Ether (ETH) will outperform bitcoin in September and October, according to crypto analytics firm K33. Given the high chances that the U.S.’ first ether ETF will be approved in mid-October, investors can ride the momentum that will drive ETH as the deadline approaches, according to senior analyst Vetle Lunde. September is a historically difficult month for BTC, having recorded negative returns in that month every year since 2016. The odds, therefore, are “stacked in favor of ETH,” Lunde said, citing the 60% gain that bitcoin made in the three weeks prior to its first U.S. futures-based ETF winning approval in 2021.
