@hosseinimr93, you are too good in this kind of calculation. Do you have any idea about this strange calculation system of Freebitco interest rate?
You wouldn't get accurate result for daily interest rate by dividing the yearly interest rate by 365.
Take note that not only you get interest on your initial balance, but also you get interest on interest you have earned so far.
Assuming you have 1 BTC, you will earn 0.000109589 BTC on the day 1 and you will have 1.000109589 BTC at the end of that day. On the day 2, you will earn 0.000109601 BTC and you will have 1.00021919 at the end of that day. On the day 3, you will earn 0.000109613 BTC and so on.
At the end of the day 365, you will have 1 * (1.000109589)^365 = 1.0408 BTC.
