Does volume trading work?

So, I've been hearing a lot about volume trading in the world of cryptocurrency. Can you tell me, does it really work? Is it a strategy that's worth investing time and effort into learning? And if so, how does it work? Is it about analyzing trading volume to predict price movements? Or is there more to it than that? I'm eager to understand the basics and whether it's a viable option for me to consider in my own trading journey.
