If you sell them, no one will accept them. You can only cheat the people who collect them (which is why so many people go to Zhihu to advertise for them). 2. Collect personal information and sell it. Do you know that you need a name to register this website? Identity card number, mobile phone number and other information for real-name authentication, but also threaten you to provide false information, give you a title+public security punishment, which is a common routine for the government to support ethnic cooperation and pyramid schemes. 3. Prepare for the following charges. Of course, there is no need to pay now, but when the project side accumulates enough people, some charging items will be launched. For example, let you spend money to buy a so-called "mining machine" with higher computing power, so that you can produce money faster.
