ATH = $1242 @ Mt Gox
You cannot count that BS price on Mt Gox when they were ALREADY insolvent and did not payout $$ withdrawals, hence btc price on that exchange was constantly $100 higher since smart people were converting all fiat currencies on MtGox to btc, then withdrawing btc.
The CNY price at the moment reminds me a bit of Mt Gox prices. Bitcoin costs more than $100 more (equivalent) in CNY than in USD, that's pretty weird.
Sometimes the big difference implies China thinks there is a coming Yuan devaluation.
