I have sent 1st part of payment 4 hours ago, he said it must last from 10minutes - until 2 hours to receive bitcoins, and now
he is ignoring me on skype. Hope i will receive bitcoins but until then i think im scammed. Is here any admin to react?
This is your problem you should of dealt with a trusted member also you can just charge back the funds. Its funny when scammers scam each other.
