I will send you the same day or within some hours after you send me the Bitcoin.
Absolutely not happening! Are you sober? High on something? Ever heard of escrow? Or do you know about it and you're pretending it doesn't exist? Why should anyone send you bitcoins first? How is the seller protected? With your worthless word alone?
Use escrow or nobody should send any coins to your wallet upfront! Your documents mean nothing. They could be anyone's documents. Or even fake ones. What can the seller do with that passport if you fail to deliver as agreed? Auction it off to recover the stolen coins?
Advice to everyone: do NOT send any coins without escrow protection to this guy's wallet unless you want to donate them!
