Really don't want to screw your post, but at least one of the auctions looks very scammy because of the bidding pattern. 250BTC is a high price indeed, and those auctions aren't solid enough to base the price on them imo.
I think you could share with us a scenario you expect based on difficulty projection and profitability decline per year factor - if the difficulty goes x2 there you go with 2.5BTC per day, with difficulty increasing week by week, imo that's the more likely scenario.
I don't want to defend any particular ROI scenario at all. That is an area of pure speculation.
Right there. Regardless of what the payback period is, this offer still allows people like myself to be a part of mining (although not a very hands-on one) and be an active part of the bitcoin community. What method will you use for bookkeeping and payouts? Can we request payouts to a particular address? Do you plan to list on btct.co and allow shares to be traded?
Thanks,
Dave
If those answers are not in the original post, I have failed as a writer. That's bad, bad news for a professor.
I will use the blockchain. It will tell who paid, how much they paid, and who I should send the payments back to. It is the full audit trail, and it is viewable by anyone. You are anonymous or not, under your control.
In time, I will write some software to directly read the blockchain and construct the payout TXns. In the present, I will just read on the web and click the mouse endlessly to make things go.
The link in the original post leads to a transaction on blockchain.info that shows when I paid for the avalon. If you create a new payment address that is only used for this venture, the blockchain.info report on that address will show how much you have paid in, and how much your have received back.
I will only pay to the address that bought into the venture. I can manually cash out someone, and they can sign up with a new address, and that will accomplish an address change. For a large group, this will become very tedious.
You can look at the signup address, 17Pq8oPtk8rikxZhF1wENFqR9YtDyLyr8E, in blockchain to see how many people have signed up. It's a pretty quick read right now
I don't envision a way to trade this offer.
