If we talk about the compound interest ( % ) then your profit will be equal.
1000*10%=1100$
1100*10%=$1210
$ 1331.
1464$
1610$
....
3138$
3452$
That is, we can say that the profit for the year with a complex percentage (Monthly reinvestment) Is 340% per year.
That's a pretty good profit. Question where is the money? If the company wants to collect 2 million coins, it means that for the year they have to attract more than 6.8 million dollars from advertisers. Of course my calculations are approximate, but the point is that +4 million exactly need to be found for payments on their obligations.
