honestly I think BNB is better compared to other similar coins, it has the big community, there are still quite many nft games that still quite famous running in bsc meaning bnb still have a lot demands, I think it will never crash, binance is also doing quite good enough to keep their credibility with all the confirmations coming from binance itself, I doubt it's gonna be crashing.
BNB is definitely a lot better because people are aware that it's a lower transaction fee, even when ETH is so much low right now. It's a long term idea, even if we see ETH being cheaper one day, it doesn't mean it will stay that way and fundamentally it won't be possible for it to be lower for a long term ever.
This means if you build your project on top of BNB, even during the highest peak bull periods, we are going to see BNB being like 1-2 dollars at most and nothing more. This of course comes with some disadvantage which is the fact that ETH is decentralized whereas BNB is centralized and that's the issue. I believe that ETH still worths it because of being decentralized.
