Abstract illustration of a crypto portfolio

How much of a BTC or ETH position could you put into an income strategy while protecting money your household needs? Long-term holdings used in DeFi can still be delayed or lost. Start with money you can afford to lose permanently—not funds you could only tolerate locking for a while, and not the advertised yield. Keeping 60% of your crypto readily accessible might be one person’s preference, but it is not a rule that fits every household or strategy.

In brief: Set aside near-term spending money first. Decide what loss and delay you could withstand. Then compare each method’s income source, costs and exit route. A portfolio allocation is not the same thing as a loan’s loan-to-value (LTV) ratio, and neither an alert nor a cash reserve eliminates protocol risk.

Build a sizing framework around your needs

Begin outside the crypto portfolio. List upcoming expenses, debt payments and money your household might need on short notice. Decide what cash reserve fits those obligations before treating any crypto as available for a DeFi position. There is no number of months that makes a reserve sufficient for everyone.

Next, define “accessible” precisely. BTC or ETH in a wallet that you can transfer without closing a loan, waiting for a validator exit or withdrawing from a pool is more readily accessible than collateral or staked assets. Access still depends on your wallet, the network and any intermediary you use. An asset you can sell quickly may also have fallen sharply in value by the time you need it. The SEC’s Office of Investor Education and Assistance issued the Investor Bulletin, which raises questions about intermediaries, including whether they may pool or use customer assets.

Choose a maximum deployment loss that would not disrupt your household or force the sale of holdings you intended to keep. Consider the amount as a share of both your crypto holdings and your broader investable assets; a modest-looking crypto percentage may still represent a substantial household loss. If you choose to keep 60% of your crypto outside income strategies, specify what counts toward that figure and test whether putting the other 40% at risk is actually affordable.

Finally, test more than one adverse scenario: a steep collateral-price decline, a simultaneous fall in both assets in a pair, lower fee income, higher borrowing costs, costly transactions and a delayed exit. Alfred Lehar and Christine A. Parlour studied lending-market liquidations and found that DeFi’s automated liquidation processes can magnify price declines in the markets they examined. Their findings are a reason to model difficult exits, not a formula for a universal buffer.

Compare the method before choosing an allocation

Borrowing against crypto

A loan may let a holder retain crypto exposure while deploying borrowed funds elsewhere. Any income from that deployment must be weighed against interest, fees and the risk of losing collateral. Borrowing does not make a liquidity pool’s impermanent-loss mechanics go away.

Two percentages matter here. Portfolio allocation describes how much of your holdings you commit to the strategy. LTV is the outstanding loan divided by the current value of its collateral. As a hypothetical illustration, a $5,000 loan against $20,000 of collateral starts at 25% LTV. If the collateral’s value falls to $12,000 while the loan balance stays at $5,000, LTV rises to about 41.7%, before interest and fees. That calculation does not identify a safe LTV: liquidation rules depend on the assets and protocol.

On a protocol such as Aave, borrowing capacity and the liquidation threshold are distinct; a position can become eligible for liquidation when its health factor falls below one. Check the rules of the position you actually use. The Aave FAQ explains its health-factor measure. Alfred Lehar and Christine A. Parlour’s BIS working paper on DeFi systemic fragility examines liquidations and price feedback on Compound and Aave; it does not establish an appropriate LTV for your position. Our guide to crypto loan liquidation covers the mechanics in more detail.

Solo staking and liquid staking tokens

ETH staking rewards arise from participating in network validation. Solo staking also carries validator operating responsibilities. For a validator, exit queues and slashing risk are separate considerations: a full exit may face a variable queue, while slashing can penalize certain validator behavior. The withdrawal guidance is useful for understanding exit timing; it is not a complete guide to validator penalties. For orientation on validator withdrawals, see the Ethereum.org withdrawals guide.

A liquid staking token (LST) is different from a solo-staked validator balance. An LST holder may be able to sell the token on a secondary market rather than wait for redemption, but the sale price can differ from the token’s redemption value. Redemption terms, liquidity, provider and smart-contract risks vary. Neither a market sale nor redemption promises access at a particular time or price. The Ethereum.org pooled-staking overview describes additional considerations when staking through a provider. For more context on validator exits, consult Ethereum withdrawals and validator exit mechanics — Launchpad (Ethereum.org); do not assume that an LST follows the same exit path.

Staking transactions can have different tax consequences depending on the jurisdiction and the details of the token and transaction. A 2023 announcement concerning Kraken’s staking-as-a-service program is one example among SEC press releases on crypto products. That settlement concerned a particular provider; it is not a general assessment of solo staking or every LST.

Liquidity pools

Liquidity providers may earn a share of trading fees, but their position value changes with the pool assets and prices. Impermanent loss describes a difference between the value of providing assets to a pool and holding those assets directly after their relative prices move; fees may or may not offset that difference. A concentrated position may earn more fees while prices trade within its chosen range, but it can stop earning fees when prices leave the range and can end up holding mostly one asset. A wide range is not automatically safe, and single-asset deposits do not all create the same economic exposure. Assess the specific pool, range and withdrawal terms rather than applying one sizing rule to every position.

If an intermediary holds assets for you, ask who controls them and whether they may be commingled or used as collateral. The SEC’s Office of Investor Education and Assistance issued the Investor Bulletin, which raises those questions. Separately, the SEC’s 2023 Kraken settlement announcement is one example among SEC press releases and statements on crypto products; it concerned that firm’s staking-as-a-service program and pooling of customer assets, not liquidity pools generally.

Three hypothetical 10% allocations

These examples show the arithmetic of allocating 10% of crypto holdings. They do not suggest that 10% is suitable, describe an observed portfolio or set a loan’s LTV.

  • $100,000 in BTC and ETH: 10% is $10,000. A complete loss of that position could still be material; compare it with household reserves and your tolerable loss.
  • $250,000 in BTC and ETH: 10% is $25,000. Splitting it between methods might reduce exposure to one position, but could introduce additional protocols, costs and risks.
  • $500,000 in BTC and ETH: 10% is $50,000. Track each position’s value, debt, fees, access conditions and planned exit—not just its stated yield.

An 8% position split between borrowing and a liquidity pool would likewise be a hypothetical choice, not a generally safer allocation. If borrowed funds finance the pool, model the loan and pool together: pool fees are uncertain, while borrowing costs and liquidation exposure remain.

Pre-deployment and monitoring checklist

  1. Protect household needs. Keep near-term obligations and your chosen cash reserve out of positions you may not be able to exit promptly.
  2. Map control and access. Identify who holds the assets, how withdrawal works, whether an intermediary may reuse or pool them, and what might happen if it fails. The SEC Office of Investor Education and Assistance’s Investor Bulletin offers questions to ask.
  3. Calculate the whole position. Record the amount deployed, any debt and LTV, borrowing interest, transaction costs, potential fees earned, and your comparison with simply holding the assets.
  4. Run adverse scenarios. Test price moves, changing rates, lost pool fees and delayed access. Alfred Lehar and Christine A. Parlour’s Systemic fragility in decentralised markets (BIS working paper), hosted by the BIS, provides context for why lending liquidations merit attention.
  5. Plan how you will respond. Set a review schedule and, where available, alerts that give you room to assess repayment, adding collateral or exiting. An alert can be delayed or missed; it cannot prevent an automated liquidation. Consider exit costs and jurisdiction-dependent taxes before you need to act.

Write down your assumptions and revisit them as balances and prices change. Seeing holdings, debt and risk together can help you ask better questions of a portfolio-aware AI coach, but a tool’s information may be incomplete or out of date. OverseasDeFi’s Daily Yield System frames the sequence as Hold → Borrow → Deploy → Earn; the borrowing step is a decision to evaluate, not a requirement. What matters is whether the potential net income justifies the combined risks for your circumstances.

FAQ

What percentage of my crypto should go into income strategies?

There is no universal percentage. Separate near-term needs first, define what remains readily accessible, and choose a possible loss you could withstand. Keeping 60% outside income strategies can be a personal starting preference, but it does not establish that deploying the remainder is affordable or safe.

How does LTV affect liquidation risk?

LTV is outstanding debt divided by current collateral value. It rises if collateral falls in value or debt grows. Each lending protocol sets its own rules for when a position can be liquidated. A buffer gives you more room for adverse moves, but rapid price changes or delayed action can still lead to liquidation.

Is staked ETH as accessible as ETH held in a wallet?

Not necessarily. A solo validator’s full exit can be delayed by a queue. An LST may be saleable sooner, but its market price can differ from redemption value, and access depends on market and provider conditions. Neither route is equivalent to simply holding transferable ETH.

What is impermanent loss in a liquidity pool?

It is the difference between the value of assets in a pool and the value of holding those assets directly after their relative prices move. Fees can offset some or all of that difference, but they are not guaranteed to do so. Borrowing to fund the position adds costs and collateral risk without changing the pool’s underlying mechanics.
