Bitcoin Up or Down - July 20, 7AM ET

Platform comparison

Market context

Bitcoin’s 1-hour candle closing on 20 July at 7AM ET will resolve this market as “Up” if Binance’s BTC/USDT close price meets or exceeds its open. The crowd currently prices this outcome at 100% YES, implying near-certainty of a flat or rising close for that specific candle.

Historically, such extreme implied probabilities in short-term crypto candles often precede subtle reversals when consolidation zones tighten. Bitcoin recently dropped from $122,550 to around $112,226, now hovering near key moving averages (MA7 at $112,595, MA25 at $112,218) that signal a neutral-to-bearish phase [2]. Comparable cases show that when price compresses between $109,800 support and $112,930 resistance, breakout direction becomes volatile, making 100% pricing unusually confident for a single candle.

Traders should monitor the $112,930–$113,000 resistance zone and the $109,800–$110,000 support band, as breaks here often dictate candle closes [2]. Watch for volume spikes confirming breakouts, scheduled macro announcements, and any Binance-specific liquidity shifts that could alter the 1H candle’s close. Recent analysis notes Bitcoin is eyeing a move above $118,500, but short-term pressure remains near the 99-period MA [2][4]. On Polymarket, this contract settles via USDC on Polygon using conditional tokens, with resolution sourced directly from Binance’s finalized 1H candle data.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
