Since it's a very small amount, I can lend you 6$ without collateral (I won't have any use for the account) if you can sign from
this address.
Thanks for the offer. But, I don't hold the private key of the address. The private key is held by the satoshicircle website server. That is not possible to sign a message from there. Sorry for that.
Your account don't really worth that much if I am going to accept it as collateral. You can't even prove a signed message. So tell me where are you going to get the payment for this incase you receive the loan?
