BNB's performance is actually highly affected by Binance's (exchange) performance. With every good update (such as the recent Binance's acquisition of Trust Wallet) provided by Binance, BNB shows some positivity in value. Moreover, Binance just keeps adding more & more new advantages (for traders) for holding/buying BNB. In simple words, if you're a believer of Binance (and especially the upcoming Binance DEX), you should get some BNB.
The future's Binance decentralized exchange (Binance DEX) will be highly dependent upon Binance Chain (blockchain of BNB coin), and even yesterday, when CZ in an AMA session at Twitter announced that the DEX is now near to completion (and the testnet of BNB coin will be made public soon), the BNB token pumped almost 5% immediately.
I like it. It's almost like an STO which follows the performance of the underlying business, and offers some benefits too. I do however have to point out that it still continues to follow Bitcoin closely.
If it wasn't for BTT and TRX pumping hard and using Binance as platform, the price would be a notch or two lower right now. It would be a good start for once to see it go its own path, but I doubt it at this point.
It could be that the decentralized exchange will be that push, but there is a lot needed to get people to use it, even for an entity like Binance. I only see it take off if they reward users....
