Well, it's not the wise decision just because it's one of the to altcoins. DOGE and XRP are too, but they're not worth buying. Also, I don't think accumulating a coin that is heavily connected to the exchange is a good idea. FTX story should've reached us something.
BNB is surely one of the altcoins but it is a top altcoin. For me, BNB isn't comparable with Doge, BNB has a strong fundamental to invest in. Although it has a problem with SEC, it doesn't take away of the fact that BNB is a native coin of the best exchange in the world. And it has a crucial role for Binance exchange. With the important role of BNB, no doubt that it deserves to be the good option for investment. Anyway, if you compare it with XRP, you must get a positive thing. You can see XRP increasing its price constantly after Ripple won against SEC. This also probably happens to BNB, it can raise constantly again when Binance can solve their problem with SEC.
FTX story is unlikely to happen with Binance. I'm sure Binance isn't the same situation as FTX previously. What SEC accused to Binance, is something difficult to prove. IMO, SEC won't have a chance to convince the judge at the court.
