$BTC • The most expensive Pizza in history (Pizza Day): In the first year, Bitcoin had no cash value. It wasn't until May 22, 2010, that a programmer named Laszlo Hanyecz used 10,000 Bitcoins to exchange for 2 pizzas (which were worth about 41 USD at the time). This was the first time Bitcoin was used to purchase real goods.
• The disappearance of the creator: By around April 2011, Satoshi Nakamoto sent an email announcing "moving on to other work", handing over the project to core developers and then completely disappearing without a trace. This withdrawal allowed Bitcoin to truly become a community asset, without a leader or manipulation.
