If bitcoin will continue to be bullish, then it will always create positive market too for altcoins. And BNB will definitely be in the top list because it's already showing some significant price surging before this bitcoin bullish trend. BNB has always been active for the previous months and its value never ceases from increasing so its more likely to reach another ATH before this year ends. $500 might be reachable even by novermber and maybe after that, $600-$700 will be its next target. BNB will always have an edge in the market even if minor dumps will suddenly appear in the market for the next days.
I do believe that it will be a bullish near future, it will definitely have a great impact for all of crypto as well. Bitcoin going up means altcoins go up as well, even if not in bitcoin price, it still goes up in fiat because bitcoins price goes up. So if a coin worths 0.1 btc each, and the btc price moves from 50k to 55k, then price of that coin goes from 5k to 5.5k as well, it stays the exact same price on bitcoin, but higher price in fiat.
This is exactly what I imagine will happen, I believe that it will definitely have a great up and down which I believe will be amazing for us in the near future. I do not know how long it will take but I believe it will happen in 2021.
