I don't see any mention of a collateral.
Don't expect to loan such an amount without any kind of guarantee..
I can provide vircurex account having 1.57 BTC on balances (frozen for the time being).
Also i offer quite high interest rate - 30% for 3 days.
My bitcointalk account is 1 year old & there is no an intent at my end to take risks of receiving negative trust for the good of $500. I wouldn't be asking for a loan if there weren't decisive circumstances involving me into obligation to immediately repay expenses for the website. I have fiat, but there is no chance to buy bitcoins as swiftly as i need.
Just hit off of a little frustrative combination of facts when run out of spare bitcoins.
