The OP has not been online for over 3 days. He also PMed me requesting a loan of $1,500 with the same collateral while he had a thread to buy 4 bitcoins.
Smells like a scam to me.
Please reference the thread in which he was asking to make a purchase of 4 Bitcoin. I looked and did not see it, but I did not do a thorough search. Thank you in advance.
