When you get a small remaining from trades which you can't sell, use convert to BNB feature to get rid of it.  It converts small balances to BNB, and then you can sell BNB or use it to pay fees.

Check below where you can find this feature. Once you found it, select dust you want to convert then press "Convert." 

Please note you can do this one time a day.

Switch to the "Convert" tab.

On 3Commas Binance Trader

Open "My Exchanges."

Click "Show my account" under Binance Trader.
