Bitcoin has transformed from an obscure digital experiment into a global financial phenomenon. In 2010, Laszlo Hanyecz famously purchased two pizzas for 10,000 Bitcoin—a transaction worth billions today. This pivotal moment highlights Bitcoin's extraordinary journey. But what exactly is this revolutionary currency, and how does it work? Let's explore.
