IMO, I think there's no need for Ethereum to have an additional token, they should remain as one, if the PoS is better then thats it, by the way, Im just thinking in advance because it is not clear yet if the merge will result in a creation new token but I strongly believe it's not the intention. Binance is always shown compassion to mitigate the possible scenario if it gets complicated.
Binance really cares for the investors and since they are also holding big amount of ETH probably they want to make sure that the merge will go smoothly. Though this is a usual scenario in Binance every time there’s an update, suspending the deposits and withdrawals for a while is fine, I believe ETH can pump more so have some time now to analyze either to buy or just to watch the update, it’s your call.
