What should I do?

I had invested a small amount using the Binance app of around 234 usd in bitcoin in the year 2021, i was a kid then borrowed money from my dad. And during the trading, I didn’t know what I was doing and thought I got scammed and let it go, after like 9 months my cousin got me my money back in the app wallet sitting at around 331 usd in BNB.
And I dumped all of that in bitcoin immediately.
A year ago(2025) it had gone really up. But I chose to hold worried it might go even higher, also didn’t know how to withdraw it.
Today it’s gone down quite a lot but I’m still on a decently good profit considering my investment.
I know I’m a small fish, but I really would love to learn more on how to use Binance and make the most of my investment.
I’m not really sure about Binance earn, could anyone tell me how to use that? If I’m planning on keeping it locked since I won’t be really selling whatever I have for quite a long time.
