Can you trade Steam currency?

I'm curious, is it possible to trade Steam currency in the world of cryptocurrency and finance? I've heard about the various digital currencies and exchanges, but I'm unsure if Steam's virtual currency falls under that umbrella. Could you elaborate on whether or not it's feasible to trade Steam currency, and if so, how one might go about doing so? Additionally, are there any risks or limitations associated with trading Steam currency that I should be aware of?
