Why borrow against Bitcoin instead of selling it?
For long-term holders across Asia, selling Bitcoin to raise cash has two big costs: you lose future upside, and in many countries the sale is a taxable disposal (e.g. Japan taxes crypto gains as miscellaneous income up to ~55%, India at a flat 30% plus 1% TDS, South Korea at 20% above ₩2.5M from 2025). A loan sidesteps both — you keep the BTC and, because borrowing is not a sale, you generally don't realize a capital gain.
- Liquidity without selling — fund an emergency, a business, or a property deposit while keeping your stack.
- Usually no taxable event — a loan is not a disposal in most jurisdictions (verify locally; see our Asia tax guide).
- Keep the upside — if BTC rises, your collateral appreciates while you hold the loan.
- No credit check on-chain — your Bitcoin is the collateral, not your credit score.
How a Bitcoin-backed loan works
You lock BTC as collateral and receive a loan in cash or a stablecoin like USDT. The key numbers:
| Term | What it means | Why it matters |
|---|---|---|
| Loan-to-Value (LTV) | Loan ÷ collateral value | Lower = safer. 20–30% is conservative; 50%+ liquidates easily. |
| Interest (APR) | Cost of the loan per year | Typically a few % to low-teens; stablecoin loans are often cheapest. |
| Margin call | Warning when LTV gets too high | Add collateral or repay — or face liquidation. |
| Liquidation price | BTC price that triggers a forced sale | The single number to watch. Keep a wide buffer. |
Example: post 1 BTC as collateral and borrow at 25% LTV. Bitcoin would need to fall a long way before you near liquidation — versus a 50% LTV loan that a normal correction could wipe out.
CeFi vs DeFi / BTCFi — where to borrow
| CeFi (custodial) | DeFi / BTCFi (non-custodial) | |
|---|---|---|
| Who holds your BTC | The company | A smart contract you can verify |
| Counterparty risk | Yes (Celsius, BlockFi failed in 2022) | No company to fail |
| Rehypothecation | Possible | No |
| New risks | Opaque reserves | Smart-contract & oracle risk |
| KYC | Usually required | Often none |
| Liquidation risk | Yes | Yes |
In 2026, BTCFi (Bitcoin DeFi) has grown to billions in total value locked, with Bitcoin-secured infrastructure like Babylon enabling lending and yield without handing over your keys. Whichever model you choose, transparency and a conservative LTV matter more than the headline rate. Learn the landscape in our Bitcoin DeFi / BTCFi guide.
Sell vs borrow vs HODL
| Sell BTC | Borrow against BTC | Just HODL | |
|---|---|---|---|
| Get cash now | Yes | Yes | No |
| Taxable event | Yes (capital gains) | Usually no | No |
| Keep BTC upside | No | Yes | Yes |
| Liquidation risk | None | Yes | None |
| Best for | Exiting the position | Short-term liquidity, high conviction | Long-term savings |
The risks you must respect
Borrow smart — but save in self-custody first
A loan is only as safe as the stack behind it. Hold your long-term Bitcoin in self-custody, borrow conservatively only when you have high conviction, and keep a buffer to top up collateral. The goal is to use your BTC without ever being forced to sell it.
