In some sense, Bitcoin is better than Fiat because you're free to do whatever you want with your money without fear of censorship from a third party. No one can freeze your Bitcoin or deny you access to it, thanks to the decentralization of the core Blockchain protocol. I'd bet if Bitcoin would've been a stable cryptocurrency, it would've been widely accepted by mainstream merchants, businesses, and companies alike. At least, the number of people adopting Bitcoin is growing. Whichever form of money is best for daily payments, that's up to you to decide. It seems to me that both Bitcoin and Fiat will co-exist alongside each other for years to come. Just my thoughts
even if it is forced, it still needs to be improved, which may not be as fast as predicted.
actually bitcoin and fiat let only stick to their respective uses because they are still needed by different people. let bitcoin run and support every where fiat can't do or vice versa where bitcoin can't work there fiat. complement each other for more advanced improvements.
