                    taken, and the trader must have at least this amount in
                    their wallet to open the loan. It is advised to have at
                    least 10% more than this, to protect for price fluctuations.

                    An amount of collateral equal to the Initial Margin Amount + 
                    the total value of your loan, will be escrowed. Please ensure you

                    withdrawn to your wallet. If you don't return the full amount of loan
                    token before the loan term ends or the loan gets liquidated, you will 
                    lose a large portion of the collateral in order to compensate the lender
