Using your crypto holdings as collateral to borrow funds can be a smart strategy. Instead of selling your assets, you lock them up and borrow stablecoins or other tokens, giving you liquidity while you stay exposed to potential price gains.
This approach can boost returns if done wisely, but it also carries risk — especially if prices fall. Here’s a clear guide to the best altcoins to borrow against and how you can use them to maximise returns.
What It Means to Borrow Against Crypto
When you borrow against crypto, you deposit a digital asset (like ETH or SOL) as collateral on a lending platform. In return, you get a loan in stablecoins (like USDC or DAI) without selling your holdings.
This is useful if you want cash flow or funds for investment without triggering a taxable event from selling. The amount you can borrow is defined by the loan-to-value (LTV) ratio — higher quality assets usually allow better LTVs.
1. Ethereum (ETH) — The Most Widely Accepted Altcoin
Ethereum (ETH) is the top choice for borrowing because it is the second-largest cryptocurrency and has deep liquidity across most platforms. It’s widely accepted as collateral on major DeFi and CeFi lending systems, like Aave and MakerDAO, making it easy to get competitive loan terms.
- Why ETH? Strong market presence, broad support, and deep liquidity help ensure better rates and lower liquidation risk.
- Best for: Borrowers who want flexible terms and stable demand for their collateral.
2. Stablecoins (USDT, USDC, DAI) — Low Risk, Smart Collateral
Stablecoins are pegged to the US dollar, making them far less volatile than most other crypto assets. Because of this, borrowing against stablecoins often gets you more favourable terms, lower interest rates, and less liquidation risk.
- Why stablecoins? Low price swings make them safe collateral, especially if your goal is consistent returns without big risk.
- Be careful: You often don’t earn high returns on stablecoins themselves, but they can be excellent for yield strategies with borrowed funds.
3. Solana (SOL) — High Speed, High Potential
Solana (SOL) is an altcoin popular for fast transactions and strong ecosystem growth. Many borrowers use SOL and other Solana-based tokens (SPL tokens) as collateral to borrow stablecoins or other assets. Even though SOL can be more volatile, its broad adoption makes it a good candidate for borrowing strategies.
- Key strength: High liquidity and increasing utility within DeFi.
- Risk factor: Price swings are bigger than stablecoins or ETH, so your position needs careful management.
4. Wrapped Bitcoin (wBTC) and Large Cap Altcoins
Although Bitcoin itself isn’t always supported directly on DeFi platforms, wrapped Bitcoin (wBTC) — a tokenised version of Bitcoin on Ethereum — often is. Large altcoins like Binance Coin (BNB), Cardano (ADA), or Polkadot (DOT) can also be used where supported.
- Why wBTC and big altcoins? Their high market cap can unlock good LTV ratios.
- Watch out: Smaller cap altcoins may be riskier due to low liquidity and volatile pricing.
5. DeFi Tokens (AAVE, COMP, UNI) — Yield-Driven Collateral
Tokens tied to DeFi ecosystems — like Aave (AAVE), Compound (COMP), and Uniswap (UNI) — are increasingly accepted as collateral. They are sometimes offered with higher yields when supplied or used in lending strategies, although loan terms may be less stable.
- Why DeFi tokens? They can boost returns if the platform gives rewards or incentives.
- Cons: They are more volatile than ETH or stablecoins, so margin calls and liquidations can happen if prices drop fast.
Tips for Maximising Returns When Borrowing
- Choose the right platform:
Both CeFi (e.g., Nexo, Binance) and DeFi (e.g., Aave, MakerDAO) have pros and cons. DeFi platforms may offer lower rates but require a comfort with wallets and smart contracts. CeFi is easier but sometimes has higher fees. - Watch the interest rates:
Borrowing stablecoins costs interest. Compare rates across platforms — DeFi protocols change them dynamically, while CeFi platforms set rates based on terms and coin demand. - Monitor Price Volatility:
Volatile collateral can trigger liquidations. Keep your LTV low and add collateral if the market falls. - Use borrowed funds smartly:
Borrowed stablecoins can be deployed in yield farms, liquidity pools, or other strategies to generate returns that exceed the borrowing cost.
Risks to Consider
- Liquidation Risk: If the price of your collateral drops sharply, you may be forced to sell at a loss.
- Interest Costs: Borrowing comes with fees and ongoing interest, which eats into your net return.
- Smart Contract Risk: In DeFi, bugs or exploits can impact your positions.
Always assess your risk tolerance and strategy before borrowing against crypto.
Final Thoughts
Borrowing against altcoins can be a powerful way to unlock liquidity and amplify returns without selling your holdings. The best collateral often includes Ethereum, stablecoins, major altcoins, and DeFi tokens, but each comes with its own balance of risk and reward.
By choosing the right assets and platforms — and managing risk closely — you can make this strategy work for your long-term goals.
