What do you mean "was saved by the Chinese exchanges"?
I guess he refers to prices staying above 2,500 dolalrs per coin now
On May, 26 the price crashed massively and went down to 1,800 dollars, and it is assumed that if Chinese exchanges hadn't been allowed to process Bitcoin withdrawals again in early June, the price would have stagnated at those levels or even gone lower. I don't know how genuine is this claim, but the rebound back to almost 3,000 dollars per coin soon thereafter was rather spectacular and should have an explanation (apart from a simple rebound on its own). The Chinese exchanges with their trading volumes surging explain this hike pretty well
