Back in 2017, my friend Jake was the quintessential skeptic when it came to cryptocurrencies. He'd laugh off any mention of Bitcoin, calling it "funny money" and "a passing fad." One evening, over beers, I showed him my modest investment in Ethereum, which had more than doubled in value in just a few months. Jake's eyes widened, but he remained unconvinced. Fast forward to 2021, and Jake, now a fervent crypto enthusiast, admitted he spent a sleepless night setting up a crypto wallet and buying his first Bitcoin after our chat. Today, he's the guy at parties who corners you to talk about blockchain technology and decentralized finance. Funny how things change!
