Both ADA and BNB are good altcoins and they deserve to hold. But ADA seems to have more good news now, BNB has some bad news after CZ has a problem with SEC. So, I think it is better to prioritize to buy ADA now. But it is not a bad idea to keep buying BNB. BNB is always good altcoin, it still becomes a top coin whatever the problem faced by Binance exchanges.
I think both ADA and BNB are still cheap now. ![Wink ;)](https://www.altcoinstalks.com/Smileys/default/wink.gif)
I don't hold these two altcoins, but I have seen a little about the development of the BNB coin, which is currently still in position 4 on Coinmarketcap.
CZ's lawsuit against the SEC did have some impact at the start of this problem, because he resigned and underwent the legal process as required.
But now BNB is becoming more popular with whales holding BNB in preparation for the launchpad on Binance, currently there are several lists of project names that will be listed on Binance, this is good news and the price of BNB has also risen to $300.
As for ADA, I don't know exactly right now their ecosystem is still not popular enough even though there are several projects under the ADA coin contract.
