it will be easier to explain with the help of an example: one Girl, who is greatly interested in K-pop, uploads her professional opinion about a new music video of a popular idol on her blog, and she has a lot of followers. Since it is a hobby of hers, she cannot make any money from running her blog. However, in a community based on Exa Media Platform, she can get EXA coin based on the evaluation and comments of her followers, and some follower may ask for an evaluation on his favorite idol’s music video and give her coins for a present. Also, if she sets up the content so that it reveals an ‘Idol Goods’ advertisement, she can get more additional advertisement coins based on the number of views.
