Binance has proved too much already and they are so far the best crypto exchange so their coin is the best exchange coin to hold at this moment but aside for this coin, there are some exchange coins that is also good to hold at this moment.
seeing the development of binance exchanges, of course their products are now something of value. when binance gets better, and the development of crypto also shows a positive thing, of course BNB will have a big price. if you believe in the development of crypto will be better, I feel that the coin is indeed worth having, more so if you use binance as a place of exchange.
