According to CoinDesk, Ether (ETH) is expected to outperform Bitcoin (BTC) in September and October due to stronger momentum related to a probable exchange-traded fund (ETF) listing, according to a report by crypto market analytics firm K33 Research. The U.S. Securities and Exchanges Commission (SEC) has a final deadline in mid-October to approve or deny the first Ether ETF, with high chances of the product being approved.

K33 senior analyst Vetle Lunde explained that this development could potentially boost Ether's price, noting that Bitcoin gained 60% in the three weeks leading up to the launch of its first futures-based ETF two years ago. Lunde believes that the odds are in favor of ETH, calling it a 'strong relative buy' compared to Bitcoin.

Lunde also mentioned that the market seems to underestimate the potential impact of a spot Bitcoin ETF. He stated that a spot ETF approval should attract significant inflows, creating substantial buying pressure on BTC. However, if the BTC spot ETFs are rejected, nothing changes. Despite September being a historically difficult period for BTC's price, Lunde believes that current price levels provide a buying opportunity for investors with a longer time horizon.
