Today, when I was about to leave after get off work, my pretty female colleague who trades in cryptocurrencies called me. She said, "Bitdong (Brother Dong), come and exercise with me." I thought to myself, it's okay. I might as well exercise and have her accompany me. I agreed immediately. We went to the gym she often goes to. She said she hadn't seen her fitness coach for a week. Just as she was about to ask, she happened to meet a gym staff. So she ran over to ask what happened to her coach. The gym staff had a serious face and pulled her to a small corner. She whispered to her, "Your coach has a heart problem. Just a few days ago, he was playing basketball in the gym. Suddenly, he died of myocardial infarction. He was sent to the hospital but couldn't be rescued." Hearing this news, we were suddenly at a loss. Our mood suddenly became heavy and our mood suddenly fell to the bottom. I also know this coach (the coach is usually in good physical condition, he is only in his 30s and still single). Every time he goes to my beautiful female colleague who trades in cryptocurrencies, he will take the initiative to say hello and chat with me. He also knew that I was trading in cryptocurrencies before, and learned from others that I had some BTC. Later, he suggested that I also find a fitness coach, and I said wait. Now I can't see him anymore. This is what happened to people and things around me. Today's incident has brought me a great shock. Life is so fragile. This made me start to think about trading in cryptocurrencies in the cryptocurrency circle, staying up late to trade in cryptocurrencies, and staying up late to make money (at the end of last year, there was a group saying that a cryptocurrency trader who was playing inscriptions often stayed up late to play inscriptions, and died suddenly. The money was still there, but the person was gone) These habits are definitely not good for physical health, and the harm of staying up late has been ignored in the face of making money and the market. Trading in cryptocurrencies is really good when you make money, and you will be very depressed when you lose money. In the cryptocurrency circle (now the old OGs are very open-minded), it is very important to have a good body and a happy mood. I told these words to my beautiful female colleague who trades in cryptocurrencies. She thought it made sense and said she needed to reflect on it and adjust her status in the crypto industry.
