How gullible can you get? He's "disguising his voice to protect his identity" . . . but he claims to be the CEO of one of two companies that have a federal contract to print money. Duuuh! Money is printed only on giant intaglio presses that produce raised patterns on special paper that nobody but the government owns. Not on ink-jet printers.

Counterfeiting is a federal offense. It's just a video to get complete dumbasses to click on the link and be marketed to. I have no idea what he is selling, cause I ain't clicking the link.
