It allows the user to earn money again every time the answers to the questions asked or the results of the surveys are viewed. The User/Company conducts a survey of 10 thousand IT employees and Computer engineers about the best antivirus program and rewards 1000 tokens for the results. This means 0.1 Tokens per user. Then, 10 tokens are charged to anyone who wishes to view the results of this survey. This fee is given to the owner of the survey, that is, to the person who created it first. Thus, the cost of the next user is greatly reduced, and after a while, the cost of the first person who asks the question is amortized. Even higher earnings can be achieved over time, depending on the popularity of the survey. This is called knowledge mining.
