Maximum loan amount is determined based on the amount of crypto you hold on your account. The Loan To Value (LTV) is 50%, which means the maximum loan amount is half of the market value of the currency you hold.

I.e if you own a 1.5 ETH (Etherium) and the current unit price in USD is $2,514, so the market value of your crypto equals $3,771 and the maximum loan amount the borrower can request on Lenme is $1,885.5
