Five years ago, on the day of 312, the epidemic had just begun. In early spring, Beijing saw light snowfall in the morning. In the morning, I looked at the market and thought the exchange was broken, so I continued to sleep. At that time, I firmly believed that BTC and ETH would definitely usher in a bull market, it was just a matter of time. Just like a teenager, no matter how many setbacks he encounters during adolescence, he knows that it is a part of growth and that there is infinite beauty in the future. To reminisce about the early spring snow is to reminisce about the youthful cryptocurrency market at that time.
