I think that after chinese pushed the market last week, it's not the turn of western exchange, probably for the "same" reason (not a devaluation though, but weaknesse of the $)
Let me see if I get this: Chinese purportedly bought BTC due to yuan getting devalued rel. USD ($ too damn strong!)
now the westerners are gonna buy BTC because $ too damn weak?
You must'a been to some expensive universities....
