# GameFi Sustainability

BOUNTYKINDS balances its tokens against each other to keep the game economy sustainable.

BOUNTYKINDS uses three tokens, $BKWD, $YU, and $FFE, to circulate the game economy.

The **$BKWD** serves as the **Governance** token and can only be held by the player, not by the developers, making the Player DAO feasible.

The **$YU** token can be used anywhere in the game as a **Utility** token, yet the $YU reward from a day's play is limited.

The **$FFE** tokens serve as **Energy** tokens in the game, and the number of tokens digested per game is determined by the game once played.

The amount of $YU a player earns per day is determined by the total BWP earned from play, so the more a player plays and the higher the level of play, the more it is reflected in the $YU reward.\

This balance between the tokens is what makes the token economy of BountyKinds sustainable and is the core of the game's main token philosophy, **C2E (Contribute-to-Earn)**.
