When spending money abroad, which one is more advantageous, cash check card or credit card?

pu1. It depends on the exchange rate
If the exchange rate goes up, cash is the best
Because credit cards are not based on the exchange rate at that time, but on a certain point in time, it's more expensive if the exchange rate is rising
It's the same as a credit card because it doesn't take as long as we do

OK

pu2. Cash is advantageous
Credit cards and check cards have separate fees
In other countries, people pay about 1% of credit card fees
