About 12 years ago, I came across a news article about Bitcoin where a programmer had used it to buy a pizza, which I found quite interesting. I downloaded mining software and, at that time, it was actually possible to mine Bitcoin with a computer, although it required a lot of computing power. My old laptop could also mine, but the software estimated that it would take about a month of continuous use to mine a significant amount. At that time, the price of Bitcoin was around $70 to $80 each. However, I quickly realized that my laptop would become unbearably slow if I continued mining, so I gave up after just a couple of hours.
