Hello ! I am buying bitcoin from coinbase and do not want to wait a week to receive them. I am looking for 0.005 bitcoin, and when my coin comes in from coinbase (should be a few days it says) I will repay 0.01 to my lender. The only collateral I have is this account, sorry I do not have anything else to offer. I will be using the coins to do some small scale P2P short term lending. If you have any questions feel free to ask.
The only thing that comes to my mind after looking at 2x repayment of original amount is that you will gamble the money and you are quite optimistic that you will win it. Please make sure you either close this request or give some valid collateral else you might get red trust.
