Crypto

Definition

Crypto assets are blockchain-native tokens — bitcoin and its successors — that trade continuously worldwide with equity- exceeding volatility and a young, shifting market structure. The platform’s scope is deliberately narrow: US-REGULATED ACCESS ONLY (CME futures since 2017, spot bitcoin/ether ETPs since 2024), treated as a high-volatility alternative asset with documented factor structure (Liu-Tsyvinski: crypto returns load on crypto-specific momentum and attention factors, not traditional asset factors) — and with risk mechanics that stress every default the platform’s equity heritage assumes.

How it works / structure

• The regulated access stack (engine-permitted): CME bitcoin/ether futures (cash-settled to reference rates, margined, 1256 treatment — acct-section-1256), spot ETPs (NAV-tracking with creation/redemption, instrument-etf mechanics apply), spot crypto on US-regulated exchanges (crypto-spot-market-structure, with the custody exposure priced — crypto-custody-models), and crypto-adjacent equities (miners, exchanges — equity beta plus crypto beta). Offshore venues and self-custody are out of platform scope.
• The return evidence: Liu-Tsyvinski (2021) — crypto returns are NOT explained by equity/currency/commodity factors; they load on crypto momentum and investor- attention measures (sent-news-social machinery applies natively); volatility runs multiples of equities (drawdowns exceeding 70% have occurred repeatedly — documented, full-history).
• Structure facts the defaults miss: 24/7 trading (no close — “overnight gap” logic inverts; weekend moves land when regulated wrappers are shut — ETP Monday gaps ARE the weekend), fragmented venues with dispersed reference pricing, and episodic correlation to risk assets (near-zero in early samples, strongly positive in 2022’s tightening — regime-dependent, port-correlation-budgets treats crypto as its own driver).
• Halving/supply lore: protocol-scheduled supply events carry heavy narrative and thin peer-reviewed support — labeled folklore-adjacent, replay territory.

When it applies

Alternative-sleeve allocation with vol-honest sizing (at 60%+ annualized vol, risk-fixed-fractional arithmetic produces SMALL weights for any sane risk budget); momentum/attention strategies where the documented factors live; regime diversification theses (with the 2022 correlation exhibit attached); event expression via futures around known dates.

Risk profile & failure modes

• Vol-blind sizing: equity-habit position sizes on a 3-5x vol asset — the mechanical first error; drawdown budgets must price the documented 70%+ excursions.
• Correlation drift: the “uncorrelated asset” case degrades exactly in liquidity-tightening regimes (2022) — diversification claims are regime-conditional here more than anywhere.
• Structure eventfulness: exchange failures, custody breaches, and regulatory actions are recurring (FTX 2022 is the canonical episode) — platform scope (regulated wrappers only) is the mitigation, not an exemption.
• Narrative density: the asset class runs on attention (sent-news-social evidence applies natively) — thesis discipline (falsifiers, dated catalysts) matters more, not less.

Evidence & limits

Regulated-product mechanics are SEC/CFTC-documented; Liu-Tsyvinski (2021) is the peer-reviewed factor evidence; drawdown history is public record. Long-horizon return expectations are contested and the platform quotes none — crypto theses are momentum, attention, flow, or event theses with replay evidence, not store-of-value assertions.

Falsifiable-thesis examples

Illustrations only, not signals:

• “Bitcoin’s 90-day correlation to the Nasdaq will exceed 0.4 during the next Fed tightening cycle (risk-asset regime thesis)” — falsified by the conditional series.
• “The crypto-momentum factor (Liu-Tsyvinski construction) remains positive out of sample this year” — falsified by the replay.
