Some people don't see Bitcoin as a normal currency and think it's too risky because its value can change a lot. They also worry that it's used by criminals for illegal activities like money laundering. However, other people think Bitcoin is amazing because it's different from traditional currencies and could change how we use money. Nobody knows for sure what will happen to Bitcoin in the future, but people are still talking about it and interested in it.
To add to that, many people are still 'traditionalists' concerning money. People are more secure if they can see and touch money, to actually hold a physical manifestation of it. People want consistency and fiat represents that for them, even if the only consistent truth in the world is inconsistency (and that holds much truth when it comes to money.) That line of thinking also makes people fear the 'new,' cryptocurrency represents that fear for them. Even though Bitcoin exists for more than a decade now, many people are still finding out about it now so it seems new to them and therefore cannot still be relied upon. There are also people who knew about cryptocurrency because scammers have been exposed and went viral or were on the news, so not really a great first impression.
