What is ChangeNOW in crypto?

So, could you please explain what ChangeNOW is in the world of cryptocurrency? I've heard of it being used for exchanges, but I'm not entirely sure how it works or what sets it apart from other platforms. Is it a wallet, an exchange, or something else entirely? And what are the main benefits or features that users can expect from ChangeNOW? I'm curious to learn more about this platform and how it fits into the broader cryptocurrency ecosystem.
