A few years ago, my friend Jake, a tech enthusiast, decided to invest in a then-unknown cryptocurrency called Ethereum. At the time, Bitcoin was the talk of the town, and most people hadn't even heard of Ethereum. Jake, however, was fascinated by its potential for smart contracts and decentralized applications. He bought 100 ETH at just $10 each, despite his friends mockingly calling it "Jake's folly." Fast forward to today, Ethereum is one of the leading cryptocurrencies, and Jake's investment has turned into a small fortune. His once-skeptical friends now eagerly seek his advice, and Jake's story has become a lesson in the unpredictable yet rewarding world of cryptocurrencies.
