A few years ago, my friend Alex decided to dip his toes into the world of cryptocurrencies. He bought a small amount of Bitcoin when it was just $600 per coin, skeptically believing it might just be a passing fad. Fast forward to late 2017, Bitcoin's value skyrocketed to nearly $20,000. One evening, over coffee, Alex showed me his digital wallet with a grin so wide it could light up the room. “I’m practically a millionaire!” he exclaimed, though his enthusiasm was tempered by the volatile market. Inspired by his success, I invested a modest sum, only to watch the value plummet the next month. The experience taught us both about the incredible highs and lows of the cryptocurrency rollercoaster. Alex eventually cashed out a portion, wisely diversifying his newfound wealth, while I held on, waiting for the next big surge. The world of cryptocurrencies, we realized, is not just about luck but also timing and strategy.
