BNB is a good coin, which has a bright future because it is owned by a binary which is actually the best exchanger at the moment, but that does not mean the BNB will beat ETH, because ETH is the best coin now after BTC
Today I divert around 2 ETH to buy a BNB (with price $33.9), I agree that the BNB is a coin that will skyrocket so it's worth buying, although I'm sure that this year the BNB price can reach at least $ 100 but this won't defeat ethereum.
