The same way we do now….there are security measures that can be taken to look at a bill and see that it’s legit (I mean legit as in it came from the treasury dept, it’s still fake because it’s a fiat currency). The same measures could be taken with GoldBacks, and I’m sure they could use various other types of precious metal threading so we aren’t just stuck with gold alone. I just don’t trust anything completely digital since the jews technocratic system relies on digital currency to operate properly. This entire idea to remove the penny came from Elon, you can find articles from awhile ago where he’s talking about phasing out the penny and other coins. Elon’s Granddaddy was a big player in the technocrat movement back in his day, I’m sure Elon is no different. These technocrat kikes have wanted to enslave us in an AI controlled system for decades, before computers were ever invented they were talking about a government controlled by “machines” and “experts” back in the 1930’s, removing our voice from government altogether, which I’m not completely opposed to if it’s decent White folks controlling the government, but it won’t be, it’ll be AI that was designed by jews, and the jews themselves….the AI is meant to watch the smart technology (your phone, fridge, everything that’s smart), it’ll be linked to the public cameras, the ring doorbells, your internet activity, etc, in order to formulate your social credit score. The jews will of course control the digital currency, being able to shut off your ability to buy anything they choose if you aren’t what the jew deems to be a model citizen.
