I would like to leave a public notice I have been in contact with the OP and he's interested in purchasing 400 bitcoins from me.

I've also read he's talking to other sellers for similar amounts... What is exactly happening? I was given the impression the sale was to be conclusive.

If anyone else is planning to "meet with him to check the cash" in Switzerland, not using a trusted escrow and getting soothed in the large fee promised, I advise you to be weary of your very own life, aside of course your bitcoin.

OP please shed some light on this matter. Are you hoarding a bunch of potential vendors for precautionary reasons or is this all a honeypot?
