I saw a cryptocurrency influencer on YouTube say that he is optimistic about BNB. The reason is that everyone uses Binance for trading, and there are always transaction fees. If everyone uses it, they will certainly make a lot of money. Moreover, holding BNB not only allows for occasional mining and receiving free airdrops, but also offers discounts on transaction fees. For those who trade frequently, the accumulated savings from transaction fee discounts can amount to a considerable sum over time. Based on the consideration of trading costs, I suggest everyone consider buying some BNB to hold in their inventory. Although there are no significant interest returns, the related benefits provided by Binance, along with its relative stability and potential for gradual appreciation, make BNB still worth buying.
