The price spread pays, funding is against you. KuCoin is 0.022% dearer against Reya than usual: you sell high and buy low (spread +0.058% now, against its 7-day average of +0.036%): +$2 on $10k if it goes back. Holding the pair costs $0 a day in funding at the current rate, which eats that in about 5.0 days. At the pace of the last 3 days (−0.036% in total) that is about 2.0 days.
