Where did you went to school??? People are currently receiving about 80% on a 4 month term. If we repeat this over a year that makes 3 terms and about 240%, what is reasonable in the current bitcoin environment. Was the other day in a skype group and people told me they make much more with other Bitcoin related ventures.
You don't have to wait before you reinvest the profits. If you did this every time they pay and assume there are about 240 of their trading days in a year and they pay just 1% every time, you get a profit of 1.01^240 ~ 10.9 or about 990% profit in a year. As for your skype claim, most likely either you or they are lying.
