The next crash will happen on China time - for the most part it's still novel over there and they don't have the experience of living through the last 2 big crashes. Who knows when it will happen, but I'd set a watch to UTC+08:00.
This is the interesting thing. It's like the old saying, the bigger you are the harder you fall. I'm curious to see if we do crash, wither it will be double digits or not.
