I think if Bitcoin becomes a centralized fiat and if Bitcoin is managed in some way, it will not be good at all. Rather, the position Bitcoin is in now and since it has been managed in a decentralized manner for many decades, it can be expected that Bitcoin will be better in the future. Moreover, Bitcoin is currently a popular digital currency in the world, many people have faith and confidence in it, every person invests in it. Moreover, Bitcoin has always given people financial freedom, so if Bitcoin remains decentralized in the future, it will only gain more popularity and its price will reach higher positions.
