part due to rumors around China
Are you crazy?

The crash was because of China.
I'd say that OP is not crazy for using the mild terms mainly because Bitcoin did bounce back. The crash, I'd say was not exactly because of China but moreso because of the fearful investors who didn't want to lose their money. They backed out following the news. Because of this, it's possible that OP meant that China was a big factor; but not necessarily the whole of the story.
