At the end of 2019, when the Chinese New Year was approaching, I saw an old colleague posted a circle of friends (Chinese New Year is coming soon, please invite the aunt to come to the villa to clean up). I called him to ask what he was doing recently. He moved to a big villa (Shenzhen Longgang Park Land) in the most upscale community around. He said that Chinese New Year is coming soon, and it is good to watch the aunt cleaning up. I said come to my place and share what you have done in the past two years. He came a while later and said a lot of things that I couldn’t understand. He asked me to download a wallet and let me borrow words. He said that if you have spare money, just buy BTC and don’t care about it. He said that he lost 2 million before and sold all the houses. In the end, he didn’t sleep for a few days and now he has made it back. He also had 1,000 BTC at the time, and said that now is a low price to buy. I bought one with half-belief at first. It was more than 3,000 US dollars at that time. I held it in my hand and didn't see any movement. I sold it to chase junk coins. At that time, new coins were popular. I rushed to get the chance to be cut. My colleague also issued his own coins and asked me to play with him. I didn't believe him. He has a Weibo account (Principal Long) and is a little famous in the B circle. You can find it online. After half a year, I slowly forgot about the small loss. Later, I heard that he was scolded by many people and went abroad. It seems that he also made a lot of money. Just 1,000 BTC is almost 1 billion, and he cut a wave of leeks. At the beginning of 2025, I heard on the news that B reached 100,000 US dollars. I thought about seeing if there was any surplus in my wallet, which could be more than 30 times. As a result, there were only a few altcoins, which were worthless. It's too late!
