If you are holding Bitcoin and wondering how much can you borrow against bitcoin without selling a single satoshi, the honest answer is a formula, not a fixed number. Your borrowing capacity is collateral value multiplied by a maximum loan-to-value ratio, and that ceiling swings wildly depending on whether you borrow from a DeFi market like Aave or Morpho, a CeFi desk like Ledn or Nexo, or a hybrid product like Coinbase's onchain loans. This guide is about capacity: the maximum dollar figure a lender will hand you, the gap between what they allow and what you should actually draw, and how a moving BTC price quietly expands or shrinks your headroom. We will not rehash liquidation math or build an interest calculator here. We are answering one question precisely: what is the largest sensible loan you can take, and why the biggest number is almost never the right one.
Every Bitcoin-backed loan, whether it lives in a smart contract or on a lender's balance sheet, reduces to the same equation. Your maximum borrow equals collateral value multiplied by the maximum loan-to-value ratio. Collateral value is simply the current market price of your BTC times the number of coins you post. The loan-to-value ratio is the lever that decides how much of that value the lender is willing to lend against.
So if you deposit 1 BTC priced at $100,000 and the venue's maximum LTV is 50%, your ceiling is $50,000. Push the LTV to 70% and the ceiling jumps to $70,000. The collateral did not change; only the venue's risk appetite did. This is why two people with identical Bitcoin holdings can walk away with very different loan sizes. The question is never just "how much is my Bitcoin worth" but "what fraction of that value will this lender advance."
Rule of thumb for 2026: think of your Bitcoin's theoretical borrowing capacity as roughly half its market value at conservative CeFi venues, and up to two-thirds to three-quarters of value at the most aggressive DeFi markets. The difference is not generosity. It is a difference in who absorbs the risk when BTC drops.
Two variables drive the entire calculation, and both are moving targets. The Bitcoin price changes by the second, so your collateral value is never static. And the maximum LTV is set by each venue, adjusted by governance votes in DeFi or risk committees in CeFi, so the ceiling itself can be revised. When someone asks how much can I borrow against my bitcoin and expects a single tidy figure, they are missing that both inputs float. The number you see today is a snapshot, not a contract.
Here is the single idea that separates borrowers who keep their Bitcoin from borrowers who lose it in a liquidation. The maximum LTV is a theoretical ceiling. The safe LTV is what you should actually draw. They are not the same number, and treating them as the same is the most common and most expensive mistake new borrowers make.
Maximum LTV is the line the lender draws to define the largest loan they will originate. Liquidation, however, usually triggers at a slightly different threshold, and the moment your loan-to-value climbs into that danger zone, part or all of your collateral gets sold to repay the debt. The closer you originate to the max, the less room BTC has to fall before you are forced out of your position.
Consider a borrower who deposits 1 BTC at $100,000 and draws the full 70% allowed by a DeFi market: a $70,000 loan. If Bitcoin falls just over 18%, to around $81,500, the loan-to-value crosses into liquidation territory and the position unwinds. An 18% move in Bitcoin is a normal Tuesday, not a black swan. Now compare a borrower who draws 35% of the same collateral, a $35,000 loan. Bitcoin would need to fall roughly 58%, to about $42,000, before that position is in danger. Same coin, same venue, radically different survivability, simply because of how much of the available capacity was used.
Warning: The maximum LTV a platform advertises is the borrowing capacity you have access to, not the amount you should use. Borrowing at the ceiling means you have priced in a Bitcoin price that never falls. It always falls eventually.
This is why the rest of this article distinguishes between two numbers at every venue: the headline maximum (your true capacity) and a prudent draw (your sensible loan). For a deeper treatment of choosing the right ratio, our guide on optimizing your LTV ratio walks through how to size the buffer for your own risk tolerance, and the broader fundamentals live in understanding collateral and LTV.
Your borrowing capacity is dictated almost entirely by where you borrow. The same Bitcoin unlocks meaningfully different loan sizes across the three main venue categories, and understanding why helps you choose deliberately rather than landing wherever a single platform's marketing pointed you.
Decentralized protocols typically offer the highest theoretical capacity. On Bitcoin-backed lending markets built on Aave or Morpho, wrapped-BTC collateral often carries a maximum LTV in the 70% range and a liquidation threshold a few points higher. As of early 2026, WBTC on Aave V3 has carried a max LTV in the low-to-mid 70s with a liquidation threshold a couple points above that, while isolated wrapped Bitcoin markets on Morpho Blue for cbBTC against USDC have run with a liquidation loan-to-value (LLTV) as high as 86%. These are governance-set parameters and they change; always check the live figure before you size a loan.
A high LLTV does not mean you should borrow there. It means liquidation does not trigger until you are extremely close to the edge, which is dangerous if you draw near it. DeFi gives you the most rope; it also gives you the most rope to hang your position with. There is no hard maximum loan amount in DeFi, but there is a practical one: available liquidity in the pool. You can only borrow as much USDC as lenders have supplied to that market, and very large borrows push the utilization rate up, which raises your interest cost.
Centralized lenders are markedly more conservative on capacity. The industry standard for Bitcoin collateral at a CeFi desk is around a 50% maximum LTV. Ledn, for example, originates Bitcoin-backed loans at 50% LTV as of 2026; Nexo's credit line tops out near 50% for BTC as well. That means your $100,000 in Bitcoin unlocks roughly $50,000, not the $70,000 a DeFi market might allow.
The trade-off is service and predictability. CeFi desks handle custody, offer human support, and often provide a margin-call grace window before forced selling, which DeFi's automated liquidations do not. For the full comparison of these models, see comparing DeFi vs CeFi lending and the related glossary entries on decentralized finance and centralized finance.
Coinbase's onchain loan product is the notable hybrid. Behind a familiar exchange interface, your Bitcoin is converted 1:1 into Coinbase-wrapped Bitcoin (cbBTC) and supplied to a Morpho market on Base. The collateral ratio requirements are DeFi-grade (the market runs at an 86% liquidation LTV and a 133% minimum collateralization ratio), but Coinbase wraps a guided experience around it. As of 2026 the BTC-backed loan limit on Coinbase has been raised to as much as $5,000,000 USDC, a dramatic increase from the $100,000 cap at launch. Coinbase also added Ethereum-backed loans, so the venue is no longer Bitcoin-only.
| Venue Type | Typical Max LTV (BTC) | Hard Max Loan | Liquidation Style |
|---|---|---|---|
| DeFi (Aave V3, WBTC) | ~70-74% | Pool liquidity only | Automated, instant |
| DeFi (Morpho, cbBTC/USDC) | Up to ~86% LLTV | Pool liquidity only | Automated, instant |
| CeFi (Ledn) | ~50% | ~$1,000,000 | Margin call, then sale |
| CeFi (Nexo) | ~50% | Large, tier-dependent | Margin call, then sale |
| Hybrid (Coinbase / Morpho) | Up to ~86% LLTV | ~$5,000,000 USDC | Automated, instant |
Parameters as of early 2026 and subject to change by governance and risk committees. Always verify current terms with the venue before borrowing.
This is the table most people are actually looking for when they ask about max loan against btc. Below are the borrowable amounts in USDC across common Bitcoin holdings at three LTV levels: 25% (conservative), 50% (the CeFi standard and a reasonable middle ground), and 70% (aggressive, near the DeFi ceiling). The figures assume a Bitcoin reference price of $100,000 for clean math. Bitcoin does not actually sit at a round $100,000; it moves constantly, so treat these as proportions you can re-scale to whatever the live price happens to be.
| BTC Collateral | Value at $100k | Borrow at 25% LTV | Borrow at 50% LTV | Borrow at 70% LTV |
|---|---|---|---|---|
| 0.1 BTC | $10,000 | $2,500 | $5,000 | $7,000 |
| 0.5 BTC | $50,000 | $12,500 | $25,000 | $35,000 |
| 1 BTC | $100,000 | $25,000 | $50,000 | $70,000 |
| 5 BTC | $500,000 | $125,000 | $250,000 | $350,000 |
| 10 BTC | $1,000,000 | $250,000 | $500,000 | $700,000 |
To convert these to a live price, divide. At $100,000 per coin, 1 BTC at 50% LTV gives $50,000. If Bitcoin trades at $80,000 instead, that same 1 BTC at 50% gives $40,000. At $120,000 it gives $60,000. The LTV percentage is fixed by the venue; the dollar output floats with the market. This is the core reason your bitcoin loan amount is never a stable figure: the multiplier is constant, but the base it multiplies is not.
Tip: Read the 25% and 50% columns as your realistic planning range and the 70% column as a hazard line. A capacity table is a map of what is possible, not a recommendation. The right loan for most borrowers sits in the left half of this table, not the right.
Capacity is bounded on both ends. There is a smallest loan a venue will bother originating, and a largest loan it can or will fund. Both matter when you are sizing a real position.
The practical takeaway: if your loan is small, DeFi on a cheap chain or a CeFi desk with a low minimum is your friend. If your loan is very large, you are choosing between deep DeFi liquidity and a high-cap product like Coinbase, and you should watch how your borrow affects the pool rate. An aggregator is useful precisely because it surveys where the capacity and the rate actually are at the moment you want to borrow.
It is tempting to draw the full amount a lender allows. You posted the collateral; why leave capacity on the table? Because the maximum loan leaves zero buffer, and a zero-buffer loan is a position that liquidates on the first ordinary downswing. This is the most important behavioral point in the entire discussion of borrowing capacity bitcoin.
When you borrow at the ceiling, your loan-to-value starts at the maximum and can only go up from there, because LTV rises automatically whenever Bitcoin falls. You have no cushion. A 10% dip in BTC, which happens routinely, can push a maxed-out position straight into liquidation. And liquidation is not a neutral event: you lose collateral at a forced-sale moment, often near a local low, and you may pay a liquidation penalty on top. You can also crystallize a taxable disposition, since a forced sale of your Bitcoin is treated like any other sale.
Let's make it concrete. You deposit 1 BTC at $100,000 and a DeFi market lets you draw 70%, so you take $70,000. Your starting LTV is exactly 70%. The liquidation threshold sits a few points higher. Bitcoin only needs to slip to roughly $80,000-$82,000, a fall under 20%, before your collateral is sold out from under you. You did nothing wrong except use all your capacity. Compare drawing $40,000 against the same coin: your starting LTV is 40%, and Bitcoin would have to roughly halve before you are in danger. The buffer is the whole game.
The buffer rule: Your real safety margin is the distance between your starting LTV and the liquidation threshold. Borrowing the maximum sets that distance to nearly zero. Borrowing half the maximum doubles your room to be wrong about the market.
This is also why over-collateralization is a feature, not a bug. Posting far more value than you borrow is exactly what keeps your position alive through volatility. If you want to understand the failure mode in full, our sibling guide on what happens if you can't repay a crypto loan walks through default and liquidation step by step, and managing liquidation risk covers the defensive playbook.
Your borrowing capacity is not fixed because your collateral value is not fixed. When Bitcoin rises, the same coins are worth more, so the dollar amount you can borrow against them grows. When Bitcoin falls, your capacity shrinks, and if you already have a loan, your loan-to-value rises toward the danger zone without you doing anything at all.
Think of it as a tide. At a 50% max LTV, 1 BTC at $100,000 gives you $50,000 of capacity. If Bitcoin climbs to $130,000, that same 1 BTC now supports $65,000. You gained $15,000 of borrowing room purely from price appreciation, which is one reason some borrowers periodically top up a loan as their collateral appreciates rather than taking the maximum on day one. Conversely, if Bitcoin slides to $70,000, your 1 BTC supports only $35,000 of fresh borrowing, and any existing loan near the limit is now in trouble.
| BTC Price | 1 BTC Value | Capacity at 50% LTV | Capacity at 25% LTV |
|---|---|---|---|
| $70,000 | $70,000 | $35,000 | $17,500 |
| $100,000 | $100,000 | $50,000 | $25,000 |
| $130,000 | $130,000 | $65,000 | $32,500 |
This dynamic cuts both ways and explains a subtle strategy: borrowing a conservative amount today preserves the option to borrow more later if Bitcoin appreciates, without ever flirting with liquidation. It also explains why a position that felt safe at origination can drift into danger during a drawdown. Capacity is a function of price, and price is the one thing you do not control. For active management of collateral through volatility, see managing Bitcoin collateral during volatility and the habit of monitoring your crypto loan health.
Capacity tells you the ceiling. Your use case should tell you the actual number, and it is almost always well below the ceiling. The right loan size depends on how long you need the money, how predictable your repayment is, and how much volatility you can stomach without losing sleep or collateral.
A simple heuristic that serves most borrowers well: start at or below 35% LTV, treat 50% as a soft personal cap, and never originate above it unless you have a specific short-term reason and a plan to add collateral or repay quickly. That keeps your liquidation price a long way below the current market and converts your Bitcoin into a genuinely flexible line of credit rather than a tripwire.
Rule of thumb: Borrow what you need, sized to survive a 50% Bitcoin drawdown without liquidation. If your loan cannot survive Bitcoin halving in price, it is too big, regardless of what the platform's maximum allows.
Suppose you hold 2 BTC and Bitcoin is trading at $98,000 (a realistic 2026-style figure; the exact number will differ when you read this). Your collateral value is 2 x $98,000 = $196,000. You want to borrow USDC to fund a kitchen renovation and you want to keep your Bitcoin exposure intact.
Step one, find your capacity. At a CeFi desk with a 50% max LTV, your ceiling is $98,000. At a DeFi market with a 70% practical max LTV, your ceiling is $137,200. Those are your theoretical maximums.
Step two, ignore the ceiling and size to the renovation. Say the project costs $40,000. Drawing $40,000 against $196,000 of collateral puts your starting LTV at about 20.4%. That is deeply conservative, which is exactly what you want for a multi-month project where you do not control Bitcoin's price.
Step three, sanity-check the buffer. With a 20.4% starting LTV against a liquidation threshold in the high-70s or low-80s, Bitcoin would need to fall by roughly 70-75% before your position is at risk. Even a brutal bear market would not force a sale. You borrowed about 29% of your $137,200 DeFi capacity and about 41% of your $98,000 CeFi capacity, and in exchange you bought enormous resilience. This is what disciplined capacity usage looks like: the available ceiling was high, and you deliberately stayed nowhere near it. To compare how this loan would cost out across venues, our crypto loan calculator guide breaks down the interest side, and the best platforms to borrow USD against Bitcoin surveys where to actually originate.
None of this is financial or tax advice. Liquidation thresholds, LTV caps, and loan limits change; verify current terms with each venue and consult a professional for your situation.
One subtlety that quietly affects capacity: in DeFi, you almost never post native Bitcoin. You post a wrapped representation such as WBTC, cbBTC, or tBTC, and each carries its own risk parameters that feed into the collateral factor the protocol assigns. A wrapped asset the market trusts more may carry a higher max LTV; a newer or thinner-liquidity wrapper may carry a lower one. So your borrowing capacity can differ not just by venue but by which wrapped Bitcoin you bring. Our companion post on wrapped Bitcoin explained compares the three head to head for borrowing purposes.
The price oracle a protocol uses also matters for capacity, because your collateral is valued at the oracle's reported price, not necessarily the price on your favorite exchange. In fast markets these can diverge briefly. And isolated markets on Morpho carry parameters set by the curator who deployed them, so two cbBTC/USDC markets can have different LLTVs. The lesson: the headline LTV is a starting point, and the specific market's fine print is what actually governs your ceiling. If you are deciding between protocols, comparing Aave, Morpho, and CeFi lays out the structural differences.
A final framing that prevents a lot of regret: just because you can borrow a number does not mean you can service it. Capacity is about collateral and LTV. Affordability is about the interest rate and your ability to repay. A DeFi market might extend you $137,000 against 2 BTC, but if the variable interest rate spikes because utilization is high, a large balance becomes expensive fast. CeFi loans tend to carry higher but more stable headline rates, often in the high single digits to low teens for Bitcoin collateral as of 2026, while DeFi rates float with pool utilization.
So the complete capacity question has two halves. How much will a lender give you (this article), and how much can you afford to carry (a function of rate and repayment plan). Borrowing near your capacity ceiling stacks both risks at once: a thin liquidation buffer and a large, rate-sensitive balance. Borrowing conservatively defuses both. For the repayment side of the equation, our sibling guide on how to repay a crypto loan covers strategies to pay down and reclaim your collateral, and the decision of whether to borrow at all is the subject of should you sell or borrow against your Bitcoin.
Common Questions
At a Bitcoin price near $100,000, 1 BTC supports roughly $50,000 at a CeFi desk's typical 50% max LTV, and up to about $70,000 at a DeFi market's ~70% ceiling. But the prudent loan is far lower: drawing $25,000 to $35,000 against 1 BTC keeps a large liquidation buffer. The exact dollar figure scales with the live Bitcoin price, since capacity equals collateral value times max LTV.
