I had thought of Casa in comparison to Bitwise. Casa probably has to deal with Ethereum custody directly for their products, so I can see why it's turning into a huge burden for them. I remember that nostr:npub17u5dneh8qjp43ecfxr6u5e9sjamsmxyuekrg2nlxrrk6nj9rsyrqywt4tp has done a lot of work into Ethereum self custody and node running.
Bitwise would get someone like Coinbase to do that part for them, so it makes sense for them to wrap an ETF around it like they did with Bitcoin. Is this on the right track, nostr:npub1jpvsahpy0vgq7gu8nfqjkeskce0gwjk8jpss590xkvjh5xxe4epsruqgsz?
