The SEC lawsuit against Binance has caused a major market crash, especially hitting BNB hard. It's worrying, and the future of BNB looks uncertain unless a solution is found. It remains to be seen if governments will have the upper hand in the crypto world.
The short term negative impact of the law suit against binance on BNB is greatly felt and those that are holding bnb are at lose right now but that will mostly affect those that are in for short-term position in the coin and have the liquidation price close this will end their positions at a loss.
But for those that are holding BNB for long-term asset holding, there have nothing to worry about as we are sure that BNB will recover in its price anytime soon when the wave of this crisis dies down and the exchange recovers from that, BNB is a utility coin and Binance is it biggest liquidity provider since BNB is used to pay fees on the instance smart chain.
