Is crypto banned worldwide?

Excuse me, I'm a bit confused about the current state of cryptocurrencies. I've been hearing a lot of conflicting information lately, and I was wondering if cryptocurrencies are banned worldwide? I understand that different countries have different regulations and policies, but is there a blanket ban on cryptocurrencies globally? Or are there specific countries or regions where they are still legal and widely used? I'd appreciate it if you could clear up this confusion for me.
