TL;DR
Choose BTC collateral to retain your Bitcoin exposure, or ETH collateral to retain your Ethereum exposure while borrowing. Compare the lender's terms, your room for price declines, and how much of each asset you want to use as collateral. Neither asset makes a crypto loan cheaper or safer by default.
On Liquidium, both have 65% maximum LTV and a 74% liquidation threshold. You can also use BTC and ETH together in Advanced to support borrowing through one portfolio.
- BTC: use the Bitcoin you want to keep. On Liquidium, you can deposit native BTC without first obtaining an Ethereum-based Bitcoin token.
- ETH: use native ETH as collateral and keep enough ETH in your wallet for gas.
- Both: supply BTC and ETH in Advanced to combine eligible collateral. Adding collateral can improve portfolio health, but both assets can fall together.

Bitcoin-backed vs Ethereum-backed loans at a glance
Assets and networks
- BTC collateral: some lending routes require a Bitcoin token on another network. On Liquidium, deposit native BTC on the Bitcoin network and borrow supported assets such as USDC or USDT on Ethereum.
- ETH collateral: deposit native ETH on the Ethereum network and borrow from the same supported stablecoin pools. Our ETH-backed loan guide covers the setup.
Wallet and access
- Simple: create a dedicated loan with one collateral asset, without signing in or connecting a wallet. You still need to send funds and provide destination and collateral-return addresses.
- Advanced: sign in with Internet Identity, using Google, Apple or a passkey, or connect a supported wallet. Supply collateral and manage balances and debt in your portfolio. Use this mode to combine BTC and ETH.
Asset-specific tradeoffs
- BTC: funding starts with a Bitcoin transfer. Allow for confirmations before Liquidium finalizes the deposit.
- ETH: funding uses Ethereum. Native ETH destination and collateral-return addresses must be standard Ethereum wallet addresses; smart contract wallet addresses are not supported.
Liquidium uses chain-key assets internally for its cross-chain borrowing routes. You do not manage that conversion for native deposits. Direct ICP routes use different assets and addresses.
Volatility: compare the loan's downside, not just the asset
A Bitcoin-backed loan keeps you exposed to BTC's gains and losses. An Ethereum-backed loan does the same for ETH. Compare how a decline would affect your debt, rather than assuming either asset is safe collateral.
Stress-test both assets at a 20% decline, then test a steeper drop in either one. Those are hypothetical scenarios, not forecasts or a ranking of their historical volatility. Borrowing capacity can start at the same level while the two positions take different paths toward liquidation.
LTV and liquidation: the same limits, different price exposure
Loan-to-value, or LTV, is debt divided by collateral value. Maximum LTV sets borrowing capacity. The liquidation threshold is the level where collateral can become eligible for liquidation.
Liquidium's BTC pool and ETH pool both allow 65% maximum LTV, with a 74% liquidation threshold. Simple requires an opening buffer of at least two percentage points below maximum LTV. Other platforms set their own limits.
Suppose you supply $10,000 of BTC or ETH and borrow 4,000 USDC. Assume USDC stays at $1 and ignore network costs:
- The 0.5% activation fee adds 20 USDC, so starting debt is 4,020 USDC and starting LTV is 40.2%.
- If your collateral falls 20% to $8,000, LTV rises to 50.25%, before further interest.
- At a 74% liquidation threshold, unchanged debt reaches the threshold at about $5,432 of collateral value. Accruing interest would bring that point closer.
At a 40% collateral decline, LTV reaches 67%: above the opening limit but still below the liquidation threshold in this simplified example. That gap is a buffer for price moves, not extra borrowing capacity.
The app defaults to Health %, with 0% at the liquidation threshold. Decimal Health Factor uses 1.0 for the same point. See the Health Factor guide before comparing the two scales.
Use BTC and ETH together in one Advanced portfolio
Liquidium Advanced lets BTC and ETH support the same debt. Each remains a separate supply position within one shared portfolio-health calculation.
Using the example above, adding $5,000 of ETH to a portfolio with $10,000 of BTC and 4,020 USDC of debt raises collateral value to $15,000. LTV falls from 40.2% to 26.8%, before interest and price changes. Both pools' current liquidation thresholds are 74%, so the weighted threshold also remains 74%.
Adding collateral without increasing debt creates that buffer. Replacing some BTC with the same dollar value of ETH would not. Both assets can fall together, so a mixed portfolio still needs room for losses.
Use Advanced for this combined-collateral flow. Our native BTC and ETH borrowing guide covers deposits and setup. Wait for both supplies to become active, then review projected portfolio health and the borrowing quote before confirming.
Borrowing rates and liquidity depend on what you borrow
Using ETH as collateral does not mean paying the ETH borrow rate. For a USDC loan, compare the USDC borrow APY, whether you supply BTC, ETH or both.
The current Liquidium Insights snapshot lists:
- USDC: 5.205% variable borrow APY; 85.31% pool utilization.
- USDT: 4.084% variable borrow APY; 69.43% pool utilization.
Utilization is the share of supplied funds already borrowed. USDC's higher utilization leaves less idle liquidity as a percentage of deposits. Check the live quote: collateral, pool caps and available liquidity can all limit your amount.
Liquidium adds a 0.5% activation fee to each requested borrow in the borrowed asset. That fee becomes debt and accrues interest. Network costs are separate; check the amount delivered after any outbound fee. The Advanced borrowing guide explains the quote.
Repayment and access to your collateral
These variable-rate pool loans have no fixed maturity. You can repay part or all of the debt, while interest accrues on the amount outstanding.
For Simple, partial repayment reduces debt but does not release collateral; full repayment returns it after processing. For Advanced, repayment and withdrawal are separate steps. You can withdraw eligible supplied assets only when liquidity and portfolio health allow it.
Repay in the asset and network shown for the position. A pending transfer does not reduce active debt until Liquidium confirms and finalizes it, so leave time to repay or add collateral before health becomes critical.
Choose collateral from the assets you already hold
Use BTC if it is the asset you hold and want to retain exposure to. Consider ETH if that better fits your holdings and other plans. Use Advanced when you want both to support borrowing.
The larger decision is how much debt to take on and how you will repay it. If you cannot tolerate a forced sale of the collateral, compare borrowing against Bitcoin with selling a portion before committing it.
Open Liquidium to compare BTC and ETH collateral, review the current quote, or select Advanced to use both in one portfolio.
FAQs
Is BTC or ETH better collateral for a crypto loan?
Neither is the best choice for every borrower. On Liquidium, both currently have the same LTV limits. Compare the assets you hold, price risk, opportunity cost and repayment plan.
Can I use BTC and ETH to support the same loan?
Yes, through Liquidium Advanced's shared portfolio-health calculation. Eligible BTC and ETH supply positions can support the same debt. Simple Loans use one collateral asset per loan.
Can I borrow stablecoins against Bitcoin or Ethereum?
Yes. Liquidium supports borrowing USDC or USDT against eligible BTC or ETH collateral, subject to current liquidity and limits. For USDC debt, compare the USDC borrow rate whether you supply BTC, ETH or both.
Do I need wrapped Bitcoin to borrow against BTC?
You do not need to obtain or manage wrapped Bitcoin before using Liquidium's native BTC deposit route. Liquidium uses chain-key assets internally. Other platforms may require a supported Bitcoin token; compare the route and its trust assumptions before transferring funds.
