# Costs and Predictability GMX and Similar Futures Platforms: * Costs can be unpredictable due to varying funding rates * Potential for unexpected fees during high volatility periods MortgageFi: * Predictable costs through fixed USD repayments * No hidden or fluctuating fees Example Scenario Imagine Alice and Bob both want to gain leveraged exposure to 3 ETH: Alice uses GMX: * Opens a 3x leveraged long position on 1 ETH * Pays fluctuating funding rates, potentially eroding her position over time * Risks liquidation if ETH price drops sharply Bob uses MortgageFi: * Borrows 2 ETH against his 1 ETH collateral * Makes fixed USD repayments, maintaining his 3 ETH exposure * Can hold his position long-term without fear of liquidation due to price fluctuations MortgageFi offers a more stable, predictable, and potentially less risky way to gain leveraged exposure to crypto assets, especially for users looking to hold positions over longer periods. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
