Totally hear you there about principle. Do you have any historical data which shows other exchanges/market rate(s) going above $500 USD?
Thanks,
A lot of historical data is available, Bitcoinwisdom and BitcoinCharts has Bitstamp, itBit and Bitfinex crossing $500 USD on November 4th. Coinbase hit 499.85, so obviously close. Bitpay apparently uses a basket, but its confidential so we'll never know what weighting each exchange got.
