Where could your model of attracting funds be implemented?

Here is one of the use cases for a PCO:

Popular News Website
For a long time, the websites have been seeking a new form of making money, which would balance between the growth of traffic and revenues. It is known that users are not easily convertible to the paid subscription and it is also difficult to convert them through paywall systems. Minter will enable any website to implement a completely different model when by watching ads and generating traffic for free pages, a user will be able to stack coins and later use them to get access to paid content. It will all happen automatically; people will not need to put any of their efforts. If their balance is less than the required amount, it is always possible to suggest topping it up or completing some tasks, such as sharing the article with friends to earn money on their visits. The greater effect will be reached if the websites unite into a single big network.
