Notes & how to use this table
- Point-in-time (PIT) backtests: Prioritize Glassnode, The Tie, Coin Metrics for PIT-safe histories; avoid look-ahead bias.
- Fast signals: For minutes/seconds, combine Twitter/X stream, CoinGlass funding/liqs, CryptoQuant block-level flows, and CoinAPI/Kaiko L2.
- Custom alpha: Use Dune SQL API to mint proprietary metrics and Nansen for labeled wallet triggers; fuse with Amberdata/Kaiko derivatives edges.
- Budgeted core stack (example): The Tie (sentiment/news) + CryptoQuant (flows) + Kaiko or CoinAPI (market microstructure). Add Alternative.me and FRED for regime filters.
