Retirees unfortunately are among the most targeted for scams. Be sure to consult an advisor prior to making any investment or laying out a large amount of cash on anything. Scammers will prey upon your desire to grow your savings.
Even if you are not retired or about to retire, always keep a certain level of skepticism when it comes to the investments being presented to you. Do your research first: ask about it and search for it online. You might just find out that this whole system is just an elaborate way for people to get money out of you.
