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.
Thank you for clearing the doubts. I was using the general calculation formula without considering the compounding system.
My initial question was how long I should wait for support from freebitco before I open a separate Scam accusation here?
You don't need to create any accusation. Check the above post of hosseinimr93 to know how the APY is actually calculated. Currently your daily interest rate is 0.01178082 including the boosted amount. If you hold 1 BTC on your account, then you will have 1 × (1.0001178082)
365 = 1.0439 BTC after 1 year. The interest amount is 0.0439 BTC, which is 0.0439 × 100 = 4.39% (your APY with the boosted percentage).
