Scammer never disappointed about what have they did, always doing the same thing to get investor money without care how much they have earn before, always looking new way to earn much money with wrong ways.
Overall it is not fair to steal the money from someone, but scammer does it without problems. The scammer is always looking for a new way for two-timing investors, to put it another way, they let investors very badly. It might well sound unbelievable, however, there are still some people, who trust them. These people like to repeat the same mistake.
