Frequently Asked Questions

Q: How do CME Bitcoin futures settlements impact spot market prices?Settlement occurs at 4:00 PM ET using the CME CF Bitcoin Reference Rate. Price deviations exceeding 0.8% between the reference rate and major spot indices often trigger immediate arbitrage-driven convergence within 92 seconds.

Q: What defines a “confirmed” on-chain transaction in Bitcoin?A transaction is confirmed when included in a block that has received six additional blocks built on top. This threshold reflects empirical analysis showing less than 0.1% probability of chain reorganization beyond that depth.

Q: Why do some stablecoins exhibit negative funding rates on perpetual swaps?Negative funding arises when short positions dominate order books due to perceived depeg risk or regulatory uncertainty, forcing long holders to pay shorts to maintain exposure.

Q: How is miner revenue distributed between block rewards and transaction fees?As of December 2023, BTC miners derived 63.2% of total revenue from block subsidies and 36.8% from fees. For Ethereum post-Merge, 91.5% of validator income came from base issuance and priority fees combined.
