In my opinion, the resigning of CZ and paying the fine of more than 4 billion dollars to DOJ is not bad news, at least not for us, because we are not paying that money. But if they, by they I mean CZ or Binance, failed to comply with DOJ or failed to comply with the fine imposed then Binance might have to face total seizure which would lead to a big disaster.
I would say, we are saved from big bad news, and they handled a big case greatly even if the market faces a small downtrend but sacrificing less is better than losing more. Even many people made a lot of money by shorting BNB when this news came out. I saw the downtrend of BNB with my own eye when this news came but I did not make any short trade.

But there is no doubt that bad things bring good things also, like after every China ban or opposition of BTC, it emerges better than before. I think BTC likes challenges and wants to test its limits with bad news. Just kidding, it is not BTC that likes to test instead it's the people behind it who are using it and supporting it, adding to the BTC network and market cap, they are the ones facing challenges.
