i find it very dishonest that this has always been advertised as "decentralized" exchange while it clearly is not. additionally one of the main attributed of a decentralized exchange should be its open source nature where people can review the code and even compile it from the source code on their own. i can't find anything on GitHub so far:
https://github.com/binance-exchange and that is bad.
another issue is that they are using their own token (BNB) a lot which is not good since it gets pumped and dumped a lot and is nowhere near stable!
and finally using it inside a browser may not be the best choice, i prefer compiling an actual app and stay away from javascript as much as possible
