According to blockchain.info, BTC reached a peak rate of $35 in June 2011. According to the data available from bitcoincharts.com, the highest price BTC was traded in Mtgox that month (and until recently, the all-time high) is $31.9099.

What is the reason for this discrepancy? Does blockchain.info give the rate from an exchange other than Mtgox?

  • Not sure but there were a lot of canceled trades occurring back in the day, especially with the fraudulent access to login credentials occurring before Mt. Gox realized there truly was a security breach. Feb 28 '13 at 13:27

    @StephenGornick: Weren't these things some time after the peak? Feb 28 '13 at 14:28
  • Could you point to the page that says this?

  • @NickODell: blockchain.info/charts/…. It's not so visible now, it can be found by searching for "35.0" in blockchain.info/charts/…. May 26 '13 at 19:31

In the past blockchain.info got their prices from two sources: MtGox and Tradehill (though in the meantime they have removed the reference to Tradehill from their description). It could be related to that.

Also other media report a peak rate of USD 33, e.g., http://www.economist.com/blogs/babbage/2011/10/virtual-currencies
