Lesson 12. Quick question about on Handler mintDsc

[DownShiftDom]

function mintDsc(uint256 amount) public {
        (uint256 totalDscMinted, uint256 collateralValueInusd) = dsce.getAccountInformation(msg.sender);

        uint256 maxDscToMint = (collateralValueInusd / 2) - totalDscMinted;
        if (maxDscToMint < 0) {
            return;
        }
        amount = bound(amount, 0, uint256(maxDscToMint));
        if (amount == 0) {
            return;
        }

        vm.startPrank(msg.sender);
        dsce.mintDsc(amount);
        vm.stopPrank();
    }

Can someone explain why in the following code

uint256 maxDscToMint = (collateralValueInusd / 2) - totalDscMinted;

we divide collateralValueInUsd by 2? Sorry if this is a silly question. Its currently 1am for me and my brain is malfunctioning lol

Suppose you deposited 100 USD worth of collateral which means you can only mint DSC half of the value of your collateral because protocol is 200% collateralized. So to determine the amount of DSC you can mint you divide it by 2 -> (collateralValueInusd / 2) and then you minus the amount of DSC you already minted -> (collateralValueInusd / 2) - totalDscMinted.

Thank you for clearing that up! forgot about the liquidation threshold! oops.
