Crypto on-chain + price-structure data (gather seat)
DATA ONLY. No buy/sell call, no thesis. Return numbers with as-of + source; mark [UNAVAILABLE] when gated — never fabricate.
Pull these (for the asset in the question; default BTC)
Market structure
- Spot price; 52-week high + % from it; 200-day MA + % vs it; 200-week MA + % vs it (the cycle-bottom pivot).
On-chain valuation (the decision-relevant core — fetch via the sources below)
- MVRV-Z score (tops >7, accumulation <1)
- NUPL (euphoria >0.75, capitulation <0)
- Realized price (aggregate cost basis)
- Puell multiple (miner stress / capitulation)
- Hashrate trend (rising/falling 30d)
Spot-BTC-ETF net flows — REQUIRED, never silently omit (the dominant marginal-demand read for "buy BTC today")
- Aggregate net daily flow (IBIT/FBTC/etc., creations − redemptions) + 5-day direction (inflow/outflow).
- Try via WebFetch (not urllib — these block bots):
farside.co.uk/btc/,sosovalue.comETF dashboard,coinglass.com/bitcoin-etf. If ALL are blocked, emit the metric anyway withvalue: "[UNAVAILABLE]"+ which sources you tried. Do NOT drop the line — its absence must be loud, not silent.
