How to actually evaluate a Bitcoin-backed lender

A Bitcoin-backed loan is a loan secured by Bitcoin as collateral. You transfer your Bitcoin to the lender (or a custodian acting on the lender’s behalf), borrow dollars against it, and pay the lender interest until you repay the principal and reclaim the Bitcoin.

The mechanics are similar to a securities-backed line of credit at a traditional brokerage, but with one structural difference: Bitcoin’s volatility is much higher than the stocks and bonds that typically back margin loans. That difference is what drives almost every risk question that follows.

For Bitcoin holders, the appeal is straightforward. You can access liquidity without selling, which means no capital gains tax event and no loss of upside if Bitcoin appreciates during the loan term. For a long-term holder, this is often a better outcome than liquidating, even after accounting for interest costs.

The risks come from what happens between today and when you repay.

Bitcoin-backed loans are not for everyone. Three conditions usually need to be true before borrowing makes sense.

You have a clear repayment path. The loan is an instrument, not a strategy. If you don’t know when and how you’ll repay, the loan can become a forced sale at the worst possible time. Repayment can come from income, from another asset, or from a planned future Bitcoin sale, but it has to be planned.

Your time horizon for the Bitcoin is longer than the loan term. If you would have sold the Bitcoin anyway within the loan period, borrowing against it adds cost and risk without preserving the position. The strategy works when you genuinely intend to hold the underlying Bitcoin for years after the loan is repaid.

You can afford the worst case. The worst case for a Bitcoin-backed loan is partial or full liquidation of your collateral during a Bitcoin drawdown. If that outcome would materially damage your financial situation beyond losing the loan, the loan is too large.

If those three conditions don’t hold, the loan is likely the wrong tool. The framework below assumes you’ve already decided this is the right approach for your situation and you’re now choosing a lender.

Rehypothecation is the question that matters most

Rehypothecation means the lender re-uses your collateral for its own purposes, typically by lending it out to other counterparties or using it to support its own balance sheet positions. The collateral leaves your segregated account and enters the lender’s broader operations.

This is the single most important question to ask any Bitcoin-backed lender. If a lender rehypothecates your Bitcoin and then becomes insolvent, you are an unsecured creditor in their bankruptcy. The Bitcoin you posted as collateral is no longer separately yours. It is part of the lender’s general estate, available to all creditors.

When Celsius, BlockFi, and Voyager collapsed in 2022, this is what their customers learned. Despite marketing language suggesting customer funds were safely held, the operational reality was rehypothecation. Customers became unsecured creditors and recovered cents on the dollar, often years later.

Lenders that do not rehypothecate post your collateral to a segregated account at a qualified custodian, or use a collaborative custody arrangement where you retain partial control. These structures survive lender bankruptcy in a way that rehypothecated arrangements do not.

Ask the question directly. If a lender’s marketing language is ambiguous, that ambiguity is the answer.

Custody arrangement determines what you actually own

Custody is not a single category. Bitcoin-backed lenders use at least four meaningfully different custody arrangements, each with different implications for your legal claim to the collateral.

Qualified custodian, segregated. Your Bitcoin is held at a regulated custodian (such as BitGo, Coinbase Custody, or Anchorage) in a wallet or sub-account that is legally identified as yours. This is the strongest arrangement for borrower protection.

Lender balance sheet. Your Bitcoin sits on the lender’s own balance sheet. The lender may claim to segregate it operationally, but legally it is the lender’s asset. This is the weakest arrangement and the one most prone to failure during stress.

Collaborative multisig. Used by lenders like Unchained, where collateral is held in a multi-signature arrangement requiring keys from you, the lender, and sometimes a third party. The Bitcoin cannot be moved without your participation, which provides strong protection against unilateral action by the lender.

Exchange custody. Used by lenders integrated with exchanges (such as Bitfinex Borrow). The collateral sits within the exchange’s broader custody system, which mixes characteristics of qualified custody and balance sheet exposure depending on the exchange’s actual arrangement.

The Loan Calculator’s “Custody” column on each lender row identifies which arrangement the lender uses. The differences are not academic. They determine what happens to your Bitcoin if the lender fails.

Liquidation cascade design tells you how much margin for error you have

Every Bitcoin-backed loan has a loan-to-value (LTV) ratio: the dollar value of your loan divided by the dollar value of your Bitcoin collateral. As Bitcoin’s price moves, your LTV moves with it. Above a certain threshold, the lender liquidates collateral to bring the LTV back down.

The structural question is what happens before that liquidation. Well-designed cascades give the borrower meaningful warning and time to respond:

• A first warning at moderate LTV (typically 65-75%)
• A formal margin call at higher LTV (typically 75-85%), with a grace period of 24 to 72 hours
• A liquidation threshold at high LTV (typically 80-90%) only after the grace period expires

Poorly designed cascades collapse these stages. Algorithmic liquidation at a single threshold with no warning, no grace period, and no opportunity to add collateral or pay down the loan means a single bad Bitcoin candle can liquidate your entire position before you’ve had breakfast.

This matters more than the headline LTV ratio. A lender offering 70% LTV with a 48-hour grace period gives you more protection than a lender offering 50% LTV with instant liquidation, despite the lower loan amount being safer-sounding.

Some lenders publish their full liquidation cascade. Others do not. A lender that does not publish its cascade is asking you to trust the operational details of the most important moment in the loan. We rate that as a credibility issue.

Jurisdiction and regulation set the floor on what protections exist

Where the lender is based, and which regulatory regime governs it, determines what legal recourse you actually have.

US-regulated lenders operate under federal and state oversight: anti-money-laundering rules, capital requirements, custody regulations, and (depending on structure) state-level money transmitter or trust company licenses. This regulatory structure does not prevent failures, but it creates documentation requirements, periodic examinations, and dispute mechanisms that offshore lenders typically lack.

Offshore lenders operate under whatever rules their jurisdiction imposes, which range from substantive (Switzerland, Singapore, UK in many areas) to functionally nonexistent. The 2022 collapses included multiple offshore-domiciled lenders where customer recovery efforts were complicated by jurisdictional barriers in addition to insolvency itself.

Regulation is not a guarantee of safety. Several US-regulated lenders failed in 2022. But regulation creates a floor on transparency and a paper trail. For most readers, that floor is worth the slightly higher rates US-regulated lenders typically charge.

Collateral types accepted signal how the lender thinks about risk

Some Bitcoin-backed lenders accept only Bitcoin. Others accept Bitcoin alongside Ethereum, stablecoins, or a broader set of crypto assets. A small number accept Bitcoin alongside traditional assets like equities.

This matters for two reasons.

First, mixed-collateral lenders have correlated downside exposure. When crypto markets stress, all crypto collateral types tend to fall together, which means the lender’s overall collateral pool deteriorates faster than the Bitcoin alone would suggest. A Bitcoin-only lender’s risk profile during stress is purely Bitcoin’s profile. A mixed-collateral lender’s profile is a blend that may be harder to model.

Second, the choice of accepted collateral signals how the lender views risk. Bitcoin-only lenders typically treat Bitcoin as a fundamentally different asset class with different risk properties. Mixed-collateral lenders typically treat all digital assets as fungible from a risk-management perspective. Neither view is automatically correct, but they produce different operational decisions, and the lender’s view should match your own.

Track record through stress events is the most useful single data point

Most Bitcoin-backed lenders have been in business through at least one major Bitcoin drawdown and the 2022 lender collapse cycle. How they performed during those events is the single most useful data point you have.

Look for: lenders that operated continuously through 2022 without halting withdrawals, freezing accounts, or restructuring debt. Lenders that disclosed their custody and rehypothecation arrangements clearly during the stress period. Lenders whose communications during stress were factual rather than reassuring.

Avoid: lenders that paused operations and resumed under new ownership or terms. Lenders whose communications during stress contradicted their later regulatory disclosures. Lenders that had to be acquired or absorbed to survive.

A lender’s marketing in calm markets is a marketing claim. A lender’s behavior during a stress event is a structural revelation. Weight the second far more heavily.

Bitcoin-backed lending is a legitimate tool. Used by readers with clear repayment paths, against a Bitcoin position they genuinely intend to hold long-term, with a lender whose structural risk they have actually evaluated, it can preserve significant value compared to selling.

The hard part is the evaluation itself. The six dimensions above are not optional research. They are the minimum framework for understanding what you are actually agreeing to when you accept a loan term sheet.

Use the Loan Calculator to compare specific lenders across these dimensions. The calculator surfaces published data on cascade design, custody, and rate structure for each lender we cover. What it cannot do is replace the underlying judgment, which is yours.

A discipline closer:

If you cannot answer the six questions in this guide about your prospective lender (rehypothecation policy, custody arrangement, full liquidation cascade, jurisdiction, accepted collateral, and track record through 2022), do not take the loan yet. The cost of waiting until you understand the structural answer is small. The cost of taking a loan you don’t fully understand can be your entire collateral position.

Most lenders that survive long-term answer these questions clearly because clear answers are part of how they earn trust. A lender that resists clear answers is telling you something important about their internal posture toward customer risk. Listen to it.
