Lending and borrowing are like octopus tentacles wrapping around themselves; the more you borrow, the harder it is to control. When the liquidation line is three steps away from the red line, I usually stop first: don't add leverage anymore, don't say "just a little more." Then do two things: first, review the collateral/debt structure, repay a little if possible, or simply add some margin to pull the line further away; second, set the alert threshold earlier, so you don't find yourself underwater when a sudden wind blows on the chain... Especially recently, as everyone tests the testnet incentives and keeps flipping back and forth, and guessing whether the mainnet will issue tokens, I definitely don't dare to add this uncertainty into the liquidation risk. Be more cautious, don't gamble.
