Bitwise has updated its Form S-1 registration statement for its spot Ether (ETH) exchange-traded fund (ETF), revealing a potential $100 million investment from Pantera Capital Management. However, the filing notes that this is not a binding agreement. The Form S-1 is the final step before the ETF can be publicly traded, an event expected to occur this summer. The SEC recently approved filings from eight Ether ETF bidders, but they still require Form S-1 approval. This news coincides with the SEC ending its investigation into whether Ether is a security.
