Accurately comparing funding rates on crypto perpetual futures requires aligning multiple contract parameters rather than simply lining up headline numbers. Traders must match the underlying asset, contract type, margin currency, and payment interval before drawing conclusions about relative costs or yields. A key distinction often overlooked is separating estimated funding rates from settled rates. Exchange dashboards frequently display projected figures that have not yet been finalized, meaning apparent discrepancies between platforms may reflect timing differences in rate calculation rather than genuine cost variations.
