It will be not correct to compare these cryptocurrencies, although as I see, BNB is going to become one of the market leaders. probably, it is worth investing in it now as soon the price of Binance coin will go to the Moon.
but the situation is different from 2017. maybe people will think BNB will reach the highest prices like ETH in 2017. The BNB will still continue to grow, but it will wait for their blockchain development and wait for the market to improve better.
