On this day in 2017, 1 bitcoin surpassed the price of 1 troy ounce of gold for the first time, with BTC crossing $1,268 while gold traded at approximately $1,233. The symbolic "flippening" of gold by "digital gold" was a milestone long anticipated by Bitcoiners. From a fraction of a cent in 2009 to more valuable per unit than humanity's oldest store of value in under eight years -- a moment that crystallized Bitcoin's monetary ambitions for the world.
