Bitcoin ETF, how it could be bad in the long term.

The Bitcoin ETF is what all the big discussion is about in the crypto world these days but there are people who think it would be bad long-term for the cryptocurrency. The voiced concerns are market control by Wall Street and big name players and increased centralization of Bitcoin. I think I agree with them overall but a lot of my fears would be alleviated if the ETF’s that were approved would settle in Bitcoin instead of Cash, which could results in more manipulation. People against a Bitcoin ETF think bitcoin would function well in the long-term without the need for instruments like ETF. I don’t disagree with them but it would take a lot longer without such things like ETFs.
