A few years ago, my friend Dave decided to invest in Bitcoin. Skeptical but intrigued, I watched as he poured his savings into this digital currency. One evening, while we were out for coffee, Dave excitedly showed me his crypto wallet; his initial $1,000 had ballooned to $10,000 in a matter of months. Fascinated, I asked him about his strategy. He laughed and admitted he had no idea what he was doing, just following online forums and gut feelings. Fast forward to a market crash, and Dave's $10,000 plummeted back to $800. Over that coffee, we learned a valuable lesson: cryptocurrencies are a wild ride, not for the faint of heart.
