How did you get it is a scheme? As I was looking through the site and it doesn't seem to be a ponzi. I want to know how did you mentioned that as I am trying to learn such things to be more safe from any schemes
Number one method of recognising scams: calculate the yearly profit percentage from the daily figures they use to confuse. If it sounds too good to be true, then it's too good to be true.
In this case, they advertise 0.1% to 10% daily profits (this should already be a massive warning sign: if you can make an insane 10% daily profit, then you are taking extreme risks and must have days of bad losses as well. These guys claim to only have profitable days). But let's estimate based on their reported profits for the month: they claim to have made about 1.8% profit per day on average. Maybe that sounds like it's possible, but calculate a yearly profit from that first: 100* (1.018^365 - 1) = 67287%
67287% -> SCAM
