How Do Crypto Loans Work?

A crypto loan is a short- or medium-term advance of cash or stablecoins secured by your digital assets. You deposit tokens into a lending platform, pick a loan-to-value (LTV) ratio, and receive funds within minutes. While the loan is open, you keep market exposure but cannot move the collateral.

Crypto borrowing generally falls into three categories. Each offers a different mix of speed, cost, and control.

• Centralized loans (CeFi) - Offered by custodial lenders such as Nexo, these loans resemble traditional lines of credit. Some exchanges have offered crypto-backed lending products, and product availability can change by jurisdiction.

• Decentralized loans (DeFi) - Powered by smart contracts on protocols like Aave and MakerDAO, DeFi loans require no identity checks. You lock tokens in a contract, mint or borrow

  stablecoins, and manage everything from a Web3 wallet. Rates and loan-to-value ratios float with on-chain supply and demand, and you must monitor liquidation thresholds yourself.

• No-collateral flash loans (advanced DeFi only) - Available on protocols such as Aave, flash loans let developers borrow millions for a single blockchain transaction without posting collateral. The borrower must repay within that same transaction block. Otherwise, the entire operation reverts. Flash loans are popular for arbitrage, refinancing, and DeFi liquidations but typically require coding skills and carry high technical risk.

Centralized crypto loans vs DeFi crypto loans

• Liquidity without selling or triggering capital gains

• Faster approval and fewer credit checks than bank loans

• Flexible repayment schedules on many platforms

• Potentially lower rates than unsecured credit cards

• Continued upside if the collateral rises in price

• Collateral is locked and cannot be traded or staked

• Price drops can cause margin calls and liquidation

• Interest accrues daily; fees vary by platform

• Counterparty risk on CeFi platforms

• Smart-contract risk on DeFi protocols

What are the risks of crypto loans?

• Market risk: steep price swings can liquidate collateral.

• Platform risk: lender insolvency, hacks, or new regulations.

• Code risk: bugs or exploits in DeFi smart contracts.

1. Compare CeFi and DeFi platforms for rates, LTV, and supported coins.

2. Complete KYC (CeFi) or connect a Web3 wallet (DeFi).

3. Deposit collateral and choose loan currency.

4. Receive stablecoins or fiat and monitor the health factor.

5. Repay the principal plus interest to unlock the collateral.

• Supported collateral: BTC, ETH, or platform-listed altcoins

• Minimum deposit: often $100–$500 equivalent

• Maximum LTV: 30–75% depending on volatility

• Residency: some platforms restrict certain US states

• Age and identity verification for CeFi services

How much collateral is needed for a crypto loan?

Collateral is what you put up to receive a loan. Collateral requirements vary by platform and asset. A common range for major coins is roughly 30% to 75% LTV (about 133% to 333% collateralization), with lower LTVs often used for more volatile assets.

Be prepared for this and understand the collateral requirements before engaging with a crypto loan platform. You’ll want to know what you’re putting at stake before taking out any loan.

• CeFi lenders: Nexo, Coinbase, Ledn, Binance

• DeFi protocols: Aave, Compound, MakerDAO, Spark

• Flash-loan venues: Aave, Balancer (advanced users only)

Borrowing is tax-neutral, but taxes apply if:

• Collateral is liquidated at a gain (capital gains tax).

• You repay with appreciated crypto (gain at repayment).

• Business borrowers may be able to deduct interest and certain fees on the return for the related activity (for example, Schedule C for a sole proprietorship), depending on the facts.

• Personal loan or HELOC from a bank

• Brokerage margin on traditional securities

• Selling a portion of your crypto holdings

• Peer-to-peer fiat lending platforms

• Credit-card cash advance (typically high interest)

Pro tip
Always do your own research and understand the risks involved before investing in crypto or taking out any kind of loan, crypto or otherwise.
