binance has an exchanger and currently has a bsc network, with the same development as the exchange it has, bsc is now a favorite network for new projects, so it is more widely used. and if these improvements continue and provide even better service then I think $1k for bnb is very possible
I wouldn't call it "favorite" since there are still so many other tokens that start in ETH, but it is definitely top 2, most projects either go with ETH or go with BSC, and yes there are other chains that projects pick but these are the top two by a big big margin. This is why I believe that we should not be focusing on something that is based on success that it had, but success it could have.
We have seen many projects on BSC so far, and exchange is by far the best one I have seen and my favorite, but that is what happened, it is what we can call it "so far" and I wonder if it will be that good in the future as well. Because you are not paying for what it was, you are paying for what it could be, and you need to know if it will good or not in the future as well to decide if you want to invest. If you think it will continue to be astonishing then you should invest.
