The collateral also include source code. once default the loan, lender can sell it with whole project.
To be honest i hope find an buyer who can continue to manage this project. but now only lend choice.
That means that you don't have any plans to pay your loan and just leave your website to the lender which is not a good at all, remember they lend money and expect to get their money back with certain in returns.
Don't make them sell your project since in the first place you struggle to sell it and since no one got an interest to buy it better to sell it at much cheaper price to see if someone will show a interest to buy your website.
