0% APR Crypto Loan: LTV-Gated Credit Lines and LTV Drift Risk

A “0% APR crypto loan” is not automatically free. In 2026, the effective cost mainly depends on LTV (loan-to-value), the loan structure, and how much liquidity you actually draw. New emphasis in the later article: platforms often use an LTV-based lowest-rate tier (e.g., around LTV ≤ 20%), so falling BTC/ETH prices can push borrowers into higher APR tiers or trigger liquidation—making LTV drift a direct cost risk. For traders, the structure matters as much as the headline rate. A credit line can charge interest only on the drawn portion, while unused credit can remain at 0% APR, improving capital efficiency versus a term loan that accrues interest on the full borrowed amount from day one. The article also frames these loans as a liquidity buffer: borrow partially, monitor LTV actively, add collateral or repay to stay in the low-cost band, and avoid long-term full utilization. Multi-collateral setups (BTC + ETH + stablecoins) may help smooth collateral volatility and reduce sudden LTV spikes. Example: “Clapp” is cited as using LTV-based pricing and 0% APR on unused credit, but the takeaway remains the same—discipline is required. If managed poorly, even a 0% APR crypto loan can become expensive through LTV drift and liquidation risk rather than interest alone.
