yes, why not. because crypto mass use in daily life will be very helpful, but you must know that fiat money will not be replaced. if crypto has been used every day in life, it does not mean fiat money like the dollar will end and is useless, but crypto will coexist with fiat money and are interconnected between the two.
right, crypto currencies and paper currencies will be used side by side because they are functionally different, both will complement each other, dollars will still be international money and cryptocurrency will be digital money to cover the weakness of paper money.
