On the binary, a five-cent move over the line pays the same as a $3,000 run. On Skepsis a 1-of-10 band pays about 10x at a uniform prior, because it is harder to hit. Resolution is the Chainlink BTC/USD feed at the top of the hour.
Examples
Example: BTC hourly close
Price where BTC closes the hour, not just up or down.
BTC is at $61,000. A binary market asks whether BTC is above $61,000 at the top of the hour. You think it closes between $60,800 and $61,200, a tight band around here.
