Back in 2013, my tech-savvy friend Jake couldn't stop talking about this new thing called Bitcoin. At the time, it felt like he was speaking another language, but he was convinced it was the future. He spent hours mining Bitcoin on his gaming PC, which I thought was just an excuse to play more video games. One day, he bought a pizza with 10,000 Bitcoins to prove it could be used as real money. We laughed and joked about it for years. Fast forward to 2021, Bitcoin's value skyrocketed, and Jake's 10,000 Bitcoin pizza was suddenly worth hundreds of millions. That was the most expensive pizza ever, and it taught us all a lesson about the unpredictable world of cryptocurrencies.
