It depends on whether you count the first day in the 30 days.
If you have one cent and on the "first day" you have 2 cents, and as day 1 is equal to 21 then your value on day 30 is equal to 230 cents ($10,737,418.24)
This exponential function can be represented by the equation: f(x) = 0.01(2x) where x = the day number. If you plug in 30 for x, you get f(x) = 0.01×230 = 10,737,418.24
Here's a slower method of finding the answer:

0.01×290 equals $1,237,940,039,285,380,274,899,124,224
SavingsIf you start with $0.00 and save a penny daily, you will have saved $3.65 in one year (or $3.66 in a leap year).
If you start with one penny on day 1, assuming it's not a leap year, you would end the year with $3.65
If you start with a quarter (0.25) and double your money every day for 30 days, you would have (0.25 \times 2^{30}) by the end of the period. This calculation results in approximately $268,435,456. So, after 30 days of doubling your quarter, you would have over 268 million dollars.
that's two raised to 60... use a scientific calculator...

Oh, dude, let me break out my calculator for this mind-blowing math problem. So, if you start with one penny and double it every day for 365 days, you'd end up with... drum roll, please... $1.84 quadrillion! Like, who needs a lottery when you've got compound interest, am I right?

There doesn't appear to be a common definition of penny stock fortunes. Penny stock means different things to different people. However, the typical penny stock is a small business that has speculative shares, so buying is a risk because of their lack of liquidity.
A dime a dozen, A penny saved is a penny earned, A piece of cake, A toss-up, A fool and his money are soon parted, All bark and no bite, Actions speak louder than words.
start an event and tell them you can double their money in 2 trades and when they give you the money in the first trade kick them out!
Start paying people/companies you owe money and you won't have to worry about things like this. And yes, they can if they know you have an account. In California we no longer need to know the account number, just where you bank and the sheriff can take the writ of execution from the creditor that you owe money and take every penny they deserve.
