I would like to see a GOLD or SILVER backed cash 💵 , because its liquidity is KING . You just can’t achieve the money velocity with a restrictive measure like cryptos . If there were an electronic Armageddon then what would you do❓CASH doesn’t have a problem once its in your possession . An electronic toy can be lost , stolen , or hacked . Can’t hack CASH . Still like blockchain and some forms of crypto out these , but only as back up to cash . Otherwise I guess we’ll all have to walk around like in medieval times with a little leather pouch full of GOLD & SILVER bits . LOL 😆
