Resolution criteria

• YES if the CoinDesk Bitcoin Price Index (XBX) strictly exceeds $130,000 at any moment between 2025-12-01 00:00:00 and 23:59:59 Beijing time (UTC+8). For avoidance of doubt, the equivalent UTC window is 2025-11-30 16:00:00 to 2025-12-01 15:59:59. Primary source: CoinDesk Indices XBX price page (updates once per second). Backup display: Google Finance ticker “CDIXBX.” (indices.coindesk.com, ir.theice.com, google.com)

• If the XBX feed is unavailable or clearly erroneous at resolution time, resolve YES only if at least two of the following spot USD markets print a trade > $130,000 during the same window: Coinbase BTC-USD, Kraken XBT/USD, Bitstamp BTC/USD (verify via their official trade-history APIs/pages). (coinbase-cloud.mintlify.app, kraken.zendesk.com, bitstamp.net)

• Notes: “超过”= strictly greater than; equals $130,000 does not count. Spot markets only (no futures/ETFs). Clearly cancelled error prints are ignored; asset is BTC (Bitcoin).

Background

• 比特币在2025年8月中创下约$124k的历史高位后回落；路透与多家行情源记录的8月高点在$124k附近（例：8月14日高至约$124.4k）。截至9月初，现价约在低$110k区间波动。 (reuters.com, investing.com)

• 选择XBX作为主要裁定源的原因：它是跨多交易所的即时报价基准，被传统金融机构采用（例如NYSE宣布基于XBX开发期权），降低单一交易所异常成交对结果的影响。 (ir.theice.com)

Considerations

• 时区对齐：不少数据网站的“日”线以UTC统计（如CoinMarketCap历史数据），本市场以北京时间的自然日为准；因此给出等效UTC窗口以便交叉验证。 (support.coinmarketcap.com)

• 若需要人工复核备选源：可用Coinbase Advanced/公共API获取BTC-USD逐笔；Kraken公开Trades端点获取XBT/USD逐笔；Bitstamp Transactions端点获取BTC/USD逐笔。 (coinbase-cloud.mintlify.app, kraken.zendesk.com, bitstamp.net)
