Tournaments have their own virtual currency – ₮. All trading operations on the tournament account are held in that currency, and it is not related to the currency of your real or demo accounts. The account’s starting balance is determined by the conditions of the tournament (in most cases, it’s 100₮). After the tournament is over, the remaining balance in ₮ currency and the tournament account disappear. And the prize fund is divided among all the participants who took prize places.
Note. When participating in a tournament, you can only use real funds to sign up and make rebuys.
