How this settles
Resolves YES if the 60-second simple average of CF Benchmarks' BRTI ending just before the later settlement time is greater than or equal to the 60-second simple average of CF Benchmarks' BRTI ending just before the earlier settlement time on the settlement date.
- CF Benchmarks BRTI — not spot price — Resolution uses CF Benchmarks' Bitcoin Real-Time Index (BRTI), not any exchange's spot price; discrepancies between BRTI and exchange prices can affect whether the position resolves as expected.
- 60-second simple average, not a single print — Each reference price is the arithmetic mean of sixty one-second BRTI values, so a brief spike or dip in Bitcoin's spot price in the final seconds may not move the average enough to change the outcome.
- "At least" makes equality resolve YES — The comparison is ≥, so if both 60-second averages are identical the contract resolves YES, not NO — a tie favours the long side.
- Seconds window is "before" the timestamp — The 60 seconds used are those immediately preceding each named time (not including or starting at it), so the exact second-boundary definition matters when the averages are close.
These are the rules for the whole series — every contract in it settles the same way. Full KXBTC15M settlement rules →
