Ive made some calculations, because you offer is so cool.
Well, if I deposit $100,000 for a 100-days period. If it is 1.57% a day, then we have 100 days with a total return of 1.57% x 100 = 157%. It must equal to $157,000 of profit. Why does the calculator show only $87,000 instead? Furthermore, there must be a bonus of 0.3% which is $157,000 x 0.3% = $471.
I understand that your formula may be slightly deferent, then I ask what the formula is. To be honest, I more believe to your calculator, because using my I would have enormous returns

Anyway would be so nice to have an answer from you to make it clear.
