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.
I think you are mistaken, yes. I'm pretty sure the formula is a bit more complicated. At least these returns are better than in any bank, even if we are talking about new crypto banks. Getting goods with money earned by mining without changing them is a great thing.
