Deribit BTC Daily-Expiry Defined-Risk Bull Put Spread — Systematic Short-Dated Put-Skew/Variance-Risk-Premium Harvest, Rolled EVERY DAY (DERIBIT Options, ~15-20 Delta Short Put + Further-OTM Long Wing, Coarse Downtrend Skip, 3-Parameter)

Hypothesis

A DEFINED-RISK, single-underlying options income strategy on DERIBIT BTC that harvests the persistent crypto PUT-SIDE variance/skew risk premium. Each day it SELLS a ~15-20 delta short-dated (1-2 DTE) put and BUYS a further-OTM put wing (a bull put / put-credit spread), collecting net premium, rolled DAILY. Engineered around the two things that keep killing options books here: (1) DATA-WALL — prior weekly/biweekly/monthly VRP books produced ~12 trades and died 'unmeasurable'; a DAILY roll produces ~400-600 spreads for real statistical power; (2) NAKED SHORT VOL — prior no_edge/risk_reject deaths were undefined-risk straddles/cash-secured puts; the long wing CAPS tail loss. Distinct from the abandoned ETH post-flush spread (which gated 90% of weeks away) and from the in-pipeline weekly NAKED cash-secured put write. Fills the largest venue quota gap (options 6% vs 15%).
