He asked about escrow then why didn't you agreed? A $10 escrow fee could have saved your $270 buddy...

Give him one more day to respond and settle, if he does not settle by this time then create a flag against him. Sorry for your loss!

So sad to hear it. He was asking me a loan of 0.045 BTC around three weeks ago and I was offering him 0.005 BTC or something. Good thing that he did not take that but emphasizing for the amount he was asking. At the end I really did not bother much.

But let's not get too much hopeless, I hope he will come back and settle it. I noticed he has some good feedback after all.

I made a similar mistake once, giving a loan to a member based on his green trust--and I should have known better, too.  I tagged this guy but I'm hoping he'll resurface and pay what he owes you, though if he disappeared right after you sent him the bitcoin I wouldn't get my hopes up.  Sometimes we have to learn very expensive lessons.

And you would think that should count for something, but with account sales rampant you never know exactly who you're dealing with.  I'm not saying that's the case here, but in general it's true.  He has some recent positive feedback, but who knows if he planned to earn that as a way to boost his trust score in order to scam or something like that.  Scammers tend to pull tricks like that.

Always use Escrow man. If he refuses escrow then you saved yourself from losing money. No escrow=no deal.

@OP, I'm sorry for your loss.  You should create a flag as well, here's the link: https://bitcointalk.org/index.php?action=trust;addflag=949547

Zerbis sent me a PM on the 9th asking for a 0.025BTC loan.  When I rejected his request for a no-collateral loan he offered some shitcoin as collateral.  His trade history made me consider it, although briefly.  I rejected his request due to his activity, and the only exchange that has buy orders for that shitcoin is Yobit.

Due to his lack of recent activity and the amount he was asking for, I felt there was a strong possibility he was gearing up for an exit scam.  I hope I'm wrong, and he'll be back to compensate you for your loss.

He played it quite smart though. Went in the Collectables section, won an auction of 0.01 BTC, got some red trust and used that to scam you. Not sure why you didn't go for the escrow. Don't trade blindly with anyone just because they have a green trust. Check for the reputation of the account on the forum as a whole.
