can I ask why you PM'd me your (overpriced) price of 4btc with a 'brand new' username? >>> anykeywhy' with an apostrophe? new user registered today?
I have unfortunately seen this type of scam attempt a lot of times lately, I spend quite some time in the "marketplace" section.
All buyers MUST be aware of this.Check and double check that is the right person PM'ing you, especially when the message contain a bitcoin adr.
I think we (as a community) need to use PGP signatures more often.
@OP Good luck with the sales.
