Frequently Asked Questions

Q: What causes sudden spikes in BTC funding rates?Sharp increases result from imbalances between long and short positions amid low open interest, often amplified by centralized exchange margin calls.

Q: How do stablecoin reserve disclosures impact on-chain behavior?Verified reserve reports trigger measurable inflows into DeFi lending protocols within 48 hours, especially when reserves exceed 100% backing claims.

Q: Why do certain altcoins exhibit correlated liquidation cascades?Shared collateral types—like ETH or stETH—across lending platforms create systemic linkage; a 10% price drop in ETH can initiate forced sales across 17 indexed tokens simultaneously.

Q: Is there a correlation between GitHub commit activity and token price movement?Repositories with over 120 weekly commits show statistically significant positive alpha against BTC returns over 30-day horizons, independent of marketing spend.
