I agree with you in most of them but disagree with you on ETF volume because investors in Bitcoin Spot ETFs are not retail investors. They are big and institutional investors most likely but Bitcoin Spot ETF money flows do have big effects on the market in general and can affect retail investors too.

We can use some on chain indicators like addresses with small balances that can partially represent retail investors.

Charts for addresses with balances about 0.01 BTC and 0.1 BTC + can be good to see recent actions from retail investors.
