I think someday BNB will beat ETH, What you Think 
if that happens it takes a very long process for Binance BNB to beat the ETH price.Current price position (7 feb 2020).
BNB position: $ 21.73
Ethereum: $ 220.77
Very far in comparison.
Ethereum is used by all ERC 20 transactions and the volume is very high compared to BNB and Eth using many available platforms.
While BNB is rarely used for transactions in general on the market, it is not the same as eth.
So, I would argue that BNB might not be able to beat the ETH price.
I agree still here is a huge difference between them but since Eth hype continuously coming down and binance is well in business. If this routine will
continue at least 1-2 year this will change the game.
maybe I don't agree that there will be a change in the next 1-2 years that binance will be able to shift ethereum. still need time for this, although in crypto can happen that are unexpected but still realistic.
