This paper guides fiduciaries through the process of constructing a digital asset investment mandate, emphasizing risk-adjusted returns, liquidity, volatility, and diversification. With Bitcoin ETFs now offered by major institutions like BlackRock and Fidelity, fiduciaries must determine how assets like BTC and ETH fit into client portfolios. Key considerations include yield generation through derivatives, low correlation to traditional assets, inflation hedging, liquidity preferences, time horizon, and real-time reporting. Fiduciaries are also advised to benchmark performance thoughtfully—against the S&P 500, BTC spot, or broader indices like CCi30—based on the investment objective. Given the asset class's complexity, the report recommends partnering with regulated experts like Two Prime to deliver systematic, risk-managed exposure to digital assets.
