Within 4 years it is very possible that the price of a bnb will reach $3k. Currently the function of BNB is almost the same as ETH. Moreover crypto will be more and more popular every year, I am pretty sure the future of crypto is very bright in the future.
If binance can cover a 3k USD value within 4 years time , then ethereum might hit 10,000$ and up then so still Ethereum will be the second largest currency in crypto.
Binance is good no doubt about that , and also this has real back up having an exchange but ETH had stablished the position years before the Binance was born and that made eth the second respected and trusted cryptocurrency of our time now.
