Crypto SMA vs Fund vs Non-Custodial Managed Account

A crypto fund pools investors’ money into one vehicle you wire into. A separately managed account (SMA) is managed in your name. A non-custodial managed account goes further: assets stay in your own exchange account and the manager gets trade-only access. Each differs on custody, liquidity, minimums, and counterparty risk.

If you hold a serious crypto position (say $100,000 to several million in Bitcoin, Ethereum, or stablecoins) and you want it professionally managed, the strategy is only half the decision. The other half is the structure: the legal and operational wrapper that determines who holds your assets, who can move them, how quickly you can get them back, and what happens if the manager fails.

This article compares the three structures a serious holder or family office actually weighs: the pooled crypto fund, the crypto SMA, and the non-custodial managed account. All three can run the same strategies. Where they part ways is in what can go wrong.

What are the three ways to have crypto managed?

1. Pooled fund. You wire money into a collective vehicle, typically a limited partnership. Your capital is commingled with other investors’, and the fund’s general partner (GP) invests it as one pool. You own units of the fund, not the underlying coins.
2. Separately managed account (SMA). A crypto managed account opened in your name, usually at a qualified custodian or prime broker. The manager trades it under a mandate, but the assets are legally yours and segregated from other clients.
3. Non-custodial managed account. The assets never leave your own exchange account. The manager receives a restricted, trade-only sub-account or API keys: they can execute the strategy, but they can never withdraw funds. This is the model Packed Capital runs: a crypto managed account rather than a fund.

Structure moved to the top of the diligence list after November 2022, when FTX filed for bankruptcy with an estimated $8 billion shortfall in customer funds. Investors in pooled vehicles holding assets on FTX, and lenders like Celsius before it, learned that the custody question decides who absorbs the loss.

How does a pooled crypto fund work — and what are the trade-offs?

A crypto fund is usually structured as an LP/GP vehicle: investors are limited partners (LPs), the manager is the general partner (GP). You subscribe via an offering memorandum, wire fiat or coins in, and receive fund units valued at NAV (net asset value), typically calculated monthly.

A fund earns its keep on breadth. It can diversify across dozens of positions, venues, and strategies that no single account could replicate. It can access deals individuals can’t (SAFTs, locked tokens, early-stage allocations). Administration is professional: an external fund administrator strikes the NAV, an auditor reviews the books, and the GP handles every operational detail. For venture-style crypto exposure, a fund is often the only workable structure.

What you give up starts with the commingling itself: you own a claim on the vehicle rather than your own coins. Liquidity is defined by redemption windows: many crypto funds allow redemptions only monthly or quarterly, with 30–90 days’ notice, and new investors often face a lock-up of a year or more. Fees typically follow the hedge-fund convention of a management fee plus a performance fee (often with a hurdle rate and high-water mark), charged whether or not the strategy suits current markets. Transparency is periodic: you see a monthly NAV statement, not live positions. And counterparty risk is layered: you are exposed to the GP’s operational decisions, the fund’s custodian, and every exchange the fund trades on.

If the fund held assets on the wrong venue, redemption requests can be suspended outright, which is what investors in FTX-exposed funds experienced in late 2022, waiting years for bankruptcy distributions.

What is a crypto SMA, and when does it make sense?

A crypto SMA, or separately managed account, imports a structure long standard in traditional wealth management. The account is opened in your name, usually at a regulated custodian, and the manager is granted discretionary trading authority over it.

Pros:

• Segregation. Your assets are not commingled with other investors’. If another client redeems or the manager’s other accounts blow up, your account is unaffected.
• Transparency. You can see your own positions, often daily and sometimes in real time, instead of waiting for a monthly NAV letter.
• Liquidity. There is no redemption queue. Terminating the mandate typically means revoking the manager’s authority, not waiting out a lock-up.
• Customization. Mandates can be tailored: exclude certain assets, cap leverage, set drawdown limits.

Cons:

• Custodian dependence. The assets sit at a third-party custodian chosen for (or by) the structure. That is far safer than commingling, but it still introduces a counterparty: a custodian can fail, freeze withdrawals, or be compromised. You have swapped fund risk for custodian risk.
• Higher minimums than funds’ pooled entry points. SMAs are operationally heavier per client, so managers typically require $250,000–$1 million+ before the economics work.
• Withdrawal authority varies. In some SMA setups the manager or the platform retains broader account permissions than clients realize. Read the mandate documents closely; they spell out what the manager can actually do.

An SMA solves commingling. It does not fully solve custody.

How is a non-custodial managed account different?

A non-custodial managed account takes the SMA logic one step further: instead of moving assets to a custodian associated with the manager, the assets stay in your own exchange account — one you opened, you verified, and you alone can withdraw from.

The mechanics rely on exchange sub-account architecture. On derivatives venues like Deribit or major spot exchanges like Binance, an account holder can create a sub-account and grant a third party restricted access to it: trading enabled, withdrawals disabled. The exchange’s own systems enforce those permissions, so nothing rests on a contract you would have to litigate. The manager can open and close positions — covered calls, cash-secured puts, hedged grid orders — but a withdrawal request from the manager is technically impossible.

Pros:

• You keep custody. The design itself removes the single largest risk in crypto asset management: handing your coins to someone else.
• Full, live transparency. It’s your account. You can log in and see every position, every trade, every balance, at any moment.
• Instant exit. Revoke the sub-account access or API keys and the mandate is over — no redemption notice, no waiting for a NAV date.
• Clean incentive structure. Because the manager cannot touch principal, compensation is typically a performance fee on documented results, often with a hurdle, rather than a management fee collected on assets they hold.

Cons:

• Operational setup falls on you. You open the exchange account, pass KYC, create the sub-account, fund it, and manage your own security (keys, 2FA, whitelisted withdrawal addresses). A fund’s paperwork is heavier; a non-custodial account’s operations are heavier.
• Per-exchange limits. The strategy universe is bounded by what your exchange supports. Sophisticated options strategies live largely on Deribit; a venue without the right instruments can’t run them. Multi-venue diversification means multiple accounts.
• Exchange risk remains. Non-custodial management removes the manager as a counterparty, but the exchange itself still holds the assets. Cold-storage purists will note, correctly, that coins on any exchange are not coins in your own wallet. Mitigations exist (keeping only working capital on-venue, choosing regulated exchanges), but the risk does not go to zero.
• No pooled diversification. A fund can offer a 40-position portfolio and early-stage deal access; your account runs a single mandate.

Packed Capital chose this structure on purpose: it is a managed account rather than a fund. The firm’s rules-based options-income strategies, refined since 2018, trade inside the client’s own exchange account and target 20–25% a year.

Crypto fund vs managed account: how do the three compare?

The crypto fund vs managed account decision compresses into seven dimensions:

	Pooled fund	SMA	Non-custodial managed account
Custody	Fund/GP via its custodian	Your name, at a third-party custodian	Your own exchange account
Counterparty risk	GP + fund custodian + fund’s venues	Custodian (+ manager’s permissions)	Exchange only; manager can’t withdraw
Liquidity	Redemption windows (monthly/quarterly), lock-ups, notice periods	Terminate mandate; settlement via custodian	Immediate — revoke access anytime
Minimums	Varies; often $100k+ per the offering memorandum	Typically $250k–$1M+	Typically $100k+ (strategy-dependent)
Fees	Management + performance fee (hurdle, high-water mark)	Management fee, sometimes performance	Typically performance-only, often with hurdle
Transparency	Monthly NAV statements, audited annually	Position-level, often daily	Total; it’s your account, live
Who it suits	Investors wanting diversification, venture access, zero operations	HNWIs wanting segregation with traditional custody	Holders who prioritize custody control and verifiability

One regulatory note that cuts across all three: in the EU, the Markets in Crypto-Assets Regulation (MiCA) became fully applicable to crypto-asset service providers on 30 December 2024, requiring authorization and prudential standards for custody and portfolio management services. Whichever structure you choose, ask where each entity in the chain — manager, custodian, exchange — sits relative to MiCA or its equivalent in your jurisdiction.

Which structure suits family offices vs individuals?

Which structure is best depends on the holder. A workable decision framework:

Choose a pooled fund if:

• You want exposure to venture-style or multi-strategy portfolios you cannot replicate in one account.
• You value zero operational involvement over custody control.
• You can tolerate lock-ups, redemption notice periods, and NAV-based reporting.

Choose a crypto SMA if:

• You want segregated assets and position-level reporting, and you trust (and have diligenced) a qualified custodian.
• Your allocation clears the higher minimums.
• You want mandate customization — asset exclusions, leverage caps, drawdown rules.

Choose a non-custodial managed account if:

• Custody control is your first filter — you will not wire principal to any third party, full stop.
• You already hold assets on (or are comfortable opening) a major exchange such as Deribit or Binance.
• You want to verify performance yourself, live, rather than trust statements.
• You accept the setup work and the single-venue constraint as the price of keeping the keys.

For family offices and treasuries, the calculus usually tightens around governance: an investment committee must explain to principals what happens in the worst case. The cleanest worst-case answer crypto currently offers is that the assets never left the firm’s own account and the manager had no ability to withdraw them. That is why the non-custodial model, sometimes alongside a small fund allocation for diversification, increasingly anchors the core position. For individuals in the $100k–$1M range, the choice often reduces to SMA-style custody trust versus non-custodial verifiability; below fund and SMA minimums, non-custodial managed accounts are frequently the only institutional-grade option short of buying a retail structured product.

FAQ

Is a crypto SMA safer than a crypto fund? Generally yes, on segregation: SMA assets are held in your name and are not commingled, so another investor’s redemption or the fund’s blow-up doesn’t touch you. But an SMA still depends on its custodian. A non-custodial managed account removes even that layer: assets stay in your own exchange account.

Can a non-custodial manager steal or withdraw my funds? No. Withdrawals are disabled at the exchange level: a restricted sub-account or trade-only API key permits placing and closing orders but not moving funds out. The residual risks are the exchange itself and poor mandate design (for example, excessive leverage).

What returns should I expect from a crypto managed account? Returns depend on the strategy far more than on the wrapper. Hedged options-income strategies typically target moderate, repeatable yield (Packed Capital, for instance, targets 20–25% annually), while directional funds swing far wider in both directions. Treat any “guaranteed” figure, in any structure, as a red flag.

What minimums apply to each structure? Crypto funds commonly start around $100k per their offering memorandum; SMAs usually require $250k–$1M+ because of per-client overhead; non-custodial managed accounts typically start near $100k, since the client’s own exchange account carries most of the operational load. Always confirm current terms directly — minimums move with market conditions.
