What can I do with stETH?

I'm curious about the potential uses of stETH. Could you explain what sorts of things I could do with it? I've heard that it's gaining popularity in the cryptocurrency world, but I'm not quite sure how to utilize it effectively. Would it be suitable for trading, staking, or are there other applications that I should be aware of? I'm interested in learning more about its capabilities and how it could potentially enhance my crypto portfolio. Could you please elaborate on the various ways in which I could leverage stETH to my advantage?
