A direct p2p transaction for a property with limited overhead for both parties ..this is deserving of much more attention!!
*snip* ..no matter if i exchange it to dollar bills, camels, bitcoins or art sculpture, it is just an agreement. Thank you for question.
I understand you're asking 200 BTC for the apartment, but I'd like to know how many camels you'd like?
What is this other project? BTC related? I hope you are able to sell your apartment. Good luck to you!
