Two pizzas arrive at Laszlo Hanyecz’s doorstep in Jacksonville, Florida, marking the first known purchase of tangible items with the cryptocurrency. The pair of pies — valued at $25 — set Lazlo back 10,000 bitcoins. This amounts to the first concrete valuation; the price of one bitcoin is worth approximately $0.0025. (The 10,000 bitcoins spent on that pizza would be worth about $150 million at today’s exchange rate.)
