A few years ago, my friend Sarah, a tech enthusiast, decided to invest in cryptocurrencies. She bought a modest amount of Bitcoin when it was priced around $2000. Skepticism surrounded her decision, with many friends and family members questioning the legitimacy and future of digital currencies. Fast forward to 2021, Bitcoin's value soared past $60,000. Sarah's initial investment multiplied, turning her small venture into a substantial profit. She didn't splurge on luxuries but invested in her dream: starting a non-profit to teach coding to underprivileged kids. Her story became a testament to the unpredictable yet transformative power of cryptocurrencies.
