I am not sure I'm sold on this crash. Some alt coins had mental gains and were overdue a crash, but Bitcoin had relatively modest gains over the last weeks and months (by bubble standards).
Also, it seems very China driven. Huge 5-10% spreads between USD and CNY exchanges.
Given that people can't generally cash out over a weekend, there is going to be a lot of cash sat on exchanges too. This makes me wonder what the picture will look like by the times the banks open their doors.
Maybe I am way out, but something just doesn't feel right.
