As answered by people managing JavaScript Operator Lookup and BTC War.
BTC War's answer:
BTC War uses React and TypeScript for the interface, Three.js/WebGL for the six 3D battlefields, and a Vite/vinext build pipeline. Live inputs come from disclosed Binance Spot aggregate-trade streams plus REST ticker data and periodically refreshed visible-depth snapshots, relayed through a small Node service and Cloudflare edge delivery. The battlefield actors and effects are synthetic visual metaphors rather than literal trader, wallet, position, liquidation, or order identities.
BTC War's answer:
BTC War is for crypto-curious users, educators, data-visualization practitioners, Three.js/WebGL developers, and market-structure learners who want an intuitive view of relative BUY-versus-SELL activity. It is not intended for users seeking custody, deposits, gambling, guaranteed returns, price predictions, or trading signals.
BTC War's answer:
BTC War separates observed market data from synthetic presentation. It consumes disclosed Binance Spot aggregate-trade streams, REST ticker data, and periodically refreshed visible-depth snapshots for nine markets, then turns relative BUY-versus-SELL activity into six switchable Three.js scenes. It is free and read-only: no account, wallet connection, deposit, custody, order execution, gambling, prediction, or trading signal. Its public methodology and machine-readable snapshot expose source attribution, timestamps, freshness, schema, and integrity metadata.
BTC War's answer:
Choose BTC War when you want to observe live spot-market activity as an interactive visual system rather than as another chart or signal dashboard. It combines nine disclosed Binance Spot markets, six switchable 3D scenes, a timestamped price snapshot, and explicit methodology in one free browser experience. It is designed for exploration and education, not investment advice or order execution.
BTC War's answer:
BTC War began as an experiment in making fast, abstract crypto market events easier to inspect without pretending that animation is literal market truth. The project therefore keeps a strict boundary between observed Binance Spot inputs, derived state, and synthetic battlefield effects. That separation now extends to its public methodology, machine-readable market snapshot, schema, timestamps, and freshness controls so people and AI systems can verify what each value means.
