# CBT - CyBloc Battery Token

CyBloc Battery Token (CBT) is an ERC-20 & BEP-20 token with no fixed supply.

This is CyBall's primary Play-to-Earn reward and utility token.

Users can earn $CBT when performing the following:

* Compete in various PvP modes ([**Exhibition**](/game-mechanics-and-features/game-modes/exhibition.md), [**League**](/game-mechanics-and-features/game-modes/league.md) and [**Tournament**](/game-mechanics-and-features/game-modes/tournament.md))
* Earn revenue from [**CyLoans**](/ecosystem/cyloans.md)
* Rewards for users who perform various activities that help the ecosystem

Users must spend $CBT to enjoy the following features:

* [**Mentoring**](/ecosystem/mentoring.md)
* [**Hire-a-Coach**](/game-mechanics-and-features/game-modes/training/hire-a-coach.md)

## Batteries (In-game Currency)

CyBall’s primary in-game currency is called Batteries. Players can earn Batteries by competing in PvP matches.

Batteries accumulated in-game are technically different from CBT stored on-chain. A user's in-game Batteries get converted into on-chain CBT with a 1:1 ratio when claimed (withdrawn) from the game server to blockchain.
