Monero was popular since it ever reach top 15 coins in CMC, but due to government want to kill privacy and control everything, they force the centralized exchange to delist privacy coins. This is why the popularity of privacy coins keep declining and centralized coins regain it hype.
Obviously we need a privacy coin to protect our privacy, do you think you don't need any privacy? you can share your real name, your face, your house, your total wealth here.
I do not think that I need it, but I also do not want to share my face, ID and all that here at the same time, there is a huge difference. Think of it this way, if you know my transaction and you are aware of it, then you only know my address and my transaction that's it, and I do not feel the need to hide that, but if I use bitcoin, that doesn't mean you know my name, my face, my address and my id. Those are different things and not the same thing.
Monero hides your transaction, but bitcoin hides who you are if you want to, you could also do KYC and all that will be open to public if it's hacked, which happened a few times but that doesn't mean that you should do it neither, there is a small gap between monero and bitcoin privacy.
