The Coinbase cryptocurrency exchange plans to provide custodial storage services to most Ethereum-ETF issuers.

Brian Armstrong, director of the trading platform, said that Coinbase is the custodian of assets in five of the eight applications for the creation of Ethereum-based spot exchange-traded investment funds filed with the U.S. Securities and Exchange Commission (SEC).

He noted that the release of the Ethereum-ETF had a positive impact on the industry and attracted capital from private and institutional clients, which turned out to be beneficial for Coinbase.

"All organizations are starting to store cryptocurrencies, this asset class will become part of every diversified investment portfolio. The financial system officially accepts virtual currencies," Armstrong said.

However, users of the Polymarket betting platform express doubts about the imminent approval of the Ethereum-ETF. The probability that the SEC will approve the issue of these derivatives before May 31 is estimated at only 39%.

The skepticism of gambling members of the crypto community is explained by the weak bullish trend in the Ethereum market. One Polymarket user drew a parallel with bitcoin and suggested that the coin's exchange rate would rise much faster if investors knew about the imminent approval of the ETF.
