What's your ultimate choice? Or both?
ETH is good and BNB is better but there are differences between the two, such as Fees. ETH fees are increasing rapidly while BNB fees are getting cheaper. I am in the middle of these two blockchain platforms because I love ETH and BNB. both of these coins are good for long-term investments.
fee is the main reason why BNB was getting famous for a moment there, back then so many are looking for alternatives for ETH because of the fee and BNB becomes good alternative, that makes the BNB right now with its good valuation, though currently BNB is infested with so many shit coins, even I think matic is better compared with BNB, if I were given a chance to choose I'd choose ETH despite the fee.
