Yes I can do those things, my collateral is my accounts trust level and casascius physical bitcoins. However I'm cancelling this loan request now as I no longer require it.
Also, I would be hesitant to do any deals with a member who has a trust rating that is in question like yours...
Alright, well let me know if you need a similar sized loan in the future and I probably can help you out.
As an FYI, every person that I have traded with has had a very good experience in trading with me, they always expressed that they were satisfied with the trade, and I have been trusted with large amounts of money without incident.
