I have a friend who is over 50 years old, whom I met 15 years ago at an offline conference. He is a very legendary and interesting guy, and I usually call him "Uncle." When he was young (around high school), the girl he loved suddenly passed away, which became an insurmountable hurdle in his life, and he remains unmarried to this day. He told me that losing a loved one so suddenly is a painful feeling, and he doesn't want to experience it again. He often writes things, including poetry, and he keeps himself very tidy; he looks a lot like Wang Shi. He lives alone in his big house, which is simple and unadorned. Over the years, I've gradually helped him buy some mainstream cryptocurrencies. The first time was when Ethereum was $900, which was around 2018. This May, he bought some $ETH and $SOL. Over the years, he has held onto them, so he has always made a profit. He says the real magic of the crypto world is something I also feel happy to help my friend experience. Today, I told him that in the next five years, ETH will reach 100,000 RMB each, or even higher. He never doubts it. We haven't seen each other for a few years. He has invited me to visit him many times, but I haven't been able to go. This year, I plan to finally meet Uncle.
