Set out the vehicles for investing in digital assets and the risks they carry
The idea
Investors can hold digital assets directly or through vehicles. Direct ownership means holding the asset in a wallet controlled by a private key; whoever controls the key controls the asset, and a lost key or a hacked wallet means a permanent loss. Leaving assets on a centralised exchange instead exposes the investor to the exchange's failure or misconduct. Indirect vehicles include exchange-traded products that hold the asset or futures on it, funds and trusts, and shares in companies whose business depends on digital assets, such as miners or exchanges. Each adds its own risks. Futures-based funds suffer roll costs that make returns diverge from the spot price; trusts without a redemption mechanism can trade at large premiums or discounts to net asset value; and company shares add business and equity-market risk. Common to all are extreme price volatility, uncertain and changing regulation, and the absence of cash flows that anchor valuation.
A practice question
An investor holds a digital asset directly in a self-custodied wallet. What is the main risk specific to this form of ownership?
- Losing the private key — correct
- Roll costs on futuresWhy not: Roll costs arise in futures-based funds, not in direct ownership.
- A fund's NAV discountWhy not: A discount to NAV affects fund shares, not a directly held asset.
Control of a digital asset rests with whoever holds the private key. If it is lost or stolen, the asset cannot be recovered.
A harder one
Why may a fund holding digital asset futures underperform the asset's spot price over time?
- Futures ignore the spot priceWhy not: Futures prices do track spot; the gap comes from rolling, not independence.
- Funds must hold cash onlyWhy not: A futures fund holds collateral, but that is not what causes the shortfall.
- Rolling contracts can be costly — correct
When futures trade above spot, the fund repeatedly sells cheaper expiring contracts and buys dearer new ones, and those roll costs erode returns relative to spot.
The hardest tier
An investor keeps digital assets in an account at a centralised trading platform rather than in self-custody. Which risk rises most?
- Loss of the investor's private keyWhy not: The platform holds the keys, so this risk falls rather than rises.
- Failure or misconduct of the platform — correct
- Roll costs from expiring contractsWhy not: Holding spot assets on a platform involves no futures roll.
The platform controls the assets, so the investor becomes a creditor exposed to its insolvency, hacking or misuse of customer holdings.
