Binance is doing a promotion as a thank you for sticking with them. They are giving away 50,000 BNB to users who trade more than 1 BTC worth of crypto and offering a free level up to VIP users.
Binance Coin (BNB) is Binance’s official crypto token. One big perk of the coin is that holding it on Binance reduces your trading fees on Binance.
Binance is a cryptocurrency exchange and wallet. They are one of the top exchanges for trading altcoins, have low fees, and have become the number one exchange for Bitcoin by volume as of 2018.
