What bitcoin is

Every year on May 22, bitcoin enthusiasts celebrate Bitcoin Pizza Day – the day Laszlo Heinitz exchanged 10,000 coins for two pizzas.
As of this writing, Laszlo would have $973,903,500 worth of BTC. It’s hard to imagine how much you can buy with that kind of money. For example, you could own one of the most expensive islands in Thailand, Rangyai, which is worth $160 million. And in addition, you could buy a Boeing 747-430.
