on figuring that out i started doing that but soon gave up. Math is not really my forte. But it really makes you think dont it?

i was actually trying to do this math in my head and i got confused after the 8 cents. i dont think it would add up to a million dollars but you would probably get a pretty decent amount of money in a year. after reading this i am really interested and thinking about trying to do a test and see how much you do "make" in a year, but probably after a while it would be hard to double the previous day.
