That's a pretty neat feature from Binance send them ETH based DUSK and they will automatically convert them to BEP-2 tokens I just tried it after reading your post and it works
Now I see that BEP-2 $0.2 and ERC20 $0.18, that is, after such an exchange, your tokens immediately added to the price of ~11% if of course immediately sell them on binance dex. Although it seems to me that the price of different tokens should still align.
