A few years ago, my friend Sarah, a tech enthusiast, decided to dabble in cryptocurrencies. She bought a modest amount of Bitcoin when it was hovering around $600. Skeptical friends laughed, calling it "monopoly money." Fast forward to late 2017, Bitcoin skyrocketed to nearly $20,000. Sarah's modest investment had turned into a small fortune. She didn't sell at the peak, but she did cash out enough to pay off her student loans and take a trip to Japan. She still holds onto some Bitcoin, now viewing it as a long-term investment. Sarah’s story is a testament to the unpredictable yet thrilling world of cryptocurrencies.
