Community-created play-money prediction event.
Resolves to the range containing the closing price of Bitcoin (BTC-USD) on Coinbase Exchange for Tuesday, October 20 (2026-10-20), UTC: the close of the public one-day candle that starts at 00:00 UTC on 2026-10-20, which is the last trade before 00:00 UTC on 2026-10-21, as published at api.exchange.coinbase.com. Each range includes its lower bound and excludes its upper bound. The ranges were set around the Coinbase price when the market opened. Trading closes when 2026-10-20 begins (00:00 UTC). The market resolves 15 minutes after the day ends, and the proposed result can be challenged for a few hours before payout. If Coinbase Exchange publishes no valid candle for the day, or the data is unavailable for 72 hours after trading closes, the market is voided and credits are refunded. Later corrections are not applied.
