It's interesting that the result is 50/50 because in reality the answer is probably yes and no. They are good for bringing more people, institutions into bitcoin and for making it more difficult for anti-bitcoin politicians to invoke severely onerous regulation. That being said they are bad for centralization, self custody and give the US gov a pathway to exert influence over a meaningful portion of the bitcoin supply.

I think they will be a net benefit initially but if they become very popular and a large portion of Bitcoin supply is held by ETF funds it will be long term negative.
