BNB is connnected to a single company, and even more to whatever CZ does. The fact the he constantly denies his whereabouts and the location of the Binance HQ could cause some troubles in the future, taking the value of the BNB coin with him. Ethereum has the chance to become the industry leader for the decades to come, doesn´t even matter what Vitalik does or says
but the main power of BNB is CZ itself, they got big name at Cryptocurrency exchange and when BNB created at ethereum blockchain people are very interesting in this project because fully supported from Binance and of course other exchange take chance at the moment
