I chose both, although they are almost similar but also very different, the most basic thing is the transaction fee, BNB is cheaper than ETH. Therefore, there are far more BNB users, but on the other hand, ETH users contain whales. The ecosystem is also the same, nothing is different.
It's hard to choose between BNB or ETH, because both are top potential altcoins. So investing in both will be very profitable, that's why I always
include BNB and ETH in my portfolio. As you said both are almost the same, so there are advantages and disadvantages of each, investing in both is
the best choice. So if indeed BNB and ETH can both give us an advantage, why should we choose one, I suggest investing in both. Moreover,
the founders of BNB and ETH are people who really understand the crypto world very well and are also very experienced, so they understand how
to develop projects to be better and survive in the crypto world. Because there are so many new projects that end up being scams, that's because
most other projects don't have a competent and experienced founder and team of developers.
