How Altcoin-Backed Loans Work
Borrowing against altcoins works like other crypto-backed loans: your digital assets act as collateral. You deposit crypto into a lending platform, receive cash or stablecoins based on a percentage of your collateral's value—called the Loan-to-Value (LTV) ratio—and repay the loan with interest to get your crypto back.
The key advantage: you avoid triggering a capital gains tax event by selling . Under current guidance, borrowing against crypto isn't considered a sale . Plus, there are no credit checks—your collateral does the underwriting.

But altcoins carry specific risks. They tend to be more volatile than Bitcoin and Ethereum. Platforms often set lower LTVs. For example, Coinbase caps XRP, ADA, DOGE, and LTC loans at 49% LTV with a liquidation threshold of 62.5% . Borrowing at a conservative LTV creates a buffer against volatility.
