BNB do doubt as they are still the top exchange and preferred by many.
I'm not familiar about BGB and its interesting to see this exchange in the top12 in terms of their market cap. Will try to look for more details about this and maybe I can also have this one since Binance is about to be banned in our country, not sure though if it will push through in the next few weeks, its always good to have other option. Exchange tokens most of them are doing good, we should not ignore it as they can also give profit to us.
