because with inflation, it will cause market prices to change very quickly, or even inflation will cause the price of tokens to be worthless in some types of FIAT currencies, therefore inflation is a matter that is very burdensome for prices in the market, and the benefits we can get .
But in crypto currency there is no inflation,the prices were determined by supply and demand since once the number of tokens were created it will have maximum limit so no cause for inflation here,if your fiat undergoes inflation then your crypto currencies will get more value than current so you no need to worry about fiat inflation while holding cryptos.
