Why is immutable better?

I'm curious, why is immutability considered superior in the realm of cryptocurrency and finance? Could you elaborate on the benefits it offers? It seems like a concept that's often touted, but I'm not entirely sure what makes it so advantageous. Is it related to security? Or does it have something to do with the integrity of transactions? I'd really appreciate if you could break it down for me in a way that's easy to understand. After all, isn't it possible to achieve similar objectives with mutable systems as well? What makes immutability stand out?
