Portfolio Construction for a Mature Crypto Market

The market has changed. Portfolios should too.

The 2017 and 2021 cycles rewarded concentration and speculation. The 2026 market rewards diversification, discipline, and rebalancing. Constructing a portfolio for this environment is a different discipline.

Core allocation

• BTC: 40–60% of crypto exposure. The reserve asset.
• ETH: 20–35%. The settlement and yield layer.
• Stablecoins / T-bill tokens: 10–25%. Dry powder plus yield.

Satellite allocation

• Blue-chip L1s / L2s: 5–15%
• Thematic bets (RWA, PayFi, restaking): 5–10%
• Pure speculation: 0–5%, sized so a total loss doesn't matter

Rebalancing discipline

• Quarterly rebalance to target weights
• Tax-loss harvest during rebalances
• Predefine bands (e.g., ±20% deviation triggers action)

Correlation matters again

Crypto assets used to move as a single beta. That's less true today. Rebalancing captures more value when correlations diverge — as they now regularly do between BTC, ETH, and altcoin baskets.

Risk budget, not position size

Think in terms of contribution to portfolio volatility, not dollar allocation. A 5% position in a 90-vol altcoin can dwarf the risk of a 40% BTC position.

Bottom line

Treat crypto like a real asset class: written policy, disciplined execution, honest measurement. The returns will follow.
