New to Binance -- and had pennies of Ether remaining after a BTC buy without BNB. Now I know better. But, anyway, just a heads up that I used that Ether dust to buy BNB not even knowing there might be a limit. Just clicked. Well, I now have .27 USD equiv of BNB. Thought you'd want to know that the fractional is possible. I'll now use that .01999 BNB to buy more BNB, so I don't have to pay .1% to get a large amount of BNB.
