I have many trader friends and I am a trader myself, there are few people who are a cryptocurrency trader but are not familiar with binance exchange. For those who do a large number of trades per day, the cost of commissions increases. If we are a user of Binance exchange and want to pay less fees, I think it is better to buy some BNB, ie Binance Coin currency, because this exchange has set a good discount for fees paid with bnb.
In terms of investment, binance coin has been very profitable and can grow much more in the future.
