In 2013, Ethan, a tech-savvy college student, stumbled upon Bitcoin. Intrigued, he bought 5 BTC for a mere $100. His friends laughed, calling it "Monopoly money." Over the years, Ethan forgot about his modest investment as he got busy with life. Fast forward to 2017, a casual news article about Bitcoin's skyrocketing value jolted his memory. He frantically searched for his digital wallet credentials. After hours of digging through old emails and forgotten passwords, he finally logged in. His $100 investment had transformed into nearly $100,000. Ethan's friends weren't laughing anymore; instead, they were all ears, eager to learn about this mysterious world of cryptocurrencies.
