What is credits?
Credits are a means of exchanging advertising between channel owners. The credits system is very simple - you place my advertisement, I pay 1 credit for each viewing it.
Where to get loans?
You can earn credits by advertising with other users. To do this, just create a schedule in the "advertising calendar" of your channel, with the option "Allow mutual PR" enabled. In this case, advertisers will be able not only to buy advertising but also to place mutual PR.
Credits can not be bought.
