I have attended auctions for many years.  People bid more if they see the competition.
You could post a payment address and let the community decide.

I am a possible bidder.  I am collecting funds for a consortium.  You can view how well the collection effort is going on the blockchain.

In his auction, that is cyberaa's call.

However, tell me what should happen to them.

In another thread, I proposed using the blockchain to make the bids.  This is the ProfMac style auction.

To do that here, OP would create a new payment address for this auction.  To bid, you would just send (0.000 1 * your bid) to that address.  To bid BTC 50, you send BTC 0.05.  To bid BTC 80, you send BTC 0.08

The blockchain makes a nice timestamp and all the action is public.  You are anonymous.

The winning bidder puts his Name, address, and contact info in a message and signs it with his payment address.  He sends that in a PM.

Most of the administrative paperwork is taken care of automatically by the block-chain.  We know the payments are real--though we don't know who made them.

There is activity in my PM on the issue of buy-back.  One concern is that I will contrive a "free loan" and another concern is about how the timing plays out between income to the venture and any payback that I initiate.

I tried to make a sensible offer up front.  
I think that people get uncomfortable if the offer changes after they have put money in.
I tried to make the rules minimal, because the more complicated they are, the more difficult it is to understand them.
I was in a hurry to try to fund a batch #3, so there is always a chance that I crafted a really bad rule in there somewhere, I hope not.  

So here are some scenarios:

1.  Spring flood puts my house underwater.  I can't mine any more.  I refund everyone their coin.  This scenario is covered under the offer.
2.  Drama Queen makes a purchase, and takes a vastly excessive amount of attention.  I refund him his money, and everyone can read the bit-chain and verify this.  It's covered under the offer.
3.  A big payment comes in, and I don't want to share.  I refund everyone's money.  Oops!  The epoch ended when the payment came in, I can't manipulate things this way.
4.  Snipe wants to buy in as late as possible so that he gets paid without having his coin tied up.  I think he has a chance of missing a payment by buying in late and that offsets the advantage he might get by buying late.  I thought the rules were "good enough" to handle this.

5.  Greed tries to buy 300% of my production.  Hmm.  I can refund back down to about 90% sold out.  I can keep the coin and buy more hashing power, provided that the pay schedule is met.  Both scenarios are ok with the rules of the offer.

6.  Hopper wants to get their money back and move on.  I'll try to be cool.  If I can buy back,  I'll announce a buy-back here even though I don't have to.  I'll refund everyone who bought in more recent than the bored dude.  Everyone then decides if they really want back in, want back in stronger, or whatever.  It's covered under the scenario.  It is a tad tedious.  This is the place where I will tweak the rules in any new venture.

There is a Batch #2 pre-order for sale.  Woo Hoo!  Buy shares now!

I don't think making more and more rules makes a deal safer.  That goes for any deal, not just this one.  Honey scammer don't care.  Ultimately, you have to trust the good guys and distrust the bad guys.  Good luck if figuring out who is who.

I'm interested in crafting the rules for deals, so I welcome discussion on this, and I will tweak the rules for the next venture that I start.

That is public knowledge.

I see numbers of about 65 Gh/s quoted for the Avalon Batch #2 unit.
The entire output of the unit is set at 100 shares.

I think that comes to 650 MH/s  / share

It would be interesting to calculate how many high end Radeon GPUs 1 share is equivalent to.

I was not able to find a price for this model in their shop.
I had wanted to look at the cost and estimate the income, but did not find either answer quickly.

I think the Avalon Batch #2 is supposed to ship soon.  I don't understand why you think it will be 50 days before it mines a block.

Exposure to the bitcoin community causes many people to begin using the word "scam" to mean "any deal where I don't already have the profit in my own pocket."

There are some things to keep in mind:

Others have already bought in.
You cannot take possession of the device.
I have a buy-back right against your shares.

Since I already have a paid order for the Batch #2, I will deliver what I promised.

So long as I have not spent the coin on Batch #3, I don't mind returning money to anyone who wants out, for any reason.

Batch #2 did re-open after Avalon did an audit on the orders that were paid or not.  So I suppose I should still try to gather the BTC 75 or so in case a Batch #3 becomes available.

After our shooting I spent a lot of time at the courthouse.  There is a lot of people watching there.  Another father lost a son in another case, and he was deeply (and justifiably) angry.  He wanted revenge.  It ate at him, and it worried everyone in the courthouse:  none of us wanted to be in any crossfire.

I wanted my daughter back.  Nothing else, only that.  I was clear that revenge would still leave her dead.

Both cases proceeded to a guilty verdict.  I was relieved that the trial was over, and I could spend time on the rest of my life, heal, find out who I was without my kid.  The other case also proceeded to a guilty verdict, with a death penalty.  That father just crumpled at the verdict:  he got what he had pursued for almost 2 years, and only when he had it did he realize it had no value to him.

Do you want Roman to be out of business?
Do you want him to be publicly humiliated?
Do you want him to be shut down?
Would you accept it if Roman is successful and repays everyone in time?

I like the idea of buying the debt.  I would make it a negotiable thing, and buy and sell it on an exchange.  It would end up in the hands of the people who can carry it, and those who have a liquidity crisis would get some liquidity now.  Bah, it sounds like I believe in markets.

My dad started as a lineman, and worked up the chain to become an EE and design transmission lines.
I actually did work as an electrician's helper for a year.  Plugging & Switching, they called it.  Had pretty fast dykes and Kleins.

What can make you satisfied?

They usually run 17,500 V on top of a pole.  This is from memory and I could not verify it just now--it may be 11,000V.  There are step down transformers every so many houses that feed 3 wires, presumably 240 V + neutral.  Every so many blocks the 17,500 is 3-phase.  There is attention to keep all the phases balanced and in phase.

I'm really glad to see a positive community action in the bitcoin world.

The (molar) heat capacity might also be useful.  For background, read up on Trouton's rule.  The data you can collect at home is to heat your coin in boiling water, measure the temperature, put the coin into a thermos with a known amount of water, and measure the temperature rise.  You might want to arrange the volume of water so that the start and end temperature are on scale with a digital fever thermometer.

Then make a 2D plot, with density and heat capacity as the two axis. 

Any method that you use will easily detect some problems, and be blind to others.  Your own personal crooks will specialize in the blind spots that you have.  It is a locksmith - thief race.

Wise man.

Also, I have substantially changed the opening post.

I have tipped one poster in the past.  You are a candidate for Nr. 2.  But I don't see any payment address in your signature.  I think that if you just update the signature, all your posts will show the new (current) one.

I got this difficulty from https://blockchain.info/stats.  Should I use a different one?

I have run a calculation from this page.
I entered these numbers:

Conversion Rate: 79.99 (The limit sell value on BitFloor at this time.)
Hash rate (MHash/s): 65,000.00 (the advertised rate)
Electricity rate (USD/kWh): 0.08192 (The expensive winter rate.)
Power consumption (W): 650
Cost of Mining Hardware: $1499 (Is there a page that is all BTC based?  I don't need to have USD involved)

Results
Hardware break even:  4 days
Net Profit first time frame (3 months): 31928.05 USD
$31,928.05 / 250 portions = $127.71 / portion = $127.71 paid for bitcoin = $127 / 77.99

That is 63% interest paid in 90 days.  This is not guaranteed.  It is just some numbers plugged into the suggested web page.  It is an illustration for your amusement only.  Things will go wrong.  Things always go wrong.
