Back in 2013, my friend Jake was obsessed with cryptocurrencies. He'd often talk about how Bitcoin was going to revolutionize the world. One evening, while we were having pizza, Jake convinced me to buy 10 Bitcoins for $100. It seemed like a fun, albeit nerdy, thing to do. Fast forward to 2021, I had completely forgotten about my digital wallet until a news headline about Bitcoin's skyrocketing value caught my eye. I logged in, and there they were, my 10 Bitcoins, now worth over $500,000! I called Jake, who laughed and said, "Guess pizza night just paid for your retirement!"
