BTC COIN-M Inverse Perp Monthly Momentum Long

Hypothesis

A long-term, BTC-margined momentum strategy on the BTCUSD_PERP COIN-M inverse perpetual using daily bars. The strategy is intentionally minimal — a single regime filter, no supplementary data, no pairs, no extra timeframes — to maximize verifiability and minimize overfitting risk. It is structurally distinct from every recent failure (which were 1D/4H/1H USDT-margined directional or contrarian strategies) and from every strategy already in the pipeline (which target USD-M, spot, or pairs). By trading on COIN-M with ~0.06% round-trip taker cost (lowest available among non-options venues) and holding positions for weeks-to-months, the strategy is highly fee-tolerant: only ~3-8 round-trips per year are expected. The thesis is the persistent BTC long-momentum effect documented in cross-asset research, harvested in BTC-denominated terms — useful for portfolio diversification because PnL is naturally hedged against BTC price swings (gain compounds in BTC).
