Foolish, copied without missing a word

My 3,000 yuan turned into 30,000. I have never seen so much money in my life, so I emailed my professor from back then asking what I should do. He was surprised that I was also trading cryptocurrencies because in 2013, very few people knew about Bitcoin, even abroad, it wasn't regarded as a good thing. He told me to go to his office and explained a lot to me, mostly his views on the development of this technology. Many of the technical terms I didn't understand at all; I just felt it was impressive. He never mentioned the price of cryptocurrencies; I was more concerned about the price than the technology. It seems that foreigners value value investing more than speculation. Ever since that meeting, I started researching blockchain in the library, but there were very few books about Bitcoin at that time, and the library basically had no relevant books. I could only translate the white paper word by word, and many technical terms I didn't understand, so I had to push through to the end with only a partial understanding.
In 2014, I stumbled upon a person named Chang Tie on Douban, who wrote a book called 'Bitcoin: A Illusory Yet Real Financial World'. This book gave me a comprehensive understanding of what Bitcoin is, which provided a belief foundation for my later investment in Bitmain. Of course, the worldview was formed, but the methodology had issues. At that time, I joined a QQ group, and the so-called 'jumping gods' in the group were no different from those on Weibo today, endlessly chasing rises and falls. Eventually, I reduced my holdings from about 10 Bitcoins to 5. So I began to ponder the once esoteric theory of entanglement. Until today, I have only scratched the surface because the market is truly unpredictable and full of variables. To achieve consistent success, one must monitor it constantly. That period was the most painful time in my cryptocurrency trading career. Perhaps many of my group friends are also experiencing this period, having invested tremendous effort just to grow 5 Bitcoins into 12. Of course, during that year, the price dropped from $800 to $500; even though I earned some coins, my principal still decreased.
