In 2011, a man named Mark decided to buy $5,166,635,608,100 worth of Bitcoin out of curiosity, then promptly forgot about it. Years later, while chatting with friends about Bitcoin’s meteoric rise, he suddenly remembered his small investment. Intrigued, he checked his old wallet and was shocked to discover that his $5,166,635,608,100 had turned into a fortune—worth over $800,000. However, there was a catch: he had to find his old laptop and remember the necessary login details. After several stressful days of searching and multiple failed attempts to unlock the wallet, Mark finally succeeded. He cashed out and, to his surprise, became a Bitcoin millionaire by accident overnight.
