Do you mean you have multiplied your initial investment by 50 in less than 2 months?!?!?!?!?!?!?!?!?!?!? 
Have you finished primary school yet? In no way does your calculation make sense. Take a look at this post: https://bitcointalk.org/index.php?topic=1715214.msg19956300#msg19956300.(I'm guessing the percentage made each day was over the previous day already increased, so the ammount keeps growing and growing exponentially... Am I right?)
No.First, no need to be so harsh.
I have a masters education and a reputated carreer in a completely different field, fyi.
He said he made 4,28% EACH DAY, so my calculation was:
Invest 100 --> 104.28 at the end of the day.
Has 104.28 now --> 108.74 at the end of the second day.
And so on.
If you don't want to be helpful just don't answer.
Oh, and have you noticed? I´m a newbie.
I guess I will stop asking questions in experts' threads.
