Money pouch

The Money pouch is a storage area for up to 2.1 billion coins. It is used to handle all financial trading, and all coins received as drops or picked up will automatically be placed in the pouch. It functions similar to an inventory slot purely for coins meaning that coins no longer need to be carried in the inventory. You never will lose money that is in the pouch.

If the player wishes, they will still be able to keep coins in their inventory.

It was announced in the December 2011 BTS, and released on 6 December with the batch 3 update.

When you complete an achievement, you will get money in your Money Pouch.
