Grayscale and Coinbase made progress in their plans to launch an ether spot exchange-traded fund after meeting with the SEC to address concerns about the safety of such ETFs. Grayscale is looking to convert its Ethereum Trust into an ETF, potentially expanding investor access to crypto-based investment options. The meeting included a presentation by Coinbase, which was posted on the SEC's website, and comes after the SEC's recent approval of spot bitcoin ETFs.
