If I may ask, what do you mean by BNB is shit centralized coin? I take this to be a typo error as am totally against and won't agree to such assertions. BNB is one coin that has shown good improvements in the recent time and still coming up with more.
When someone says centralized the first thing that came to thier mind is negative because this limits the purpose of cryptos which supposed to be decentralize but bnb is different to those other centralized coins because bnb is somehow useful along with its exchange binance but i dont think that bnb can rule the altcoin section because for me eth is still the one and no one can revert it .
I think BNB Coin is not centralized. Maybe at this time ethereum is better than BNB Coin but it seems that many altcoins are switching to using BNB Chain. The development of altcoin is very fast and maybe some time will come there will be a new coin that might be able to shift the dominance of ethereum or other altcoin
