Funding pays, the price is against you. Extended is 0.139% cheaper against Bybit than usual: you would sell low and buy high (spread −0.139% now, against zero (this spread has no 7-day history yet)). If the spread goes back, that is −$14 on $10k: about 15 hours of funding at the current rate (+$22 a day).
