1 ok · 4 to watch
  • Watch: Thin at this size35.1 / 85.6 bp
    At $10k entering BingX costs 85.6 bp, fee and slippage, 2.4× QFEX’s.
  • Note: Margin at max leverage$1,000 + —
    QFEX 10x, BingX —. Keep about 2× this so a sharp move doesn’t liquidate one leg.
  • Watch: Payment intervals differ1h / 8h
    Payments land at different times. Close right after the slower leg pays.
    Next 24h at the current rates, on $10k a leg: +$13.20Long QFEX: 24 payments, +$7.20; short BingX: 3 payments, +$6.00.
  • OK: Entry gap works for you+0.201% vs +0.017%
    You short the dearer leg. If the gap goes back to average, the short gains.
  • Watch: Short leg is thinner$944K vs $1.3M OI
    BingX sets your exit cost. Check its book before closing.
  • Note: No points program—
    Neither exchange runs points right now.
  • Watch: KYCQFEX No · BingX Yes
    Advanced KYC to deposit or trade; unverified accounts can only withdraw, up to 20,000 USDT a day. Rules vary by region.
