In 2010, a programmer accidentally came across Bitcoin, when the price of Bitcoin was almost zero. Out of curiosity, he mined 500 Bitcoins with an ordinary computer. Because he felt that these digital currencies had no practical use, he stopped paying attention and continued to be busy with his work.
A few years later, when the price of Bitcoin soared to thousands of dollars, he remembered his early Bitcoins. When he was excited to retrieve them, he found that he had formatted the hard drive containing the Bitcoins and even threw it away. At that moment, he realized that he had missed a huge fortune.
