Ask BingX exchange. If they believe Bitcoin isn't fungible, use a different exchange.
I asked the BingX exchange. I'm waiting to hear back from them. If they reply to me and I make the transaction without any problems, I will immediately report it here on the forum. But I would also like to see a response from an eXch rep or support.

You are right, but unfortunately we now have to live with this “taint” because we couldn't beat it.
