What would prevent you from using the coupon after the user sends you the loan? For what would you use the loan this time, anyways? Are you still trying to upgrade your account in the ponzi website? I hope you still don't think risking someone's money in an obvious scam is a good idea.
Hell NO! I reported that site BTW. The ONLY site I would use it (the collateral) IS on hashaltcoin.com for a Blackminer F1 mini (on NO other site)
hashaltcoin.com sells asic miners (they are legit)
