Using crypto as collateral – what actually happens when the price drops and how to protect yourself

Most explanations of crypto loans focus on the upside. This one is specifically about the downside – what the liquidation process actually looks like and how to avoid it.

The basic mechanic when price drops: your collateral value falls → LTV ratio rises → at a threshold the platform warns you if you don't act (add collateral or repay partial loan) → they liquidate.

Multi-stage process most platforms use:

Warning (~75–80% LTV) – notification sent. Still plenty of time to act.

Margin call (~80–85% LTV) – prompted to add collateral or repay. Usually given hours to a day or two.

Liquidation (~90–95% LTV) – platform sells enough collateral to bring LTV back under threshold. You lose some or all of your collateral depending on how far it went.

How to actually protect yourself:

Start conservative. 50–60% LTV means you're protected until a 33–40% price drop. Not 85% because 'the market looks stable right now.'

Keep cash on hand. If you borrow $5k against BTC, keep $1–2k in fiat accessible. If BTC dumps 20% you need to act fast.

Set your own price alert. Don't wait for platform notifications. Set a CoinGecko/exchange alert at the BTC price where your LTV would hit 75%. That gives you time before it becomes urgent.

Know if they liquidate everything or just enough. Some platforms liquidate your entire position. Some liquidate only enough to restore the LTV threshold. Massive practical difference – check the specific terms before you open a loan.
