Hint to anyone who wants to invest - payments come exactly every 24 hours. So it's better to make the initial deposit in the morning than at night, so you might end up squeezing out one more payment if they cut and run. It's also more convenient.
The interest rates are too high and cannot be sustained even for short term.
According to my understanding, the interest rate work out so you get 144% of your initial investment back after 12 days. Interest is not compounded and they take your initial investment. This means that the rate is much lower than what they make it look, so it is more likely to last a while (at least the way I see it).
