Bitcoin Up or Down - July 20, 1AM ET

Platform comparison

Market context

The market resolves based on whether Bitcoin’s price on Binance rises or falls over a single one-hour candle starting 1AM ET on 20 July. A YES share pays out if the candle’s close is at or above its open; a NO share pays if it closes lower. With the crowd assigning 0% probability to an upward move, the implied view is that Bitcoin will finish that hour below its starting level.

Historically, such extreme probabilities often reflect short-term bearish momentum rather than a guaranteed outcome. Recent 1-hour charts on Binance show Bitcoin consolidating after a drop from $122,550, with price hovering near $112,226 and moving averages signalling a short-term downtrend [1][4]. In similar consolidation phases, small hourly reversals are common, yet the prevailing bias has been downward, supporting the market’s current pricing.

Traders should watch for scheduled catalysts that could shift hourly direction, including US economic data releases, Federal Reserve commentary, or major crypto announcements. A recent Binance analysis notes that resistance near $112,930–$113,000 has repeatedly triggered sell-offs, while support between $109,800 and $110,000 remains critical for bulls [1][9]. Any unexpected volume surge or news-driven volatility during the settlement window could invalidate the current 0% implied probability.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
