Another cool idea would be to sell excess bandwidth over the internet, rather than over wifi. So if i have 100gb of spare internet quota with X ISP, and you need extra internet quota, then i sell you my spare quota for bitcoins. Not sure if its technically possible tho
o.O

You'd still have to use internet quota in order to use the spare internet quota.  It wouldn't work.

4164  Bitcoin / Bitcoin Discussion / Re: Send 0.01 BTC without a fee? on: May 31, 2012, 04:36:58 AM
Is it possible to send someone a bitcent without a fee?  How old would the coins have to be in order to do so?

To avoid fees, the coins you spend should be at least 1 "bitcoin day" old.  A 3 BTC input that is 4 days old is 12 "bitcoin days" old.  Like "man hours" - 3 men working for 4 hours each is 12 man hours.

So to send 1/100th of a bitcoin for free, it needs to be 100 days old.

To send 24 bitcoins for free, they need to be 1 hour old.

Etc.

If any of your outputs are less than 0.01 BTC (including any change output), then you will always need to include a fee.

This is to avoid the recommended fee, of course.  If you edit the source you can send any amount you like without a fee, but miners may then decide not to include your transaction in a block.

Edit: if you have a 1 BTC coin that is 1 day old, you will be able to send 0.01 BTC (with 0.99 BTC change) without paying a fee.  It's the size and age of the inputs that matters, not the outputs.  Though the outputs have to be a bit cent or more to avoid fees.

Edit2: and it's not really the age that matters, but the number of confirmations.  If we get 1 block every 10 minutes then the above is true.
I just realized though... in order to make it work, one would have to "pre-send" a whole bunch of 0.01 BTC amounts to different addresses.  That way, the coinage not sent remains old.  If I were to just send 0.01 out of 1 BTC, then suddenly, the other 0.99 BTC is brand new again, and cannot be sent fee-less for a while afterward.

Thanks for the input Blazr - I was looking for more of a technical response about when a fee is required/not required, but it's good to know that even though the fee is "required", it still eventually gets pushed through.
4165  Bitcoin / Bitcoin Discussion / Re: Send 0.01 BTC without a fee? on: May 31, 2012, 02:04:20 AM
Its possible, but it won't always get confirmed.

I only send a 1 satoshi tx fee for all of my transactions (regardless of size), and I've yet to get one that didn't confirm. I did have a few that took a few hours to get 1 confirm though.

There are miners out there that will accept transactions that haven't paid the minimum tx fee.

Are you sending the tx direct to pools?
Mainly, I was curious if a site that gives away free small amounts of BTC could potentially send those amounts as soon as they are requested instead of waiting to send them all in one big batch.
4166  Bitcoin / Hardware / Re: BitForce SC - full custom ASIC on: May 31, 2012, 01:00:15 AM
I have a question.  Suppose the network hashing speed climbed to something like 120 TH/s and ASIC miners made up 90% of it.  Would an algo change by the Bitcoin developers be subject to acceptance by more than 50% of the network before it could take place?
No.

5% of the network could accept it and continue on.  They'd just be on a different blockchain than everyone else.

Why would you want to change the algo just because ASICs came into play though?  Doing so would be admitting that Bitcoin logic is faulty, that it can never grow large enough to warrant support from investment into ASIC mining, and would ultimately destroy confidence in Bitcoin itself.

896 seems to be beyond the limit for most chips already.

TWO chips.
Quite likely, with TWO completely unrolled, pipelined miners on each of them.
Or a "sea of miners" on them, as brilliantly demonstrated by Bitfury on the Spartan6 platform.

Huh?  It was beyond the limit for 3 of mine already.

I was just trying to point out that the 896 MH/s are spread out over TWO FPGAs, not just one.
Maybe you meant to say "beyond the limit for most Singles".
Ahhh, yes indeed.  Beyond the limit for most Singles.

Of course, I want to have some extra money for my time and effort after it's all said and done.  So, if I am expecting $10,000 in revenue, the maximum I would be willing to pay might be around $7,500.

Your turn.

Excellent, your order will be shipped in 4-6 weeks. Your order number is #101.  
Yes we already sold 100 units this month (80 to gigavps who will receive them tomorrow). We will auction off 100 more units on ebay every month, these chips cost $10 to produce, so why not.

Care to redo your math?
Then I just got burned because I didn't do due diligence research on finding out how many others of these ASICs were produced.

However, I understand your point.  The concern is that ASIC mining will increase difficulty so vastly and so quickly, that miners will not be able to accurately formulate a proper ROI estimate, even if being conservative, and overestimate what they will actually be able to produce.

Certainly, you've exaggerated the scale with 100 GH/s @ 1w, but the electric usage will still be nearly negligible compared to the initial outlay for the units.

I think more accurate calculations and assumptions can be made when BFL makes their announcement.  Some people will be willing to take the risk, and others will not.  If they release 1 GH/s units, it would be much more difficult to increase the difficulty quickly compared to 100 GH/s units.  They'd have to ship 100x as many units that way.  So the GH/s per unit is an important factor, as well as the (guesstimated) price per unit, guesstimated production capacity, etc.

Thanks for letting us know.

Is there any point releasing higher speed firmwares ?

What is the theoretical maximum for these chips that can be used if you had subzero cooling for example ?
BFL seemed to indicate that they ran chips up to 1.05 GH/s.
They ran a simulation that said they could get 1.05 GH/s
Ahhh, much different from actually running a chip that fast!  Especially given the results of real-world testing of the 896 firmware, I doubt that we'll see anything much faster - 896 seems to be beyond the limit for most chips already.
4172  Bitcoin / Hardware / Re: BitForce SC - full custom ASIC on: May 30, 2012, 09:16:49 PM
Entropy - I get charged on my credit card all the time before a shipment is made.  The company I work for does the same.  I have never heard of it violating any sort of consumer protection laws.

@SgtSpike,
Clearly Im not getting my point across. Lets try a different approach.

Assume I have 28nm fab in my mothers basement and I just finished my asic miner. I put it up for sale, long before BFL; 100 GH, 1W, delivery in 3-6 weeks. You can order today.

Will you order one if I asked $100K ? $10K? $5K? $1K?
Ok, I'll bite.

At 100 GH/s with negligible electricity usage, I would stand to make nearly $10,000/month at current price/difficulty ratios.

Most reasonable people would expect a ROI of equal to or greater than the stock market (in this case, greater, since Bitcoin investments are still generally very risky).  I personally would like to see payback within 6 months, but would probably accept a payback of up to 1 year.

So, if the price is $60k, payback in 6 months, I would order.  If it is $70k=$120k, payback in 7 months, I might not.  If it is $120k+, I definitely would not.

Now, say I have the knowledge (or an educated guess) that you might drop the price from $60k to $10.  Ok, fine.  My payback period just got increased from 6 months to 3,000 years.  Whoops, should have seen that one coming.  It'll pay back, but not in my lifetime!

Ok, so the most I am willing to risk is a 6 month payback at current rates, but with the expectation that the price could drop to as low as $10, and a maximum of 3 years payback if it does.  If the price drops to $10 for 100 GH/s, I could expect 1.3 million of these boxes to be purchased, eventually, at the current price point of ~$5/BTC.  With 1.3 million, we'd have 131M GH/s, or 131.4 PH/s of network power.  The payback on these boxes would be 6 months at that price/difficulty ratio, so they'd be generating around $1.60/month worth of BTC.

Still, those 1.31 million boxes wouldn't be produced and sold in a day.  It would take months, perhaps years to get that many produced, packaged, sold, and shipped out.  I would be expecting this, and would maybe expect difficulty to double every 2 weeks at the most.  So, the first 2 weeks, I would make $5,000, the second two weeks, $2,500, third two weeks, $1,250, etc.  Basically, my revenue would virtually max out at just below $10,000 by the time my goal ROI of 6 months is up.  I'd still be making the $1.60/month extra, but that amount would be negligible compared to my initial investment.

Of course, I want to have some extra money for my time and effort after it's all said and done.  So, if I am expecting $10,000 in revenue, the maximum I would be willing to pay might be around $7,500.

Your turn.
4173  Bitcoin / Hardware / Re: BitForce SC - full custom ASIC on: May 30, 2012, 08:41:41 PM
Again, miners should do what makes the most financial sense to them.  They should be sure to calculate any expected price drops into their equation, and decide when the best point to purchase (if any) is.

And how will you know? You expect BFL to tell you how many chips they will sell in what period or at what (future) price? Without that information you can not make an informed decision.
Quote
What you are describing is ASIC miners being priced high to start with, then as time goes on and competition is introduced, the prices will drop to the equilibrium of supply and demand.  That is typical of any product.

No, you still dont get it. This is not typical at all. I cant honestly think of a market with similar dynamics.

Quote
BFL wants to maximize the revenue of the miners, because the miners are their customers.

Logical fallacy. You dont make a distinction between customers that already handed a check and have a miner thats yet to break even on its cost,  and potential new customers. The former ones want a low difficulty, and the only way to keep difficulty low is if those asics remain expensive/difficulty. The latter ones only want a good price/difficulty (which will increase difficulty). So you cant please both. It cant be both cheap and expensive for a given difficulty.  Now guess which type of customer BFL will care about most?

I won't know.  No one will.  That's why one must make an educated guess.  Your educated guess is different from my educated guess, and that is fine.  Overall though, the market will know when to stop buying ASICs because the ROI is too high for the risk involved.  Individually, some people will step over that line anyway, and take absolutely forever to pay off their miners.

The customer is one and the same.  If the projected ROI is not sufficient or quick enough to mitigate the risk of a price drop (and increased difficulty because of it), then the first miner shouldn't have bought in the first place.  If the projected ROI of the second miner (assuming price of ASIC miners has reached rock-bottom and isn't expected to move downward any further) isn't high enough as opposed to other investments they could be putting their money towards, then they won't invest anyway.

So, what's your point?  Are you just warning us to make smart decisions because future price drops will probably be coming?  If so, then I agree with you - that sort of thinking is smart and should be part of any miner's decision to purchase or not purchase miners.  If not, then what point are you trying to get across?

Fortunately for us, ensuring the continued success of Bitcoin is exactly what WILL maximize BFL's bottom line,
[...]
which means they should and will do everything in their power to maximize miners' revenue.

Sounds like someone is starting to make some sense around here.

Does that quote really make sense to you? If you truly think any ASIC providers' interest align completely with a miner's interests, and they will "do everything in their power to maximize miners revenue" rather than their own, then you are not the intelligent guy I took you for.

Well, I guess in a way they do have the same interest: their own bottom line.  But after the first asics will begin having an effect on difficulty, the asic provider and the miner will have diametrically opposed interests: one will want to keep selling as many as possible virtually free to produce chips to pay back his NRE, thereby constantly dropping prices to adjust for, and as  a result, increasing difficulty - potentially by orders of magnitude; while the miner would like to achieve an ROI on his investment, and wont be able to do so if difficulty goes up any faster than what he had planned for.

Ive asked the question before: what payback time would you look for to buy an ASIC? And what happens if BFL then sells ASICs twice as fast as you expected?

Quote
Pity all the naysayers don't just do their due diligence (I've said this multiple times and I'll keep saying it) and get to know the guys over at BFL. I have, and they are some pretty smart guys who believe in Bitcoin's potential.

I got no problems with BFL. The issue is not BFL, its with asics in general; it will be the same with any company that would enter this market first and effectively obtains a dial that can turn up difficulty at will and must turn this dial to make a profit. I can think of some ways they could mitigate the miner risk, but none that wouldnt collide with their own bottom line.
Again, miners should do what makes the most financial sense to them.  They should be sure to calculate any expected price drops into their equation, and decide when the best point to purchase (if any) is.

What you are describing is ASIC miners being priced high to start with, then as time goes on and competition is introduced, the prices will drop to the equilibrium of supply and demand.  That is typical of any product.  Any miner who does not take this price curve into account has only themselves to blame.

BFL wants to maximize the revenue of the miners, because the miners are their customers.  If they can increase the total revenue of miners, they increase their customer base and potential revenue.  That's why I keep saying they won't do anything that will harm the Bitcoin price, because that reduces their potential sales, as sales will be capped by the difficulty.

For some reason, you seem to assume that all miners are idiots, and won't take difficulty increases and price drops into account.  As the ROI is stretched to longer periods, you WILL see a decrease in the number of purchases, as no one wants to hold on to a risky, volatile asset for a length period of time in the hopes that it will pay off.  But BEFORE it reaches the point of being unable to return on the investment at all, people will stop buying them.

I hold to the position that, as long as BTC price doesn't drop significantly, ALL ASICs that are purchased will eventually pay back.  It might take a while, depending on the price point at which they are purchased and such, but the market can judge at what point the risk outweighs the potential revenue, and at what point the ROI is not worth the investment.

Angry neighborhood bastard mod, author of DiabloMiner, founder of Diablo Mining Company, and all around Demigod of the Bitcoin community here.

Hows this: BFL sends me the smallest ASIC product they make, I receive it, and then I will everyone that not only does it exist, but it works. This should end all the trolling, and if it doesn't I will happily start modding this forum until the shit ceases.

This should solve all the problems.

Nice try. lol

I'm quite serious. I'm tired of people attacking BFL for no reason, and I will just start discussing long term depopulation plans with Theymos if this continues. Its completely up to the trolls inhabiting this thread on what happens next.

BFL sending me a unit for inspection and testing would prove it exists and works and isn't vaporware.
You'll still have Mem around for calling them scammers even after they give 100 of us legitimate ASIC units.
4177  Bitcoin / Hardware / Re: BitForce SC - full custom ASIC on: May 30, 2012, 05:46:08 PM
If they end up selling ASIC units then these units will be priced at breakeven or a loss to miners over the next 12+ months simply because if anyone is capable of building ASIC units and mine with it in a profitable setup then it would be retarded to sell these units and lose out on your own market share where you could be earning more than selling it.
This.  Anyone that thinks BFL is out for anything other than pure profit is naively fooling themselves.  BFL doesn't care if bitcoin dies as long as it maximizes the bottom line.

Shame that BFL will be the first to market with an ASIC.  Couldn't happen to a shadier company.
Fortunately for us, ensuring the continued success of Bitcoin is exactly what WILL maximize BFL's bottom line, and they know that.  They wouldn't do anything that would harm confidence in Bitcoin or cause it to die.  BFL will only continue selling miners so long as mining is profitable, which means they should and will do everything in their power to maximize miners' revenue.

Cablepair - BFL already stated that $5000 was far too high a price point for one, and potentially two of their SC products.  They also stated that they wanted to make the ASIC miners available to "the average person".

Again, BFL doing ANYTHING to reduce confidence in Bitcoin would be essentially biting the hand that feeds them.  It would make no financial sense.  Yes, they are in it for the money, but the money comes in as long as Bitcoin remains a project that people are confident about.  I do not see how it would be advantageous for BFL to abuse the network for their own gain with the potential to undermine the Bitcoin project.  They would be far better served (and have even confirmed as much) to simply produce the products that people want, and sell them to those people.

From what BFL is saying, they WANT to see Bitcoin succeed, they WANT to put these ASICs in the hands of the everyday person, and they do NOT want to mine with them.  You can put on your tinfoil hat and say that they are lying and it's all one big coverup to bring down Bitcoin to the ashes, but I believe that BFL is a company with good intentions and smart leadership, and will not work to destroy Bitcoin, only to make it stronger. 

The best way for BFL to make a large profit is to increase confidence (and therefore price) of Bitcoin.  All these conspiracy theories about wealthy people banding together to maliciously attack the network just make absolutely no sense, and are not founded in any sort of reality I can imagine.
