No matter how much theory you learn, actual operation is still easy to make mistakes. I’ve summarized some issues I encountered when borrowing USD1 with a few friends, and I’m sharing them in a Q&A format. These details are often more practical than grand theories.

**Q1: I’m most worried about liquidation. How should I set the collateral ratio to be safe?**

This is what I care about most. On the Lista interface, there are two key indicators to understand: "Maximum LTV" (usually 75%) and "Liquidation LTV" (usually 80%). Simply put, you can borrow up to 75% of the collateral’s value, but if the collateral ratio drops to 80%, you will be liquidated.

My approach is: never touch this ceiling. I keep my actual collateral ratio within the 50%-60% range. For example, with $10,000 worth of BTCB, I only borrow $3,000-$4,000 of USD1. This way, even if BTC suddenly drops 30%-40%, I have enough time to handle it by adding collateral or repaying early, without panic. If I greedily borrow up to the 75% limit, I’m walking a tightrope.

**Q2: How do I withdraw the borrowed USD1 to the exchange? Is the process complicated?**

Not complicated, but you need to understand the logic. First, you must know which chain the USD1 is on (usually BNB Chain).

The operation is straightforward: after borrowing USD1, it’s in your wallet. Then open the exchange (like a top platform), find the USD1 deposit entry, and transfer the coins from your wallet. The key is not to confuse the chains; transferring coins from BNB Chain to another chain will result in a direct loss.
