CASH will always be KING . And if they come out with a GOLD or SILVER backed note 📝 then it will win . Crypto can only be in addition to traditional currencies but its dependence on electronics is its Achilles heal . An EMP doesn’t require nuclear materials so that would mean more terrorist would have it . And one well placed device will send this planet back to the Stone Age . And CASH will be just fine , and so will GOLD & SILVER .
