# 🧱 1. Introduction

In FutbolBrawl, the economy is not a background system. It's the core of everything you do.

The economy is zero-sum: every coin you earn came from another player who spent it. No infinite printing, no magic rewards from nowhere. Matches, transfers, bets, everything moves money between players.

Two currencies make this work:

**$GOAL** bridges in  the real world. You buy it with BNB and use it to enter the game economy. Fixed supply, lives on-chain.

**$CASH** runs the game. Everything inside FutbolBrawl costs $CASH: players, bets, fees, training. It flows between players constantly, and the total in circulation depends on how much $GOAL has been converted.

This separation keeps the game playable without constant crypto transactions, while ensuring that in-game value has real meaning.

The goal is sustainability, an economy where skill is rewarded, not one that collapses when the hype dies.
