What can I do with BTCB?

I'm quite fascinated by the world of cryptocurrencies and I've recently come across BTCB. Could you possibly shed some light on what I can actually do with it? I've heard it's a tokenized version of Bitcoin on the Binance Smart Chain, but beyond that, I'm not quite sure how I can utilize it. Is it just for trading purposes or can it be used for payments or other financial transactions? I'm also curious about its potential for appreciation in value over time. Could you please elaborate on these points for me?
