Back in 2013, my friend John, an early adopter of tech trends, called me excitedly about something called Bitcoin. Skeptical but curious, I watched as he spent $50 to buy 20 Bitcoins. Fast forward to 2017, Bitcoin's value skyrocketed, and John was sitting on a small fortune. He cashed out a portion and bought his dream car, a Tesla. While John's story is a testament to the wild ride of cryptocurrencies, it also serves as a cautionary tale. For every success, there are countless tales of lost digital wallets and volatile market crashes. Cryptocurrencies are a thrilling frontier but tread carefully—it's a rollercoaster out there.
