My only question is, how will the trade go down? Will you be using escrow? Or meeting face to face?
Unsure yet. To be honest though I don't see the need for an escrow, I already have almost 5k Bitcoin from others invested in the site, of which I just divested close to 500 to reduce this amount. So I think it's safe to assume you could trust to just send the amount to me then I transfer the assets.
But something could be arranged if needed.
Without escrow who would go first? Will you receive the payment and then send the ownership of the site? Then the buyer would risk that you are a hacked account only. Of course you could prove the ownership by signing a message with an old posted address.
Besides that... i agree it will be hard to get an escrow for that amount of money. It's fearsome to hold that much i imagine. And even established escrows might run since it might be that that amount of money is enough to throw their morals over board.
As i believe Dean is located in the U.K and if we were to make a deal for the sale of prcdice, i would be willing to go to the U.K and bring my legal team to get the exchange done properly.
Of course i meant a signature. But when they already provided such then this should be sufficient to proov the claims of the website owner.
