Yes, scamming is becoming prevalent now and those scammers are coming up with new ideas on daily basis in order to upgrade their processes and make it look more real.
Also, greed cause people to lose their money. They won't for anything but expect to get double interest in return of their invested money. They will end up pumping in more money they could endure to lose and lose all. The scammer takes all and run without even looking back.
I think government should also try to clap down these fraudsters. It is becoming too much.
