When to Use Each

Use Regime when: You need to know the market regime (bull/bear/chop) for position sizing, entry filtering, or risk management. Best for trading bot developers and quant teams.

Use Glassnode when: You need deep on-chain analytics — NUPL, SOPR, MVRV, entity-adjusted metrics. Best for long-term investors and researchers.

Use Nansen when: You need smart money tracking — whale wallets, token flows, NFT analytics. Best for alpha discovery and following institutional moves.

Use CoinGecko when: You need basic market data — prices, market caps, volumes. Best for dashboards and price feeds.

Use Santiment when: You need social sentiment + on-chain + market data combined. Closest to Regime but with different signal sources.
