I think he is right by doing that. No matter what he does, people shit on him.
If he had kept the news, people would blame him that he was not sharing it. When he decides to share it, this happens.
He said that the China ban is still just a rumor, yet, he posts something like that without knowing if it's true or not.
"Because it's still a rumor. Nothing official yet."

He shouldn't post something like "China will ban Bitcoin", and then afterwards correct to "China will ban all Bitcoin exchanges" if he is not sure about that. People trust him, and they will believe on his words.
I doubt, that the reason was just his tweet. But nvm. Who is Charlie Lee btw?
What else could have crashed the market?
