Sci-Hub is a shadow library that uses different methods to bypass publishers' paywalls and stores more than 85 million papers. Recently, a person named 0xAA donated to Sci-Hub and purchased the Sci-Hub meme coin of the same name. This behavior has caused controversy. Some people accused 0xAA of insider trading, while others believed that donations should be made directly instead of hyping memes. 0xAA said that he wanted to make money, but also hoped to support the operation of Sci-Hub at the same time. The controversial incident has caused great controversy in the Chinese community, and supporters and opponents have different opinions.
