Binance coin is a token from Exchange Binance itself, created for usability in its complex ecosystem: for example, rate discounts and trades. In addition to Binance being the largest exchange in my view, it also has a DEX, meaning it is a diversity of products involving its token, making it valuable and critical to its strengthening, BNB token beyond is listed on its own Binance Exchange and DEX, is still listed on various exchanges around the world. A certainly reliable token that has a great future ahead !!
