To be honest. Both. Because both coins are really good coins. I have no complaints with that. But in making money wise. I'll go for BNB. Because i feel like BNB has the right amount of volatility to profit more than ETH. But still, ETH is still a great coin to invest or trade on. But I feel like BNB is better than ETH when it comes in the market.
Each one has a different a characteristic when it comes to trust I have strong faith in ETH and BNB. It completely depends upon the people who choose their target to make a profit because it is not our decision to purchase BNB or ETH. It is their decision which one is best for long term holdings.
