How to enable wagering/prediction in dota 2?

Wagering

This is something that can only be done with the Winter Battle Pass.

This allows players to bet, using tokens*, at the beginning of games. If they go on to win the game they will obtain battle points, which level up the Winter Battle Pass.

_{*Players get given 1000 tokens each week to bet with.}

Predictions

There are currently two ways players can make predictions on games:

• Using the Assured Victory Shout, which was obtained from the, no longer obtainable, International Compendium 2014. Or,
• Using charms for the chance to win a treasure* after 3 successful predictions. These are currently obtained by purchasing them from the store / market place, such as the Charm of the Autumn Flurry.

_{* From some charms it was possible to get Arcanas or coins, but are no longer obtainable.}

Wagering is something which compendium owner can do. Compendium allows a person to bet and win points along the game. These points level up your compendium and you receive your awards accordingly. Current compendium in dota 2 is winter battle pass.

Predictions is something which a gem owners can do. Valve often releases prediction gems in which when you win 3 times you get a treasure.

Make sure you buy compendium or gems to enable wagering or prediction.

Note:- gems can also be obtained when s person recycles 10 items.

About wagering, you have to own the battle pass in order to wage your points. Then, you can wage after hero selection.

About predict, you have to recycle a few of your items to obtain an item that will allow you to predict, or you can buy the item at the store.

Just buy the compendium, and you can wager every week 1000 :). The predition is another thing. You can buy compendium here :http://www.dota2.com/international/battlepass
