A few years ago, my friend Lisa was skeptical about cryptocurrencies. She couldn't fathom the idea of digital coins having any real value. One day, she stumbled upon an old USB drive while cleaning her apartment. Out of curiosity, she plugged it in and found an old wallet containing 5 Bitcoin she had bought on a whim back in 2011 for $50. The value had skyrocketed to over $200,000! Lisa was stunned. She used part of the windfall to pay off her student loans and took a trip to Europe. Now, she's a crypto enthusiast, always keeping an eye on the market. That dusty old USB drive turned her into a believer overnight.
