It seems to me that the OP had a strong suspicion about this investment, and therefore asked a question before deciding to invest. After getting an answer to his question he simply disappeared, as do most beginners who register on the forum just to ask a question and are not more seriously interested in Bitcoin.
In my opinion, the biggest problem is that someone thinks that such things have anything to do with something legal and profitable, which leads us to conclude that the Internet is a very dangerous place for those who are not aware of all the dangers that threaten them from all sides.
Facts, Many of my newbie friends know the risk on investing on rhis kind of scam scheme but they still choose to try it because they are tempted on the huge return for a short period of time. There still some ponzi scheme that paying early investors then just scam later which leads to some user keep on risking hoping that they will be paid as an early investor.
