The price spread pays, funding is against you. Extended is 0.171% dearer against BloFin than usual: you sell high and buy low (spread +0.171% now, against zero (this spread has no 7-day history yet)): +$17 on $10k if it goes back. Holding the pair costs −$1 a day in funding at the current rate, which eats that in about 33 days.
