When you talk about trusting a coin, you have to look at different achievements of the project working with the token or coin, the background and level attained. To me, Ethereum is a base token and can't be compared to BNB, unless there's better and strong competition from BNB. I go with Ethereum.
Yes,your post is so positive. I am agree with you.Both of the coin are popular and trusted. But the eth is called the king of altcoins. So,i go with eth.
