indeed cash is the best money at the moment that is used by many people, but in terms of the interbank transfer process we admit that bitcoin has its own advantages so that it is easier for us to send money to other people in an unlimited time way so that we are more we are free to transfer any amount we want, so here we can say that bitcoin can be more easily used for the purposes of sending money to other people
Even though how we much hated up Fiat for being too centralized and having that inflation problem but still it is something that most people been using.We cant just really make out digital transactions from time to time
which fiat had been used through ages and serve its purpose even though it does have its cons and criticisms but we cant really just set aside its pros and actual usage.This is why im not really that against with it
and with together on Bitcoins existence then this is something good to be an alternative and both does have its own purpose.
Both currencies fiat and crypto serves their own purpose, I agree with dunfida, both are essential in this generation, it gives us options to choose from, we can't really just forget about fiat because it has existed ever since, and it is true that both have its pros and cons, Bitcoin's volatility is considered as a pro and a con since too much volatility can be bad, and this is why fiat is needed.
