i am not sure about BNB, just exchange coin and it's price so high. but it will is the best choice if you trust
binance exchange. They are good team of cryptocurrency on the world.
Youre only looking on their image I think. Have you seen how binance chain working? I think it's worth every penny and even lots of super new projects are on their end. I think you can say Binance can be the next ethereum since almost all tokens ot project are shifting on binance chain. Improved and faster ecosystem but Im not saying that ethereum is weak.
It certainly capable of that however binance coin is tied to the exchange whereas Ethereum is not it is kinda different though. It is undeniably fact that most of the popular project are now using Binance's IEO which could increase the demand for BNB however everything didn't last forever just like ICO which now turn its time to IEO. BNB could lost its value anytime if the exchange did something wrong or have security breaches so people must consider that as well.
However talking about BNB I do agree that it is arguably better than Ethereum when it comes to the transaction time, will be interesting to see in depth comparison.
