I was extremely busy in college and squeezed my time frantically. I was so busy that I dozed off in class. I had to work multiple times and did various tasks, and my job was part-time. I worked two or three part-time jobs at the same time, and whenever I had free time, I would earn money that people liked or didn't like. Various attempts could improve my ability to withstand pressure. When I graduated, I earned an annual salary of 100000 yuan, and then did some side jobs such as investing, tinkering, and shearing sheep By the way, the first BTC I bought was priced at 3000 yuan per piece And the last question, please refer to the picture
