My opinion is the guy pitching is a scam artist. While the other videos you posted are correct on money theft and velocity, this guy pretending to have the secrets to save the impending new currency change (that has been coming supposedly for many years) is trying to profit off of fear.

At the end of the day, the illusion of money will lose its power when the masses can no longer eat or watch their kids grow. Currency can never be more powerful than basic human needs. The U.S. is resource rich and has enough industrious individuals despite their efforts to produce ignorant slaves that can harvest these resources if the shtf.

I think if one is convinced things are about to collapse, begin stockpiling real resources, not metals or currencies. Food, toilet paper, matches and lighters, weapons etc. These would be the currencies in demand if everything were to collapse. Their entire scheme is designed for us to give them the real resources in exchange for their paper.
