I have a question dude, why are you asking this question anyway? And about mixers on Binance, as far as I know, it doesn't have any mixers
just like what you are asking for here. I remember before there is a bitmixers and I'm not sure if that is the thing you are talking about here in the topic.
He's not asking about binance mixers but about binance smart chain mixers. Those mixers that has a support for BSC network. You've mentioned bitmixer, they've been closed long time ago.
And also, there's also the answer for his question that tornado cash supports BSC. Still, his best option is to use tornado cash.
