Back in 2013, my friend Jake was an early adopter of Bitcoin. He was always raving about this "digital gold" and even convinced a few of us skeptics to buy some. One evening, over a few beers, Jake told us he had used 10 Bitcoin to buy a pizza. We all laughed, thinking it was a quirky use of this digital currency. Fast forward to 2021, Bitcoin hit an all-time high, and that pizza turned out to be worth over $400,000! Jake took it in stride, saying it was the best pizza he ever had, but the story became a legend among us. It was a stark reminder of how much the world of cryptocurrency can change in the blink of an eye.
