I am going to share his reply because I find it amusing.
Hi sir
On collateral: I've decided to give you a combination of things as collateral. Because the loan is condiserably large.
1. My games accounts and pass.
2. The bitcoin address, including password so you can monitor what i'm doing with the bitcoins.
3. An identity collateral. My facebook account and pass so you can show up and use my account and post stuff if i'm overdue. The account is legit, of course and I think is the most valuable of the 3 collaterals.
Is it a deal? Thanks in advance.
