Just curious... What if this type of language was put in the next auctions?

The auction will end ****. Each valid bid will delay the end time by another hour.

262  Economy / Digital goods / [WTS] Bitcoin Betting Exchange/Prediction Market - Site to earn Bitcoins! on: April 29, 2013, 08:20:09 PM
I would like to offer a complete and fully functional Bitcoin Betting Exchange/Prediction Market for sale.

Intrade is gone, Bitcoin rules, but parimutuel sucks
Since InTrade has disappeared, I think Bitcoin has a huge opportunity to show the way in peer-to-peer betting. The problem is that the current model dominating on bitcoin sites (parimutuel betting) is unfit for serious betting. What is needed is a proper Betting Exchange!

A betting exchange is a peer-to-peer platform for betting: instead of betting against the house, the users bet amongst each other. A betting exchange is much more flexible than existing bitcoin betting sites in that it allows multiple outcomes and also allows the users to bet at the odds they like.

The site operator earns money on charging a small commission on winnings, rather than being a counterparty to the bets like a traditional bookmaker.

It is a well-established and popular form of betting: check out http://www.betfair.com/ and http://www.betdaq.com/ for successful non-bitcoin examples.

The bets that can be made on the site can be anything from sports to politics to financial bets - it all works the same.

Advantages of Betting Exchanges
  • Peer-to-peer betting gives great odds and no "house edge"
  • Users set their own odds
  • Allows betting for or against each outcome
  • Enables users to trade and arbitrage
  • Bets are between users, site operator has no risk

The Advantages of Using Bitcoin for a Betting Exchange
  • Simple: no signup, registration or login needed to bet means low barriers
  • Security: no personal information, credit card numbers or bank details are needed
  • Accessible: open to a worldwide audience
  • Users can be as anonymous as they like
  • No frozen assets
  • Instant payouts
  • Low fees
  • All customer funds sent directly to an offline wallet

Great idea, but why sell if it's already finished???
I believe the site could be a great success if run by the right person (I would in fact be a big customers myself). It would enter the void left by the Intrade shutdown, and help show the world the power of Bitcoin. I expect it would also generate a handsome profit through commissions taken off the winnings. It has been developed after the model of Betfair and Betdaq (links above) - which are reputable and highly successful (non-Bitcoin) betting platforms. The exchange I have developed essentially clones their functionality, but brings in the power of Bitcoin.

I have developed the site/software myself over the course of one year, with the intention of running it myself. However, am am now looking to sell because I realize I simply do not have the time to operate such a site.

I prefer to sell to a trusted community member who understands the concept well and has (access to) the necessary technical expertise to run the betting exchange.

Technical Info
Built on Lighttpd + web.py + Twitter Bootstrap + mySQL. Users funds stored entirely in cold wallet. Fully functional, very polished and well-tested. Some rebranding probably necessary, but essentially ready to launch.

DEMO
Yes. Demo is available, please PM me!

Price
Negotiable. Escrow encouraged.

Please feel free to ask any questions, either in this thread or by PM.

Edit: Forgot to say that it also allows user-created events, and will share the commission between the event creator and the site owner.

I believe selling or mining isnt the question. Mining has to be more profitable all the time because any sane miner only will buy the miner when he see the chance to meet ROI in a certain amount of time. Otherwise mining is only something for fans of a product or contributors to bitcoin but not for investors. So even if one could guess the difficulty so good it wouldnt help much because if selling would be more profitable you need buyers that lose money. And there arent endless that doesnt matter if they will break even. Of course when one is after the fast money its another thing.
I believe here is a good guess: https://bitcointalk.org/index.php?topic=178051.0

I believe the question of how many devices to sell versus how many devices to mine with is essential to optimising profits.

Miners aren't necessarily insane just because they disagree on what the difficulty will be in the future. In theory, the amount a miner/investor is willing to pay is directly related to his/her expectations of future difficulty - and different people naturally have different expectations! Those with optimistic forecasts are willing to pay a higher price than those with pessimistic forecasts. If you sell devices to those with more optimistic forecasts compared to your own, you will make more money by selling it than you would expect to make by mining.

I think I might not have been clear in part - the exchange rate affects what people are willing to pay (in fiat) for the rig. We know this to be true watching BFL orders, which (presumably, based on order numbers) spiked considerably when the value of BTC went over $200. That's because they were buying based on current promised hashrate vs. expected difficulty vs. (then) current exchange rate. But you're correct in that it shouldn't matter at all when looking purely at BTC values... it's just that it's demonstrably NOT restricted to miners paying with BTC. Everything else I think we can agree on... just different pages from the same book Smiley

Interesting point - but also note that BFL has priced their machines in USD, so that when the exchange rate increases, so does the ROI: the price of BFL machines in terms of BTC actually decreased in that period, whereas the expected return in terms of BTC remained unchanged (more or less). If the machines are priced in BTC in the first place, it will probably develop differently since the ROI does not change.

Instead of throwing around percentages with little basis, I believe it is better to think in terms of net present value:

First step: make a forecast of difficulty.
Second step: make the choice: if (current price that a miner can be sold for) > (forecasted net present value of the mining profit from the miner), then SELL IT.

Of course, this relies on forecasting difficulty somewhat accurately. More importantly, if there are currently space/power limitations on deploying the miners, it is very likely that the choice of selling a large amount of miners immediately is the most profitable one.

With some more numbercrunching, one could also work with a probability distribution around the forecasted difficulty, and use portfolio theory to hit the risk/reward sweet spot.

Well, my point is that there's sure to be a perfect ratio that would generate maximum profit at any given point in time, and I'm pretty sure that, until all other ASIC manufacturers get up to speed, mining in the short term at much higher than 10% of global hashrate is better since difficulty is lower now than it will be in the future, and we seem to have a definitive leg up on the other manufacturers... but I have no idea what the optimal ratio actually is today, let alone in the future. It is, after all, a moving target... you're absolutely right that it depends entirely on total global hashrate (i.e. difficulty) and cost for devices per TH/s in the open market versus the going exchange rate for fiat. If BTC goes either up or down in value versus fiat, that will affect the optimal ratio of mining to selling by AM, as the prices people are willing to pay for devices, even in BTC, is affected by how valuable the BTC being generated are against their preferred fiat. If exchange rates are flat and hardware is not due for a generational update (as in changing the die size to a smaller process width), then it makes more sense to sell shovels. But, if we have a leg up in technology, it makes sense to keep that new technology (the "new shovels", so to speak) to ourselves until someone else comes out with a good competing product, while unloading the old shovels to the market. Only when there's a balance of power should we primarily focus on selling shovels, since the effect of our own addition to the hashrate would be balanced by the other manufacturers. Whenever we have the advantage, we displace our own in-house shovels with the new ones until it makes more sense to sell them, since our addition would have a greater effect on the difficulty levels and we would be the only ones able to take advantage. You are also very much correct when it comes to physical capacity, since we can't mine if there's no juice/space/cooling to run the machines. Smiley But I see that as an exception to the formula given the amount of space contracted recently.

I think this is mostly a time-to-market problem, really. The faster we can get the new shovels to market compared to the other ASIC manufacturers, the more we should hold back sales to be able to use them ourselves and to encourage the highest prices possible for the new shovels that we *do* sell. And, to circle around to my original point, if we commit to a certain percentage of the global hashrate, we have an advantage against the other manufacturers (on the basis of hardware sales) on two fronts: establishing market trust in the ability to deliver quality goods (we mine with our own shovels, after all) and stability in supply because everyone knows we're not only transparent about how many we're keeping for ourselves, but we're also depending on our development of new technology for our own mining efforts, meaning that we are going to push the envelope for our own good (which translates to the good of the buyers as well.) This is in the same general spirit as the Ferrari model, where if global demand for a car is 10,000 per year, they make 9,999 of them and command top dollar.

You may be right, but I think you are overthinking it. For instance, the BTC exchange rate is of little importance, since the choice is between mining and selling - both of which are paid in BTC.

After you have a difficulty forecast, you easily estimate many BTC a particular device will generate over its lifetime, for example, 50 BTC. Then say someone is willing to buy the device for 55 BTC. What do you do? Sell it, of course - you'll make more money!

And you can simply repeat this procedure for every device until the highest of the two values is below the marginal cost of producing the miner - at that point production is no longer profitable.

Of course some of the profit needs to go to R&D for next generation technology, but even then the basic principle remains the same. And you have to be good at forecasting difficulty and always keep the forecast up-to-date. And you need to know how much people are willing to pay for the devices. I assume AM has a difficulty forecast, and with the recent auction, AM has also learned more about what people are willing to pay for the devices.

PS: Even if your mining earnings estimate for the device is 50 BTC and someone is willing to buy it at 50 BTC, you should sell - because having 50 BTC in your wallet.dat today is much better than maybe having 50 BTC at some point in the future (because you eliminate uncertainty and you may re-invest it the 50 BTC from the sale).

With some more numbercrunching, one could also work with a probability distribution around the forecasted difficulty, and use portfolio theory to hit the risk/reward sweet spot.

I think a good way to get the best of both worlds is to commit to attempt to maintain a set percentage of the global hashrate, and sell the excess. (Say, 20%... I'm not really a fan of the 10% idea, that seems pretty low given the very small number of ASIC players that are publicly known, and by the end of the year, ASICs will control over 90% of the hashrate, if not sooner.) That way, shareholders have a predictable income stream from hashing, and purchasers of devices would know that their devices aren't going to be undercut by AM in any unknown way... pricing of devices would be stabilized (good for purchasers, which should increase demand for devices with better known values of return versus the competition with unknown levels of self-mining), and the only real cause of an individual miner's profit rate decline would then be the global hashrate growth, same as it has been historically.

If the AM share of global hashrate approaches 25%, priority shifts to sales to get it down to 20% for the benefit of device sales... if it goes to 15%, it shifts more to mining. (20% is just a number in my head, I'm sure there's a statistical sweet spot that someone can calculate... perhaps it really is 10%, I dunno.)

Why 25%? Why not 45% (To remain under 50% and the variance of networkhashrate around this). I think Asicminer now is in the best position of all producers. They can buy for low money many chips. Seeable from the lower dividends. Not much lost. They seems to have created a workflow that will lead to fast deployment. That means they can create new hashpower very fast. Probably faster than any other. Even Avalon with the selling of their Asicchips and the DIY-Miner wont be able to outbid this fast i believe.

So then, when reaching the 45% border, Asicminer could start to sell Miners. Maybe buy 1000TH, remain 750TH to hold the 45% and sell the rest in form of miners. Maybe more to take the customers from the other companies away (Mean, i know...) This way its possible to get the earnings of some months mining in a moment so that the real earnings are going above 50% without waking fear of the people about a >50% attack.

At the moment i dont see a company or concept that could beat Asicminer. At least from the infos available.
...
If only... the datacenter would be ready with proper power and network so that Asicminer could play out its power... Smiley

Sorry, but no.  You'll have to dig a little deeper than that.

Well then show me friedcat's posts predating March 12 mentioning plans to expand beyond 50 Thash/s (or beyond 12+50 Thash/s) or plans to sell hw -> There are none.

From friedcat's post from August 9, 2012:
Quote
If our chips are successfully produced, all the following businesses will
contribute to the shareholders' return:
  Self-Mining with First Batch of Chips At least 12TH/s in
total, that is equivalent to 30MH/s per share, or 300MH/s per BTC.
  Hashrate/Chip/Board Selling Net profits are
conservatively calculated as $5 per GH/s. That roughly equals to 0.5BTC per
GH/s with the current BTC/USD exchange rate. It means that each time we sell
1TH/s of hashing power in various forms, the net profit per share will be
1.25mBTC, that is, 1.25% of the initial investment.
  Self-Mining after Mass Production Unlimited hashrate in
theory because of the low margin cost. But in reality we have to consider the
cost of management (labor) and place (rent). We believe an expansion to 50TH/s
is not hard to achieve. That pushes the hashrate per share to 155MH/s, or
1.55G/s per BTC.
  Next-Generation Products The plan will be discussed among
board members and approved by shareholders, because it would require keeping
some of the revenues instead of paying them all as dividends. The return of
this stage is difficult to estimate, since in the Bitcoin world everything may
happen and happens even quicklier than imagination. But we personally believe
that much more potential profits wait there.

1@33

This is probably a dumb question... but where is ASICMINER located exactly and where will these be shipping from? As we see from Avalon batch 1, customs delay does matter a lot, especially since the expediency of these blades are their major selling point Tongue
China.

More specifically Hong Kong.

(And I know first-hand that parcels from Hong Kong often arrive to Europe quicker than inter-Europe parcels.)

Making a series of unrealistic assumptions here, but let's go:

They have 200TH+50TH+12TH coming in the near future. Put it all in 10 GH/s blades, and they have 26200 devices to sell. At 26 BTC a piece (current highest bid), that is 681200 BTC in total - or 1.703 BTC per share.

I know everyone knows, but to show that I am aware of it, here is how the assumptions are unrealistic:
1. Costs must be subtracted to go from revenue to profit
2. Not selling all TH/s (at the moment)
3. Price will decrease as difficulty increases

But in either case: this back-of-the-envelope calculation shows that the shares are still undervalued in my opinion.

And it also shows that it can be much, much more lucrative to sell miners rather than keeping them for self-mining.

If they all sell at 25, BTC250 spread across 400k shareholders is mBTC0.625 per share.

Last dividend was 0.00695566 (if you include the 1 satoshi per share), or mBTC6.95566

So, no idea what the profit margin on these things is - let's say it's 75% at this price (don't forget, shipping is included).

Which means the proceeds of this sale will produce a once-off 15% bump in dividends.

So the question now is - how many of these things do we have to sell, once the auction is over (and presumably the auction price will become the "normal" price).

Lol,
First auction is up. Tell your friends.

 https://bitcointalk.org/index.php?topic=178275.0


10.752 GH/s at current difficulty gives approx. 0.7 BTC/day. Those bids at 5 BTC are practically an insult!
Lol, you beat me to it. Absurdly low.

Well, it escalated quickly: up to 25 BTC now!

Auction - yes, definitely
Every item - not so sure.

Look, we are talking about ~200 TH/s. That's 660 000 chips per 300 MH/s. Part will be small units (1 chip) and part will be 21GH/s boards that are currently deployed.

Who will manage thousands and thousands week long auctions?

I think optimal way to determine price is to do 10 (20?) week-long auctions on first machines. And sell others with that price directly (without auction).

You think 200TH will be sold? I dont know if thats the case but i think that would be a huge mistake. Firstly it would bring so much TH into the net that asicminer mining revenue would drop dramatically. But the worst thing would be that selling 200TH would need very much money spent from the community. Think about it this way: A Avalon asic with 65GH only sold for $25000 on ebay. That means you would need to sell 3076 units with 65GH. For a total price of $76,923,077 or 1,025,641BTC (when 1BTC=$75). And i believe it wont be possible to sell so many units or Mining Power for a real good price.

So i think Asicminer wont sell so much. I might be wrong but i see a problem there. Leading to units selling way under the price they should get when less units were sold.

I would like to know how long it will take until Asicminer can resume deployment though. It cant be too long i hope. If that happens it wouldnt be necessary to sell very much TH anymore.

Auction seems like a good approach for price discovery. One would expect the price to approach the net present value of future mining profits of the most optimistic difficulty forecast. Assuming that price is achieved, it would actually be a considerably better deal to sell all the equipment rather than mining with them ourselves - especially if ASICMINERs expectations for difficulty are lower than the most optimistic forecasts of the mining community.

Then gradually as the most optimistic difficulty forecasts become more realistic, the price achieved in an auction will decrease - but ASICMINER can anyway keep selling until marginal cost, so there's a considerable profit to be made until that point.
274  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: April 04, 2013, 10:08:08 PM
The products are going to most likely be shipped from Hongkong. And what we accept is ordering instead of pre-ordering, which means that when we decide to sell, we ship it. Hopefully this makes our products be valued higher by the market.

I've heard great things about shipping out of Hong Kong: I've heard several people say that things ordered from Hong Kong have arrived at their destination in Europe quicker than ordering from a neighboring European country.

With BFL and Avalon increasing their prices, this could be a great success. Does anyone know, top of their head, the power consumption figures of BFL, Avalon and ASICMINER?

The price is going down here

this is because some of the investors are short-sighten in my opinion. They can only see the projected lowering in dividends and can't think long-term enough to wait for deployment of the 50 Thash/s batch

I think exactly the same. The rumours spread that now its not only half the dividend but maybe even a fourth only because of kept investment money is probably the reason for this. Plus the long lasting 6TH/s isnt advantageous. So i expected a drop. But im astonished how low it fell. I think that will go up soon again. At least in 8 days, when the next real dividend is paid.

A quick back-of-the-envelope valuation: imagine they reach the goal of 10% of the network hashing power, meaning 360 BTC/day, then annualise it and apply a P/E ratio of, say, 10, and you should end up at 3.285 BTC/share.

So it appears slightly undervalued in the market today... (or people in general don't believe ASICMINER can keep 10% of total hashing power)
277  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: March 26, 2013, 04:37:30 PM
It is actully very simple.
The unsold IPO shares are considered void until needed for fundraising.

Until then: sold IPO shares are treated as if they represent 200.000 shares.
If bitcoin does 8 decimals so can Asicminer-shares.

Therefore if 163,962 have been sold they are now valued at
1,21979483 times the dividend of a Bitfountain share.


Indeed, it is simple. But you still get it wrong: each ASICMINER share is entitled to 1/400 000 of the profit from this venture. No special provisions for sold/unsold shares.
278  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: March 26, 2013, 01:51:26 PM
That doesn't answer what is happening to those unsold 40k shares. Do they even exist? How is dividend calculated?

They exist. They belong to the founders. They receive dividends, in the same manner as the rest of the 400 000 shares.

Someone knows where the 15TH/s comes from that are added in the last days? http://blockchain.info/de/charts/hash-rate
Avalon?

Personally, I suspect it's BFL mining with their customers gear. I mean, do you really think they could resist that temptation? Especially when their actions don't appear to have any consequences whatsoever?

I really don;t think they have a working ASIC yet... especially considering their actions up till now  Wink

Conceded!

However, imagine if they have, for example, overestimated the power efficiency of the chips (I consider this very likely): sending them to customers would create desperate cries of scamming ("Chips do not meet spec!!!!"), but mining with them is still outrageously profitable.

Anyway, they haven't made an official statement for about 10 days, when they claimed they were testing the chips. But one thing I think can be agreed: either they are less competent than they initially claimed to be, or they are intentionally misleading their customers. Pick whichever theory you prefer, it still doesn't make them look very good.

But it makes ASICMINER look that much better!
