## Questions

**Is SYN funding-rate arbitrage profitable right now?**

Not at $10,000 per side for 7 days: no SYN pair shows a verified profit after fees and order-book slippage right now. Rates change every hour; the live page re-ranks continuously.

**Which exchange has the highest SYN funding rate?**

Kraken at +276.1% a year (0.0315% every 1 h); the lowest is BingX at +7.7%. A positive rate is paid by longs to shorts, a negative one by shorts to longs.
