Picture a Tuesday night. The kitchen needs a remodel, or a tuition bill landed, and you’re staring at a bitcoin balance you bought years ago and swore you’d never touch. Selling feels like betraying your past self. Not selling feels like leaving your family’s options on the table.
Borrowing against bitcoin is the middle path. You pledge your BTC as collateral, receive dollars (or a stablecoin), and get your bitcoin back when you repay. It can work well. It can also go badly if you borrow too much, pick the wrong custody setup, or ignore the tax rules. This guide walks through how it works, how to size a loan so a bad month doesn’t wreck you, and what to check first.

- A bitcoin-backed loan lets you get cash without selling. In the US, borrowing itself is generally not a taxable event. Separately, a forced liquidation is generally treated as a sale, which can trigger capital gains tax.
- Your loan-to-value ratio (LTV) is the single biggest safety lever. Conservative borrowers stay far below the lender’s maximum.
- Check whether the lender can reuse your collateral (rehypothecation) before you send anything.
- A loan is a liquidity tool, not a yield machine. Anything you do with the proceeds carries its own risk.
- Talk to a CPA before you borrow, especially about interest deductibility.

How a bitcoin-backed loan works
A bitcoin-backed loan is a secured loan. You use your bitcoin as collateral to borrow dollars rather than selling it. The structure is the same as a home equity loan: pledge an asset, borrow against it, and get the collateral back once the loan is repaid.
The moving parts are simple:
- Collateral: the BTC you pledge.
- Principal: the dollars you borrow.
- LTV: principal divided by the current value of the collateral. Borrow $20,000 against $50,000 of BTC and your LTV is 40%.
- Interest: what you pay for the loan, which varies by lender and market.
- Liquidation threshold: the LTV at which the lender can sell some or all of your collateral to protect itself.
Think of LTV like the water line on a boat. The more cargo you load, the closer the waterline sits to the rail, and the smaller the wave that sinks you. Bitcoin makes waves for a living.
For a deeper walkthrough of mechanics across BTC and ETH, we cover it in how crypto-backed loans work.
Why people borrow instead of sell
Common reasons are practical:
- They believe in the long-term holding. Selling means you might not buy back at a price you like.
- Taxes. Selling can create a capital gains bill. A loan generally doesn’t, though there are exceptions covered below.
- Timing. Cash for a down payment, a business need or a gap between jobs, without a forced decision about the whole stack.
Notice what’s missing from that list: “to make money.” A loan on its own produces no return. It’s better to treat a loan as a liquidity and risk tool rather than a yield strategy: it gives you access to cash, and anything you do with that cash carries its own risk.
Choosing your LTV: where most people get hurt
Lenders will often let you borrow far more than is wise. The maximum is the lender’s number. Your number should be lower.
One commonly cited conservative starting point is an initial LTV of roughly 25 to 40%, though that’s a third-party guideline, not a rule. Whatever number you choose, a low starting LTV is your main insurance, more than your reaction time. That matters because margin calls tend to arrive when prices are already weak, so a liquidation can lock in your loss at close to the worst moment and leave you without the asset during the recovery.
A worked example
Say you hold 1 BTC and, for round numbers, it’s worth $100,000. These are illustrative numbers, not a forecast or a quote from any lender.
| Borrowed | Starting LTV | BTC price drop that pushes LTV to 80% |
|---|---|---|
| $20,000 | 20% | 75% drop |
| $30,000 | 30% | 62.5% drop |
| $50,000 | 50% | 37.5% drop |
| $70,000 | 70% | 12.5% drop |
The math: LTV equals loan divided by collateral value, so the collateral can fall until the loan equals 80% of its value. At a 70% start, a 12.5% dip gets you there, and bitcoin can move that much in a short period. The 80% figure is only an example threshold; your lender’s actual trigger may differ, so read the agreement. This also ignores accrued interest, which slowly pushes LTV up over time, so your real cushion is a little smaller.
A useful habit: pick a starting LTV, then ask what price drop you could sit through without touching anything. If the answer makes your stomach drop, borrow less. Our guide to stress-testing your LTV walks through this step by step, and the one on crypto loan liquidation covers what actually happens when the line is crossed.
The custody question nobody asks
When you pledge bitcoin, where does it go? This is the part that surprises people.
Seeing your collateral on-chain doesn’t tell you whether it’s segregated or rehypothecated. With rehypothecation, the lender can reuse your collateral for its own activities. If that lender fails, you can end up as an unsecured creditor in a bankruptcy rather than the owner of your coins. So the practical rule is to read the custodial agreement and look specifically for a no-rehypothecation clause.
Before you commit, get answers to these in writing where you can:
- Is my collateral held separately from the lender’s own funds?
- Can it be lent out, pledged or reused?
- What happens to it if the company enters bankruptcy?
- Who holds the keys, and under what legal structure?
Lenders generally fall into three types: centralized companies that hold your collateral, exchange-based loan products, and on-chain protocols where smart contracts hold it. Each has a different failure mode. A company can fail or freeze withdrawals. A smart contract can have a bug. None is risk-free. We go deeper in our piece on crypto collateral management.
Taxes: mostly friendly, with a sharp edge
This section is general information for US readers, not tax advice. Rules differ by country and by the exact terms of your loan.
The IRS treats virtual currency as property, so general property rules apply. In the US, borrowing against bitcoin is generally not treated as a sale, and loan proceeds generally aren’t treated as income. Bloomberg Law’s analysis, an opinion column written by an attorney, argues it can be an attractive way to raise cash for someone who has held less than a year and would otherwise face short-term gains.
Now the sharp edge. A forced liquidation counts as a sale of property. If your collateral is liquidated in a crash, you may owe capital gains tax on that sale, at a moment when your portfolio is already down. And interest deductibility is not a given: it may depend on whether the interest qualifies as investment interest expense, which has limits tied to net investment income. Interest on a loan used for personal spending, such as a renovation or tuition, is generally not deductible at all.
If you’re in Canada, it’s murkier. The CRA’s non-exhaustive list of dispositions includes transfers of ownership as possible dispositions, such as gifts and donations, but it doesn’t directly address pledging crypto as loan collateral. A Canadian tax lawyer has written about uncertainty around transferring crypto as part of lending transactions. Whether your arrangement transfers beneficial ownership matters, so get advice specific to your loan agreement.
Who to see: a CPA or tax attorney who has handled digital assets, before you borrow, not after. Bring the lender’s agreement. For more on the US side, see our guides on crypto loans and capital gains tax and accessing cash without selling BTC or ETH.
What to do with the money
This is where the “daily income” idea comes in, and where it pays to be careful.
Some borrowers use proceeds for real life: a renovation, a down payment, a tax bill, a business cash gap. That’s the simplest and most defensible use. The loan has a purpose, and you know the cost.
Others deploy the proceeds into strategies meant to earn more than the loan costs. That is borrowing to invest, and it adds a second layer of risk on top of the first, because now you can lose on the strategy and still owe the loan. Using these loans to aggressively leverage a position can turn a manageable correction into a forced liquidation.
And please, be skeptical of promises of steady daily returns. One trading blog claims 80 to 95% of day traders lose money. That exact figure is hard to verify, but the broader point holds: most day traders lose money, and steady daily returns are rare. If a pitch for your borrowed dollars sounds like a guarantee, walk away. That includes ours: we don’t promise returns, and anything we teach comes with the question “what could go wrong?” attached.
If you do plan to put proceeds to work, size it small relative to your total holdings. Our guide on sizing income positions and the 15-minute pre-deposit check for liquidity pools are good places to start.
A pre-borrow checklist
Run through this before you send a single satoshi:
- Decide the purpose. Write down what the dollars are for and when you’ll repay.
- Set your LTV. Start well below the lender’s maximum, and write down the price at which you’d add collateral or repay.
- Read the custody terms. Look for segregation and a no-rehypothecation clause.
- Understand the liquidation rules. What’s the trigger? How much gets sold? Is there a grace period or a fee?
- Plan the top-up. Keep spare cash or extra collateral ready, in an account you can reach on a bad day. Don’t plan on being able to react quickly; plan on being cushioned.
- Talk to your CPA. Ask specifically about liquidation and interest deductibility.
- Track the position. Set alerts well before the threshold. A portfolio tracking setup helps.
- Pick the collateral deliberately. If you hold both BTC and ETH, see how to choose a collateral asset.
- Spread your risk. Don’t put everything with one counterparty. See cross-protocol diversification.
It’s not glamorous. It’s also the stuff that separates a boring, successful loan from a story you tell at dinner with a wince. For the broader frame, our crypto risk management guide pulls it together.
Where we fit
We’re OverseasDeFi. We teach long-term Bitcoin and Ethereum holders how borrowing against crypto works, how to size and monitor it, and how to think about what to do with the proceeds, with risk awareness first. We provide education, tools and coaching. We don’t take custody of your funds or manage investments for you, and you make your own decisions.
There are two ways in. Community and the Accelerator offer different levels of support, from portfolio tools and portfolio-aware AI coaching to live human guidance. Our tools can help you check your health factor and run stress tests on adverse prices, but they can’t prevent a liquidation or make decisions for you. We also teach wallet security first, before any income strategy. If you’d like to see the bigger picture first, start with our five-step guide to daily crypto income.
What to do this week
You don’t need to borrow anything yet. Do this instead: open a spreadsheet, enter your BTC amount, and test three loan sizes against a 30%, 50% and 70% price drop. See where each one lands. Then pick one question from the custody list and find the answer for a lender you’re considering. If you can’t get a clear answer, that’s your answer.
And if you’d like company while you do it, we’re around. No pressure, no countdown timers. Just a place to ask the questions you’d feel silly asking elsewhere.
FAQ
Is borrowing against bitcoin taxable?
In the US, borrowing is generally not treated as a sale, and loan proceeds generally aren’t treated as income. For one perspective, see Bloomberg Law’s analysis, an attorney’s opinion column. A liquidation, however, is treated as a sale and can create a capital gains bill. Confirm your situation with a CPA, particularly regarding interest deductions.
What LTV should I use?
There’s no universal number. One commonly cited guideline is a conservative starting LTV, often 25 to 40%, well below the platform’s limit, but your own number depends on how large a drop you can sit through. Test your loan against a large price drop before you accept it. If a 50% decline would force a liquidation and that scares you, go lower.
What happens if bitcoin’s price falls?
As the price drops, your LTV rises. The lender will typically ask you to add collateral or repay part of the loan, and if you don’t, it can sell your collateral. Because that selling can happen near market lows, a low starting LTV protects you better than a fast reaction.
Can I use the loan to earn daily income?
You can, but that means borrowing to invest, which adds risk on top of the loan. A loan doesn’t produce a return by itself, and no strategy should be treated as guaranteed. Start small, understand each step, and size positions so a bad outcome doesn’t threaten your core holdings.
