I want to know the difference between fiat and bitcoin.
The difference between fiat and bitcoin is that fiat money is a physical money like for example:
* Canadian dollar
* US dollar
* PHP
* Thailand bat
And so on, while bitcoin is a virtual or digital money currency that was created in 2009 by Satoshi Nakamoto.
and without fiat existence can bitcoin have a name?,
Bitcoin and fiat are completely different, it is true that they work like brothers. However even without the fiat existence, the bitcoin can still exist but right now at the moment fiat money is highly needed for own needs like goods and other services that is why i understood why others tends to think that bitcoin cannot exist without fiat but then again in my own perspective i still do believe that bitcoin could still exist. It is unique in its own way.
