(2) I was attracted by the news about the skyrocketing price of Bitcoin in 2017. I remember it was more than 2,000 US dollars at the time, and it rose to more than 4,000 US dollars within a few days (no wonder I misremembered, because I didn’t know how to use an exchange at that time) I was so excited that I found my notebook (a note-taking notebook) and wanted to get back the more than eight bitcoins I had. I was dumbfounded. I have changed three or four computers in the past few years. The computer with the private key initially let my friend I took it away, repaired it, and sold it as a second-hand one. After asking around for information about Bitcoin wallet recovery, I finally accepted that I had lost all my Bitcoins. I didn’t feel anything after losing them. After all, it was easy to get them. My wife always advised me that foreign money was not worth it. He didn't forget to make fun of me when he told me he was going to be poor. Every time I get together with my friends, I don’t forget to jokingly give him the hundreds of thousands he asked for from me, and he sold me the hundreds of thousands. Slowly Bitcoin faded out of my sight again...
