(1) If you are bored and write about my experience in the currency circle, please pay attention. In 2009, I rented a shabby house of six or seven square meters in a relatively prosperous place in the city and opened a The rent in a small shop is only 300 yuan, so I live a boring life day by day. I heard about Bitcoin by accident. At that time, many people on the Internet were selling this thing. Maybe those people are now big guys. I have a strong interest in new things, so I bought a Bitcoin wallet and started my mining journey. But my computer is too broken and I hung up for a whole day without digging anything. So I went online to look for various ways to get Bitcoin. There is a way to click on the advertisements on foreign websites and leave your address to give coins. At that time, I remembered that clicking on the advertisements would give me 0.0. After a long time, I I can’t remember clearly either. The website at that time was as boring as it is now, and there weren't many rewards that could be redeemed. I clicked on it for about ten days without accumulating a single coin. At the same time, the amount of money mined by the computer was very pitiful. I kind of wanted to give up, but At that time, I had a vague feeling that this thing would be something that would change the world in the future. I didn’t know anything else. I only remembered that the promotional poster showed that the value of one Bitcoin ranged from an eraser to a large villa. The penultimate one was a sports car, so I went online to search how to buy Bitcoins. I can’t remember when and which website I bought them from (probably Taobao), and I bought eight of them for 40 yuan. At that time, I backed up the private key and password as prompted, and also wrote the password and address in a notebook. I naively thought that I could retrieve my wallet as long as I remembered the password. Just like this, the days go by without a ride...
