resolve every question separeately when the resolution criteria are met for each one individually

Resolution criteria

• Window: January 1, 2025 00:00:00 UTC through December 31, 2025 23:59:59 UTC.

• Underlying: BTC-USD spot on Coinbase.

• Each answer is an independent threshold: Xk means $X,000 USD. That answer resolves YES the first time Coinbase BTC-USD trades at or above its threshold within the window; otherwise it resolves NO at window end. Multiple answers can resolve YES.

• Primary source: Coinbase Bitcoin price/chart (intraday wicks count): https://www.coinbase.com/price/bitcoin. Secondary (for higher-resolution verification if needed): https://www.coinbase.com/advanced-trade/spot/BTC-USD.

• Fallback: If Coinbase BTC-USD is unavailable/delisted for 24+ consecutive hours during the relevant period, use Bitstamp BTC/USD for the remainder of 2025: https://www.bitstamp.net/markets/btc/usd/.

• Conventions: UTC time; USD pair only (not USDT). If Coinbase later corrects/cancels an erroneous print, use the corrected data.

Background

• Bitcoin trades 24/7 and prices vary by venue; tying resolution to a single USD spot market (Coinbase) removes cross-exchange ambiguity.

• Intraday highs (“wicks”) can trigger resolutions; Coinbase’s public chart shows these and is accessible without an account.

• Independent thresholds mean higher hits imply lower ones also resolve YES.

Considerations

• Correlation: If $131k hits, $126k/$127k/$129k/$130k also resolve YES.

• Fast spikes can resolve answers briefly; 1m or tick-level candles on Coinbase/backup venue will govern.

• If Coinbase’s advanced chart requires login, the public price page suffices for confirmation; Bitstamp is only a fallback if Coinbase is down for an extended period.
