I have some good domain names (like really good) that I am willing to sell at auction for bitcoins.
Is there a trusted service for this?
This forum has an "Auctions" section. What more can be trustworthy than that? Even theymos runs his own auctions of the forum banner ads there and we see a large volume of bitcoins been paid there.
Of course you should defenitely use an escrow to mediate the trade. Set your own terms and set up a thread following the general rules. Usually domain flippers look into this section, if so you may be in luck.
I dont know of any third party service that allows reselling of domains, because domain names is not my "domain"
But @Jet Cash might be able to give you some good pointers.
