As long as the reputation of Binance (exchanges) is good and still become the top exchanges of Centralized exchanges, Binance coin could replace Ethereum.
But we can't deny the fact if Centralized exhanges always have been targeted of hacker and each year there at least 1 exchanges will be hacked, Binance ever got hacked once on 2019.
So, be aware if Binance will get hacked in the future... the coin value will got affected too.
Thanks for the concern, but I don't think Binance will allow future hacks as they have been hacked once. Only fools can be hacked twice or multiple times and still not incorporate a full security that will protect their system.
Hacks in the system of binance before tarnish their reputations, so I don't think they will let it happen for another time.
