When did bitcoin first get a dollar price, and where was it posted?
Research question: When did bitcoin first receive a price in dollars, and where was that price posted?
The records give October 5, 2009 as the earliest known dollar price for bitcoin, when the New Liberty Standard exchange posted its rate 236. That rate was 1309.03 bitcoins per US dollar, derived by dividing $1.00 by the estimated production cost per bitcoin from electricity costs and mining output 59, which works out to about $0.000764 per BTC 14. The price was posted on New Liberty Standard's website, on its Exchange Rate page, and archived copies still exist 817. Other sources instead date the first dollar value to October 12, 2009, when 5,050 BTC sold for US$5.02 via PayPal 14, and no primary source confirms the October 5 rate 8, so the exact date is disputed.
