This is just crazy and I know people will buy this nonsense and invest their money.
One time we had a scam group who claimed to be poloniex exchange and they offered people huge ROI in 3 days, these guys were able to generate more than 5 million in their first few days at office, at the end of the day they scammed everyone and left.
Nobody saw them when they left, all we know is that they left and we never say the again.
The fact that many look at the supposed profits without considering the risks or knowing what it involves is the reason such scams will continue.
It's quite unfortunate.
