2) Enter the amount you want and click "Borrow" to complete.

Please pay attention to the loanable assets, loan utilization rate, and health factors displayed on the page.

The loanable asset represents the maximum amount of the asset you can borrow.

Loan Utilization Ratio Loan: Utilization Ratio=actual loan/ loan limit*100. Users are requested to pay close attention to the loan utilization ratio. If the utilization ratio is close to 100%, it will trigger liquidation. The utilization ratio within 80% is relatively safe .

Health factor: Health factor=(1-utilization ratio) * 100%. When the health factor is close to 0, it will face the risk of liquidation.
