If a thing, you can use unlimited multiple times, then he has no value. Users will not cherish it.
Considering this reason: The rewards of 9CBS will reduce unlimited rewards, such as the current Samsung users can send 300 points of posts.
If this is changed, the user can send 10 300 points of post, which will be better.
The principle is that a thing cannot be used unlimited. Should be limited.

The infinite and effective reward should be almost no longer right. Everything is limited.
