On my opinion, bitcoin is the fiat of the cryptocurrency because all altcoins depends it value to the Bitcoin,
It just like in real fiat, USD is an international currency on my opinion as of the moment, but even that is the international currency we also have different currency in different country, just like altcoins.
If Fiat will be gone, bitcoin sill be the fiat of the future.
TRUE! BITCOIN is everything in this crypto community, world without FIAT will be hard to people as they are not relying on the internet.
some of the countries have poor internet connections. bitcoin is very fragile in the market and as a new holder of bitcoin will be a big risk. we should consider that today with bitcoin + FIAT is the most beautiful thing we can have in life.
