i dont think cryptocurrencies are better because they can not work offline and transactions are not very quick like they are in conventional money. moreover,transactions charge high feesBTC which makes their use impossible for small transactions.
Why do people hate the high fees while the price of bitcoin is so high and the people using it multiplying, the fees will obviously be having an increase too.
But the thing is, these conventional money or the fiats are far more better than digital currencies. It needs a lot of years before it needs to be compared to conventional money.
