How It Works

You deposit Bitcoin as collateral and borrow USD against it. The Loan-to-Value (LTV) ratio determines how much you can borrow relative to your collateral's value.

🔵
Left Bucket = USD Loan
The amount you've borrowed in dollars. Grows with interest over time.
🟠
Right Bucket = BTC Value
The dollar value of your deposited Bitcoin. Fluctuates with the market.
📊
LTV = Blue / Orange
Keep this ratio low for safety. Auto-liquidation triggers at 86% LTV.

Starting the Loan

Deposit 0.2 BTC at $100,000 per coin. Borrow $10,000 - a 50% LTV.

Loan Amount
$10,000

Collateral

= $20,000

Interest Accrues Over Time

Your loan balance grows each day at 5% APR. The blue bucket slowly fills up, increasing your LTV - even if BTC price stays flat.

BTC Price Drops - LTV Rises

When Bitcoin's price falls, your collateral shrinks. The orange bucket drains - pushing your LTV dangerously higher.

Option 1: Repay Some USD

If your LTV is getting too high after a price drop, you can pay back some of your loan to bring the blue bucket down. This directly lowers your LTV.

Option 2: Add More BTC Collateral

Instead of repaying USD, you can deposit more Bitcoin to increase the orange bucket. More collateral = lower LTV, even at the same price.

BTC Price Rises - LTV Drops

When Bitcoin's price increases, your collateral becomes more valuable. The orange bucket grows - your LTV drops and you're safer.

BTC Up? You Can Borrow More

When your collateral grows in value, you have room to take out additional USD. This increases your loan (blue bucket goes up) and raises your LTV - but you get more cash.

Liquidation at 86% LTV

If your LTV hits 86%, automatic liquidation kicks in. Your Bitcoin is sold to repay the lender. The loan is considered repaid - but you lose your BTC.

The Long Game

If Bitcoin appreciates faster than the 5% annual interest, your LTV naturally decreases - you may never need to actively repay.

LTV keeps dropping!
As long as Bitcoin's long-term growth exceeds the 5% interest rate, the loan effectively manages itself. Your collateral outpaces your debt.
