It’s your worst nightmare:

You’ve just borrowed $50k against your $BTC to get that new car you deserve after HODL-ing hard for years.

Then $BTC starts falling.

And falling some more.

You get an alert:

“Your loan has been LIQUIDATED.”

Bitcoin bounces right back – but your collateral was sold…all the way at the bottom.

You fall to your knees and scream:

WHYYYYYY????!!

….Just kidding.

You set up your Bitcoin loan with Ledn, and you’re sleeping like a baby.

Why?

Because you started with a healthy LTV, turned on Auto Top-Up, and knew exactly where your danger zones were before $BTC ever started dumping.

But don’t worry – you’re not alone.

We asked our readers across three different platforms, and more than 42% of you had the same crypto backed-loan fear:

Getting LIQUIDATED was top of mind.

But liquidation doesn’t have to come out of nowhere…

And with Ledn, there are a bunch of features that make getting a Bitcoin-backed loan MUCH less terrifying.

Side note: Ledn is pretty trustworthy too…it doesn’t lend out your collateral, keeps customer assets separate, confirms reserves every 6 months, and has funded $11.4B in loans with zero client losses.

How does Bitcoin loan liquidation work on Ledn?

Put simply, a lender needs to make sure your collateral stays worth more than what you owe, so the loan can always be repaid.

This all comes down to your LTV, or Loan-to-Value ratio.

If you borrow $50,000 against $100,000 of $BTC, that’s a 50% LTV.

If $BTC falls in value and your collateral is now worth $80,000, your loaned amount is still $50,000.

But now your LTV is 62.5%.

The loan didn’t get bigger – your collateral just got smaller (for now).

Ledn currently has three key thresholds:

• 70% LTV: first warning
• 75% LTV: another warning
• 80% LTV: automatic liquidation.

80% is Ledn’s safety line – if your LTV gets that high, it liquidates before another $BTC drop can put the loan underwater.

That liquidation involves Ledn selling just enough collateral to cover the outstanding loan balance plus any accrued interest.

Then, any remaining collateral goes right back into your Transaction Account.

But the real goal isn’t figuring out what happens at 80%.

It’s making sure you have enough of a buffer so that you never get there.

1. Start your Bitcoin loan with a sensible LTV

A lot of your liquidation risk is decided the moment you borrow against your Bitcoin.

The higher your starting LTV, the less $BTC has to fall before things get dangerous.

Ledn starts Dollar Loans at 50% LTV – you can’t borrow any more than that.

That gives you much more room than a more aggressive setup.

Other platforms let you go up to 70% or more – which feels generous…but really just gives you more risk.

I ran the numbers in a previous article to see if two different loan setups would’ve survived the 2022 FTX crash, when $BTC dropped 25% in a single week.

This is how it turned out:

• At 70% starting LTV with liquidation at 86%:

Your collateral only needs to fall about 18.6% before you get liquidated.

A 25% drop would’ve pushed the loan to roughly 93% LTV – for the loan, that’s game over.

• At 50% starting LTV with liquidation at 80%:

Collateral can fall about 37.5% before you get liquidated.

After the same 25% drop, the loan would’ve been sitting at roughly 67% LTV – still alive.

That’s ignoring interest, fees and pricing adjustments, but the difference is clear.

The conclusion?

A 50% starting LTV gives you roughly twice the breathing room.

2. Auto Top-Up adds another layer

The standard Bitcoin-backed loan advice during a $BTC price crash is:

“Just watch your LTV and add more collateral if you need to.”

Fine – unless you’re asleep, working, travelling, or simply don’t notice the move quickly enough.

That’s what Ledn's Auto Top-Up is designed for.

If your eligible loan reaches 70% LTV, Auto Top-Up automatically moves available $BTC from your Transaction Account into your loan collateral, to bring the LTV back toward 65%.

How much extra protection does that buy you?

Take our original example:

• $50,000 loan
• $100,000 starting collateral
• 50% starting LTV

With no extra collateral, you reach 80% LTV after roughly a 37.5% $BTC decline.

If you hold extra $BTC worth 10% of the original collateral and deploy it, your position can handle roughly a 43.2% drop.

With a 20% reserve, it rises to about 47.9%.

*Ignoring interest, fees and Ledn’s adjusted $BTC pricing.

3. Automatic protection for a crash, manual tools if you need more

Your starting LTV and Auto Top-Up are there to help absorb the sudden stuff.

But if the sell-off does turn into something deeper or more prolonged, you’ve still got manual options available:

a) Manually add more collateral

Auto Top-Up helps protect the loan automatically, but you can always add more collateral later if you decide you want an even bigger buffer.

Ledn lets you manually add $BTC from your Transaction Account or an external wallet.

You know the math:

More $BTC backing the same loan = lower LTV.

Just remember that $BTC sent from an external wallet needs blockchain confirmations before it actually affects your collateral balance.

So if you ever do need to step in manually, don’t leave it until you’re right below the liquidation limit.

b) Repay part of the loan

The other option is reducing the debt itself.

Ledn lets you make partial repayments without closing the loan.

Say your collateral has fallen to $70,000 and you still owe $50,000.

Your LTV is about 71%.

If you repay $10,000, then suddenly:

$40,000 / $70,000 = 57% LTV.

Same $BTC price, but a much healthier loan – and less debt.

How to set up an (almost) bulletproof loan

No $BTC-backed loan is literally bulletproof.

But here’s how you can make accidental liquidation much less likely.

1. Start with as much LTV breathing room as practical

Don’t borrow more just because the platform lets you.

The lower your starting LTV, the further $BTC has to fall before you reach the warning thresholds.

I like the fact that Ledn makes this a non-negotiable – every loan starts at a conservative 50% LTV, no matter what.

You can even drop your LTV further by manually topping up your loan once it’s open, if you want to be extra safe.

2. Use Auto Top-Up (Ledn Exclusive Feature)

Set it up before volatility comes, not halfway through a crash.

3. Keep a $BTC reserve behind it

A 10–20% reserve can pretty significantly boost the cushion your loan has against a drawdown, like in the simplified examples above.

4. Know your danger price levels

Before you borrow against Bitcoin, work out roughly what $BTC price would have to be to take your loan to:

• 60% LTV
• 70% LTV
• 75% LTV
• 80% LTV (the final liquidation zone).

That will turn liquidation from just a vague fear into real numbers you can track.

5. Have a contingency plan

Have a plan for what you’ll do at each of these levels.

Something as simple as:

• Below 60%: monitor.
• 60–70%: pay closer attention.
• 70%: Auto Top-Up activates, check the remaining reserve.
• 75%: consider manual collateral or partial repayment.
• Approaching 80%: act before automatic liquidation.

The exact plan is up to you – the important part is making it before $BTC is dumping.

Don’t try to predict Bitcoin

If you borrow against Bitcoin, you don’t need to know if $BTC is about to drop.

You need to know what your loan will do if it does.

• Know your starting LTV.
• Know your warning thresholds.
• Know how much $BTC you have available for Auto Top-Up.
• Know when you’d manually top up or repay.

Bitcoin’s going to be volatile – it always has been.

The goal isn’t to stop that.

It’s to set up your loan smart enough that a nasty $BTC dump doesn’t end with you on your knees screaming:

WHYYYYYY????!!

Bitcoin Loan Frequently Asked Questions

What happens when a Bitcoin loan is liquidated?

If a Ledn Bitcoin-backed loan hits its liquidation level, Ledn sells enough of your Bitcoin collateral to pay off what you owe, including any accrued interest.

Any $BTC left over is returned to your Transaction Account.

At what LTV does Ledn liquidate a Bitcoin loan?

Ledn liquidates a Dollar Loan at 80% LTV.

You’ll get warnings before that at 70% and 75% LTV, giving you time to add more collateral or repay part of the loan.

How can I avoid liquidation on a Bitcoin-backed loan?

The best way to avoid Bitcoin loan liquidation is to give yourself plenty of breathing room.

Start with a lower LTV, keep some extra $BTC in reserve, turn on Ledn Auto Top-Up, and know when you’d add collateral or repay part of the loan if Bitcoin drops.

How does Ledn Auto Top-Up work?

Ledn Auto Top-Up automatically moves available Bitcoin from your Transaction Account into your loan collateral when your loan reaches 70% LTV.

The aim is to bring your LTV back down toward 65%, as long as you have enough $BTC available.
