How can I convert credits balance into cash balance?

Many many thanks . I got it.

Promoting is marketing or selling whatever product you have, or you wish to sell. Promoting your product is mainly advertising.

What do you mean by promote.

if you have revpages or articles - you can use your credits to promote them.

What is promotional activities? Don't mind please. I am new here. I don't know more about apsense. Thanks for your kind response.

Credits are not convertible to cash. You can only utilize those credits to do promotional activities that require credits.
