stablecoins will be a good step in the right direction to get rid of cash. Then all the drugs cartels and criminals with loads of cash hidden in warehouses will have to exchange their cash for stablecoins but they will have to explain how they got so much money, lots of warehouses full of cash will become worthless.
Once we are on a full stablecoin standard, Bitcoin will continue to eat up their stablecoins and Bitcoin will be the only currency left.
