How Bitcoin-backed loans work in 2025
Oct 28•6 min read

A Bitcoin-backed loan lets you borrow cash or stablecoins without selling your Bitcoin.
You keep exposure to BTC’s future upside while unlocking liquidity for real-world goals — whether that’s buying a house, funding a business, or covering life’s bigger expenses.
It’s the modern equivalent of what wealthy investors have done for decades: borrowing against assets like stocks or real estate, which they believe will keep appreciating.
Why do some investors borrow instead of selling?
Selling Bitcoin can feel like selling your future. Once it’s gone, you’ve locked in gains and potentially a tax bill while losing out on any further appreciation.
Borrowing against it, on the other hand, means you can:
- Access cash without triggering a sale or taxable event.
- Keep your BTC working toward potential long-term growth.
- Manage liquidity during volatile markets.
That’s the logic driving a growing group of investors in 2025 — people who see their Bitcoin not as something to spend, but as something to leverage.
How does a Bitcoin-backed loan actually work?
You pledge Bitcoin as collateral.
Your BTC is locked (not sold) and used to back the loan.
You receive funds.
Depending on the platform, that can be in fiat or stablecoins, often within minutes.
You’re exposed to a price increase.
While locked, you still benefit if the Bitcoin price rises.
You repay flexibly.
Once you’ve paid back the loan and interest, your BTC is available once again.
Platforms like Nexo position this around key parameters:
- Loan-to-Value (LTV): The ratio of what you borrow vs. what your BTC is worth. Lower LTV means lower risk.
- Interest rates from 2.9%, depending on your Loyalty Tier and collateral ratio.
- No fixed repayment schedule, meaning you repay at your own pace, in crypto or stablecoins.
- Multi-asset collateral flexibility, letting you combine Bitcoin with other supported assets such as Ethereum or stablecoins to back your loan.
If your loan is in stablecoins, here’s how that works:
Many platforms, including Nexo, give you a choice: you can withdraw your Bitcoin-backed loan in either fiat or stablecoins — digital assets that are pegged 1:1 to major fiat currencies like USD, EUR, or GBP.
If you choose fiat, the process is seamless and fast. You can withdraw the funds straight to your bank account, with automatic, real-time conversions handled directly on the platform.
If you choose stablecoins, you have two clear paths depending on what you need:
1. You want to use the funds in the real world
If your goal is to pay for something tangible — a property deposit, a renovation, or a business funding — you can:
- Swap stablecoins for fiat directly on the platform or via an exchange.
- Then withdraw to your linked bank account.
Because stablecoins like USDC are pegged to the dollar, the conversion is straightforward — one USDC is designed to equal roughly one U.S. dollar. It’s a digital bridge between your Bitcoin holdings and your bank account.
2. You want to keep the funds in the crypto ecosystem
If your plan isn’t to spend right away, you can use your stablecoins within the platform to grow or diversify your portfolio:
- Swap into other cryptocurrencies you believe in (for example, converting USDC into ETH, BTC, or SOL).
- Reinvest strategically, as many users use their borrowed stablecoins to take new positions or to dollar-cost average into other assets.
This is what makes borrowing in stablecoins flexible: they move seamlessly between digital and traditional finance.
The real-world use case: buying a home with Bitcoin.
Imagine this: You own 5 BTC, each worth $100,000.
Instead of selling them to fund a property deposit, you use them as collateral for a Bitcoin-backed loan. The property becomes yours, while your Bitcoin remains in play, ready to benefit if prices rise.
That’s not theoretical. In 2025, a growing number of people are doing exactly this. Some even finance entire home purchases using Bitcoin collateral — a concept once seen as outlandish and now becoming increasingly common.
It’s a sentiment many long-term holders share.
How much can you actually borrow?
When you borrow against Bitcoin, the loan amount you can unlock depends on something called your Loan-to-Value ratio, or LTV.
LTV measures the size of your loan compared to the value of your Bitcoin collateral. It’s shown as a percentage.
For example, if you use $200,000 worth of BTC to borrow $100,000, your LTV is 50%. That means your loan is worth half the value of your Bitcoin holdings.
For Bitcoin, most platforms, including Nexo, set the highest LTV at around 50%. This buffer exists because Bitcoin’s price can move fast. By lending you only up to half of your asset’s value, the platform helps protect both sides:
- You’re less likely to face a margin call if BTC dips.
- The lender can manage risk without selling your collateral too soon.
Lowering your LTV (say, to 20–30%) gives you even more protection against volatility and often qualifies you for better interest rates.
What happens if your LTV rises?
If the price of Bitcoin drops, your LTV rises automatically because your collateral is worth less. If it crosses a certain threshold (often around 70–83% depending on the platform), you’ll receive a margin call, which is a reminder to:
- Add more collateral (more BTC or other assets), or
- Repay part of the loan to restore balance.
If no action is taken, part of your Bitcoin may be automatically sold to bring your LTV back to a safer zone.
When it works and when it doesn’t.
Bitcoin loans work best when:
- You have a strong long-term conviction in BTC.
- You only borrow what you can comfortably repay.
- You monitor your LTV during volatility.
It can go wrong if:
- The Bitcoin price drops sharply, and your collateral is automatically used to repay the loan.
- You don’t act on margin call notifications.
- You treat a crypto loan like “free money.”
Why are people turning to crypto loans?
People use Bitcoin-backed loans for different reasons:
- Real estate purchases to unlock deposits or refinance traditional mortgages.
- Business growth to fund ventures without selling long-term holdings.
- Tax management to access liquidity without triggering taxable events.
- Diversification to use BTC value while staying invested.
In essence, it’s about turning digital wealth into usable liquidity.
What makes it different from a traditional loan
A Bitcoin-backed loan isn’t the same as a bank loan. You’re borrowing against your digital assets, not your credit history or income.
Traditional loans:
- Based on income, credit score
- Takes weeks to process
- Monthly repayment schedule
Bitcoin-backed loan
- Based on the value of your BTC
- Same-day approval
- Flexible repayment at your pace
- Bitcoin as collateral
Important: If the BTC price drops too far, the lender may sell part of your Bitcoin to restore balance, but your property or other assets remain untouched.
FAQs
1. How can I get a Bitcoin loan?
By using your BTC as collateral on a trusted platform. You receive cash or stablecoins, while your BTC stays locked until you repay.
2. What happens if Bitcoin drops?
If your Loan-to-Value ratio rises significantly, you may need to add collateral or repay part of the loan to avoid liquidation.
3. Do I pay taxes when I borrow against Bitcoin?
Typically, borrowing doesn’t trigger capital gains tax — since you’re not selling your BTC. However, always check local regulations and consult with professionals in your jurisdiction.
4. Is it safe to borrow against Bitcoin?
It is important to borrow responsibly with reputable providers and low LTV ratios. Risk increases with volatility or over-leverage.
