The only hard currencies are gold and silver (maybe copper and lead). Crypto currencies would replace fiat paper currencies. That's not really their goal either, they want the ability to inflate and crypto currencies cannot be inflated.
So what they really want is digital payments in fiat. When they say "convert hard to digital" they want to replace cash with credit. That way they can track everything and control anyone as the need arises.
Only certain cryptos cannot be “inflated” (like BTC) many others can be “Psudo-inflated” thru chicanery (like “XRP”). Also I doubt any government “digital currency” would allow the end user to have their “private key” if it is an encrypted digital currency.
BTC at all time highs recently with government $$ printing and large purchases of BTC by institutions.
Very much agree
