Back in 2013, my friend Jake was one of those tech-savvy guys who always seemed to be ahead of the curve. One night over pizza, he couldn't stop talking about this thing called Bitcoin. He explained how it was a decentralized digital currency and how he had just mined a few using his gaming computer. At the time, I laughed it off and teased him about his "monopoly money." Fast forward to 2021, and Jake is now a millionaire, having cashed out a portion of his Bitcoin holdings. As for me, I still chuckle about that pizza night, but now I pay a lot more attention when Jake starts talking about new tech trends.
