That is one of the most famous transactions in Bitcoin history. A user initiated a bold proposal on a forum: exchange 10,000 Bitcoins for two pizzas. At the time, this idea didn't seem crazy — Bitcoin was still very young, and market liquidity was limited. Soon, someone responded to the offer. The parties reached an agreement, the Bitcoin transfer was confirmed, and the pizzas were delivered. This seemingly ordinary exchange of goods became a historic witness to the application of cryptocurrency in daily consumption. If we look back at the current prices, the cost of these two pizzas is simply incalculable. But in that era, the significance of this transaction was that it proved Bitcoin could be genuinely circulated, transforming from a virtual asset into a real means of payment. This story also reminds us that every early attempt in the market could mark the beginning of a new era.
