In order to facilitate the item trading and promote Diamond circulation. We are now implementing Diamond Trading mode for Dota2 items.
Note: For Diamond you obtain by converting items, you will need to use them in predictions(Pre-match or live prediction) first before using them to exchange for other items. Diamond you obtain by winning predictions don’t have any limitations.
After the convert is complete, you can visit the prediction page or My VPGAME to check the Diamond balance
