"The profit is 11% annually, 1% is charged for the 24-hour support of the mining pool."

I am confused about these word while depositing my coins into pool. If i will earn 11% annually on my total deposit. And need to pay 1% daily for support of mining pool.

It means :

1% * 31 = 31% per month
12 * 31% = 372%  annually


Total annual profit - Total annual fee = Total annual Earning

11% - 372% = -361%

It means you need to pay extra amount at end of the year after depositing to mining online.
