For the domain name, PM me with proof of funds.
Since the price you're trying to sell it for is "
too good to be true", you should probably reconsider that part and list your domain name so we could check if it belongs to those that actually purchased the previous version of bustabit or it's among the fraudulent sites? If it checks out, then buyers would probably ask for proof that the domain is under your control, prior to proceeding to the next step which is the actual deal with the involvement of the escrow provider.
It's not too good to be true. BTC has risen a lot, so my price is quite a reasonable discount if you think in terms of purchasing power (USD).
I am willing to disclose the domain name to interested buyers in private. I would not want it posted publicly since I'm brokering the deal for a friend and don't want my price undercut. In any case, this price is the cheapest on the market.
Like I said: I am happy to use a Bitcointalk middleman for all of this. I don't expect anyone to go first with a fresh account.
