bitcoin has many advantages
fiat has many advantages
That's why I don't see any reason to make comparisons.
for example:
fiat is recognized by governments which allows it to be used in countries, everything you buy uses fiat, people receive a salary using fiat, but there are maximum values for walking on the street with fiat, something that does not happen with bitcoin where the person can be their own bank
I dont consider this advantages for the fiat money. Fiat money is controlled by the governments and they can print as money currecny as they want. They do provide the security and take responisbily of the currecny, but they never promise you for inflation free economy. Bitcoin is volatile and have some little issues but these can be easily resolved once it is adopted by everyone. Government dont reconzinge bitcoins but who cares. They always want to make us slaves by controlling us and not providing the public with finicial freedom.
