Doubts in the Project Decentralzied Stable Coin concept

[farman1094]

I have 100's of questions regarding the liquidity but I would like to ask this first, maybe this answer my another questions.

So I have doubt regarding the main concept of liquidity in DSCEngine

So you can see the Scenario Here is the code of my test of liquidity

 function testForLiquidityPass() public { 
    //setup
        vm.startPrank(USER); 
        ERC20Mock(weth).approve(address(engine), 1 ether); 
        engine.depositCollateralAndMintDSC(weth, 1 ether, 1000 ether); 
 
        int256 updateAnswer = 1500e8; 
        MockV3Aggregator(ethUsdPriceFeed).updateAnswer(updateAnswer); 
        // uint256 userHealthFactor = engine.getHealthFactor(USER); 
        vm.stopPrank(); 
 
        vm.startPrank(liquidator); 
        ERC20Mock(weth).approve(address(engine), 2 ether); 
        engine.depositCollateralAndMintDSC(weth, 2 ether, 1000 ether); 
        dsc.approve(address(engine), 1000 ether); 

        (uint256 userBeforeLiquidityDSC, uint256 userBeforeLiquidity)= engine.getAccountInformation(USER); 
        (uint256 liquidatorBeforeLiquidityDSC, uint256 liquidatorBeforeLiquidity)= engine.getAccountInformation(liquidator); 
        consolesBefore(userBeforeLiquidityDSC,  userBeforeLiquidity,  liquidatorBeforeLiquidityDSC,  liquidatorBeforeLiquidity);
        
        //liquidate
        engine.liquidate(weth, USER, 1000e18); 
        
        //Effects
        (uint256 userAfterLiquidityDSC, uint256 userAfterLiquidity)= engine.getAccountInformation(USER); 
        (uint256 liquidatorAfterLiquidityDSC, uint256 liquidatorAfterLiquidity)= engine.getAccountInformation(liquidator); 
        consolesAfter(userAfterLiquidityDSC, userAfterLiquidity, liquidatorAfterLiquidityDSC, liquidatorAfterLiquidity);       
        vm.stopPrank(); 
    }

So according to this Scenario as per above. The question arise is

Why someone lock their $2000 just to get $1100 ??
Please help me understand this, am I missing something or have I understand something differently?

Thank you for responding and your precious time. 🙏

Hello @farman1094, The codebase is far from being a production codebase, and honestly, many things weren't considered in the codebase. So I will say understand the concept of what the codebase teaches, and you can work to improve anything you think isn't properly implemented.

i thought @PatrickAlphaC was tryna get the codebase audited ?

[EngrPips]

Yeah, he did.
