Investors looking to trade the KXBTC contract are facing a unique pricing mechanism that differs from standard spot markets. Rather than settling on a single point-in-time price, this derivative is designed to track the average value of the Bitcoin Real-Time Index (BRTI) over a rolling 60-second window.

According to the contract's underlying data, the BRTI index is currently valued at $74,685.25. The settlement calculation for this contract relies on a simple average of the last 60 one-second values recorded by the index. This structure means that the final price at which the contract settles is determined by the arithmetic mean of the index over the final minute of the trading session.

Because the settlement price is an average of the previous 60 seconds, the contract price is expected to remain relatively stable and closely aligned with the current market rate of $74,685.25, assuming no extreme volatility within that specific one-minute window.

What would change this read

This outlook assumes the average price of the BRTI index over the last 60 seconds remains consistent with the current price. However, if the index experiences sharp volatility or a sudden trend reversal during the final minute of trading, the average could deviate significantly from the current snapshot, altering the settlement outcome.
