1 ok · 4 to watch
  • Watch: Thin at this size18.5 / 16.4 bp
    At $10k entering BloFin costs 18.5 bp, fee and slippage, 1.1× Popdex’s.
  • Note: Margin at max leverage$200 + $200
    BloFin 50x, Popdex 50x. Keep about 2× this so a sharp move doesn’t liquidate one leg.
  • Watch: Payment intervals differ4h / 1h
    Payments land at different times. Close right after the slower leg pays.
    Next 24h at the current rates, on $10k a leg: −$7.32Long BloFin: 6 payments, −$10.20; short Popdex: 24 payments, +$2.88.
  • OK: Entry gap works for you+0.324% vs −0.003%
    You short the dearer leg. If the gap goes back to average, the short gains.
  • Watch: Short leg is thinner$108K vs $2.0M OI
    Popdex sets your exit cost. Check its book before closing.
  • Note: No points program—
    Neither exchange runs points right now.
  • Watch: KYCBloFin Limited · Popdex No
    No ID to trade futures, with no leverage limit, but withdrawals are capped at 20,000 USDT a day until you verify.
