Any binance based day trader will know the frustration of Binance dust.
Binance is a large, trustworthy exchange witg a great app. Its clear layout of percentages make trading easier and more profitable.
The major drawback however is that if you trade your coins vs BTC you will quickly accumilate balances which you can't trade back to BTC. This especially affects small traders.
Buy 2 of certain coins and get charged a fee reducing your balance to below 2 coins and you will only be able to sell 1 coin as Binance only allows whole coins sold against BTC.
So what is the answer? Trade using BNB, this allows you to accumilate your dust. I recently spring cleaned my account and raised $35. I can now put that dust to work and increase it.
Binance is a great exchange and using BNB helps you to make the most of it.
