I applaud your faith in btc when doing business. But remember where you are: this is bitcointalk, not ebay. Bitcoin is anonymous and untraceable, so doing business is very risky. You should expect to prove your credibility when dealing making deals of such value and not be offended since you will find no shortage of paranoid business partners here. This community, open discussion, and an extensive history are the honest man's best defense against getting ripped off. Im not rushing to judgement, but anyone who attempts to scam should be flagged
