2). Orders of each currency can be put on the ads list for up to six advertisements simultaneously.
3). The available balance is less than the minimum order limit.
4). When the OTC trade volume reaches the daily limit, the published advertisements will be hidden (including the total amount of completed + in progress + appealing orders), and the unpublished advertisements cannot be put on the ads list.
