Everytime Binance is attacked, BNB holders are worried. However, could Binance be really shut down? In theory, yes. But in practice, the worst that can happen to them is to have to restrict some of their services, for instance the tokenised stocks.
What does it mean for Binance coin BNB? This coin has not been more affected by the bear market than most of the other coins. It even behaves better than most of them. Furthermore, Binance regularly burn some BNB, e.g. more than USD 300 million this weekend, what maintains the value of the coin. The Binance Smart Chain is also a positive factor, although there is a fierce competition with Polygon and Harmony.
What's next? Binance will continue to exist as a major centralized exchange for a few years at least, but with more and more restrictions. BNB will continue to be used a lot, e.g. for the payment card of Binance, or for the BSC, or for the launchpad on Binance. However, due to the risks in Binance, you'd better keep your BNB on the BSC rather than on the centralized exchange, and do not bet only on BNB. There are other excellent coins or tokens like ETH, MATIC or Harmony ONE...
