Ethereum is always my first choice in altcoins and these days this is a decent altcoin for making a good amount of profit its rank proves that crypto community mostly prefer eth and the other side bnb looks a risky option to me because its value is depend on hype.
That was a good choice for you. Ethereum still gaining more supporters despite of all the negative that the teams have been facing on the other side but they could still sustain its momentum and trying to get back in the race. It is no doubt about its profitability but it is much better to look another one just to accompany with and I suggest to take a look into the top 5 altcoins in the market.
