Does it require margin for that?
Or can you only sell covered BTC puts?
Hopefully someone who trades these options on Binance can chime in here.
Or you can watch this video that I found on Youtube:

You can find tons of good videos on Youtube to know how margin trading works. But I can suggest using regular trading as that is the simple mode for new people to crypto trading.
