Anyone that trades on Binance can use BNB (Binance Coin) to pay their trade commissions fees and receive 50% off the fee. It doesn't make sense not to own a little BNB when you are doing a lot of trading on Binance to save on the fee. Make sure you enable to use BNB to pay the fees in your profile. As you can see below, Binance has the 2nd highest volume of trading for a crypto exchange and it's trading tools make it one of the best for day trading quality coins. Whenever the market makes big gains or tanks BNB increases in value because increased trading = increased number of people buying BNB to save on trading fees. I've noticed on those bloody red days where everything plummets besides Tether being green Binance yields 5% gain or even higher. Take a look for yourself the next time there are big moves in the market.
Today Bitcoin is down 5% meaning lots of trading on altcoins and Binance is showing gains as high as 6-10% due to the increased trading. It seems to be a consistent safe bet in these situations. Good Luck Trading!
