    How does Australian Customs treat imported goods paid in bitcoins (for the purposes of duty and GST)? ;)

      Thats a good question but I guess they will convert the btc value to the aud and tax.

    • Trance N Dance on 01/02/2014 - 21:56

      Australian Customs will go off what's declared on the customs form. If they think that the value is wrong they'll do some digging and work it out.

      • xordis on 02/02/2014 - 00:05

        What they said.

        If the value declared on the customs form is sus, they will ignore it and work out what they think the item is worth.
        Can and will backfire if you try to do the dodgy.

        • captobvious on 02/02/2014 - 21:54

          Pretty sure Customs know the market value of bitcoin and can convert it. didn't they just bust a whole bunch of people in relation to silkroad?

    er.. can this beat a Tri cross fire R9 290X box? LOL :p

    • Trance N Dance on 01/02/2014 - 21:50

      In outright power, probably not. In terms of GH/s, IIRC yes.

      • jackau on 01/02/2014 - 21:55

        single 290X clocks 707Kh/s

        Judge by the fact that You get a powerful gaming rig at the same time.. i assume the 290X solution is better in the long run for the resell value :)

        the way bitcoin is, every coin made makes the next coin harder to make and take longer to make..

        if there is a price clash.. then all goes south.. lucky the fiat money printing isnt going to stop any time soon

        • Trance N Dance on 01/02/2014 - 21:59

          The electricity price would put a huge dent into the profits though… Pushed to the max they'll draw ~300W each ontop of the draw from the other components and any inefficiency from the PSU. So with 3 290X you're looking at close to 3x the power draw from the wall compared to this machine.

        • Associateddreamzz @ eBay US on 01/02/2014 - 22:08

          290x will hash above 900Khs to 1000khs, draws 450W+,
          290 will hash 885Khs+ draws 300-350W
          280x will hash 720Khs+ draws 200-250W
          These are from my rigs, I also make rigs and sell for people. I charge a dollar per each Khs on the machines I make, example 6Mhs machine cost 6K, 5Mhs machine cost 5K etc.
          The best card to do a rig is 280x, that will give you the best return in terms of power usage and initial cost.
          Anyway this ANTMINER is only for bitcoin, not for scrypt so no point comparing both of them here, people dont use gpu's anymore to mine BTC.
          I am always in contact with new asic development companies so will get uptodate information and discounts.

          Depends whether you need the room heating.

          All computer power ends up as low grade heat. Just like the power that goes through an electric heater.

          In winter, if you would otherwise be using a continuous 0.5 kW of electric heat, then this does that… and does some crazy imaginary money fiddling on the side.

          Not saying it's a good idea… I guess I'm more saying that using an electric heater to generate low-grade heat with no other benefit is a bad idea.

      This is for sha-256 mining(bitcoin), gpu cards use for scrypt mining, so it cant compare with gpu. but a gpu rig will take 100days minimum to payoff, this one will give you an ROI within 30days.

      Dont look on online calculators as they are not correct, my knc jupiter (675ghs) makes 0.176btc a day, so do the maths, the antminer will mine 0.0473btc a day which makes it 1.419btc in 30days plus the profit of how long you run it and when you sell the miner.

    • tumor on 03/02/2014 - 11:24

      Take into consideration bitcoin difficulty DOUBLES just about every month.
      SO After one month, your output halves and so on…

      These things RARELY pay themselves off within a year, even if you can keep 99.9% up time.

      it is calculation power of the processor as value. Thats not exactly nothing given loads of fossil fuel / nuclear power is burnt for the power to power the computers. IN a way, it has solid value, more so than restless fiat money printing lead by world police. :)

        If you get electricity for free. Based on the 360w specified, it will cost about $80/mth to power @ 30c kWh.
        Also, bitcoins get harder to mine with time, so after a small number of months this will find fewer and fewer coins.

      • tumor on 03/02/2014 - 11:31
        +3

        Bitcoin difficulty doubles near every month, so your output will halve every month.

        Take into consideration it may take a month to get it going too, so your first month might make 0.5btc, then 0.25btc the next month.

        Unless you can buy in bulk and get the product delivered ON TIME, these things are very poor ways to make btc. Research Butterfly labs for more info on the ASIC scam, you're better off just buying BTC with your cash and sitting on it.

    "Original Price is 1.45BTC but I am organizing a group buy and made a deal with bitmine, thats close to 0.1btc discount which makes it the final price is 1.35btc, thats only if we can get enough numbers"

    Not appropriate for here. No 'active' price, it's trying to organise a group buy discount. Better in the forums.

    • jackau on 01/02/2014 - 22:10

    Why would you sell the technique of picking winning horses every time instead of taking the winnings yourself?

    Why would you sell a Bitcoin miner that makes profit after one month instead of taking the profits yourself?

    I apologise for being pessimistic, however I can't for the life of me understand why this is anything different than the first two questions in this post…

        How? If ROI is 30 days on this machine, the manufacturer can just use the machine for a month and earn the machine's worth while keeping the machine as well.

          Simple answer is if you dont knw bitcoin or dont believe in crypto currencies this is not for you. I cant answer all this questions, do google and find yourself.

          I didn't mean to be rude and demand answers from you. I see your post as a win-win for those who are willing to invest in Bitcoin mining and a positive contribution to the forum. I just couldn't understand the ROI figures and thought you'd have a better explanation.

          In this instance, what people question is not the about the nature about the cybercurrency, but the purchase price vs high ROI (regardless of the currency).

          Leaving behind Bitcoin, if a machine sells for $1500 and if it can make $1500 a month, one wonders why the owner would sell that machine in the first place.

        • Associateddreamzz @ eBay US on 01/02/2014 - 23:24

          I have answered it already as the manufactures makes more money buy selling, thats their business model. The figures I quoted is from my miner, so thats true, not from any online calculators those are completely our all the time.

          "if a machine sells for $1500 and if it can make $1500 a month, one wonders why the owner would sell that machine in the first place."

          Let's say the manufacturer builds the machine for $200, and that is the cost price for one of these machines. If the manufacturer keeps the machine to make bitcoins, then they don't make $1300 profit on one of these machines by selling them to you (assuming that they sell them for $1500 each). Instead they've spent $200 of their own dollars to make this machine, and once they've used them for a month to make $1500 and get back their profit, these machines are no longer worth $1500. Besides, their business is making these machines, not waste time setting them up and finding space for them etc.

          Do you guys get it now?

          Did you read your own post? What you wrote doesn't make any sense.

          If they build this machine for $200 they have two options:

          1) sell this machine for $1500 and profit $1300 in the first month, or
          2) keep the machine and profit $1300 in the first month plus they get to continue making $1500 every month going forward.

          Do you get this now?

          EDIT: below, Jinster offers the only feasible explanation as to why the machine makers would consider selling 'the goose that lays the golden egg'

        • chukkii on 03/02/2014 - 08:16

          I think the explaination is simple:

          I can make $1500 a month WORTH of bitcoins for each machine I make.

          Eventually I will make so many bitcoins I have to either sell each one at a lower price because of the sheer quantity I have, or I can just sell the machine and let someone else worry about finding buyers.

          I assume that this is the reason they'd make more money from building machines and accept less risk in the BTC market

        • cheng2008 on 03/02/2014 - 13:17

          "2) keep the machine and profit $1300 in the first month plus they get to continue making $1500 every month going forward."

          But that's the thing, that scenario will never happen. Putting aside the fact that there is no guarantee that they will make $1500 in the first month (the only person that said this might happen is the OP, and even he's not 100% sure) but bitcoins are designed to be harder to mine as time goes on. Someone here quoted a difficulty increase of 9% every 2 weeks, someone else quoted a doubling every month. I don't have enough experience to say who's closer, but even the real figures can change depending on how many people enter the mining business.

          In the end, it all boils down to this: no one will make $1500 a month with this thing past the first month. As the difficulty rises exponentially, the amount you can make drops quickly, and these machines become outdated and less valuable.

    • Jinster on 02/02/2014 - 00:07

      By selling the miner instead of mining, the manufacturer gets paid in real world money (or btc in this case, but they can quickly convert it to real money straight away), and real money with real economic backing (go buy stuff in US with USD, go buy stuff in AU with AUD - it's inconceivable US or AU would reject their own currencies) is always safer than a new "digital currency". Accepting digital coins is a choice made by the acceptor of the "coins". This choice can easily change. By contrast, the Australian nation cannot just choose to stop accepting Australian Dollars.

      So the seller of the miners are interested in securing profit in real world dollars.

      The buyer takes a punt that digital currency will increase in price, or at least hold the current price. This belief is quite irrational, but as long as everyone believes in it, this belief will continue to transmit, and thus become self-fulfilling. Much like how the stock-market works, despite brokers and investment advisers trying to justify their professional worth otherwise.

      It's all risk for the buyer, and little risk for the seller. Especially when these machines are usually pre-sold, i.e: they take your money, and then go make the machine. Search the internet for delays on delivery, and you will see this pattern.

      If they made the machines, and used them to mine coins instead of selling them, the value of coins could crash before they can profit. They rather not take this risk.

      Remember, in a good stock-market, both the brokers and the trader appear to get rich. When the market crashes, the brokers are the ones keeping their real profit. The trader's "paper profit" is lost.

      All I can say is, tulip bulbs.

      • ozgriff on 02/02/2014 - 10:09

        You're saying this:
        "the manufacturer gets paid in real world money (or btc in this case, but they can quickly convert it to real money straight away)"

        So the question is still quite valid, if in a short time you can create the cost of the machine from the machine itself; and this equals creating 'real world' money. Than why would you sell your money tree?

        • Jinster on 02/02/2014 - 12:04
          +4

          Fact: They do sell the machines instead of using them.

          Fact: People do buy them and manage to turn a profit.

          Fact: Profiting by selling machines in bulk via pre-order is a lot less risky than trying to turn a profit with the machines post-order.

          Fact: You can't both keep the machines to mine the coin AND sell the machine to the risk takers.

          Therefore, they choose to sell the machines, make less profit in the process, but the profit is certain, and relatively risk free.

          You are trying to paint a paradox of deception or illogic, but there isn't one. The seller is more risk adverse. The buyer is more risk tolerant. Thus the different behaviours.

          Examples of this are everywhere and shouldn't be surprising to you. This is the same reason why shipbuilders don't enter the fishing business, even though the purchase of a fishing ship will usually eventually result in profit for the fishing business operator. You can think of other examples yourself.

          In terms of the "short time" you mentioned, there is a HUGE difference between the 1min it takes to convert the prepayment of bitcoin into real world money when you order this machine, and the >1month it will take you to recover that amount by mining. The value of bitcoin is unlikely to drop in 1min, but could easily do so over 1 month. Again, less risk for the seller of the machines than the miners.

          Errr….

          An investment is NOT an investment… bitcoins are more commodity driven by sentiment than an actual currency.

          Recall the tulip bulb craze.

          My personal suggestion is, don't fall for this. If you have the ability to create the machines, go for it. Otherwise, stay away and look on. One day, the house of cards will fall, and it's not possible to predict which day.

          The real demand behind bitcoins, is shady operators on Silk Road selling drugs and doing money laundry. So there is demand for it. But surely you can see how this can potentially all fall apart once law enforcement and legislators get involved.

          You cannot possibly outlaw USD, in which millions of people are being paid. But a digital currency with no real world backing? Phew…. watch for the puff.

        • ozgriff on 02/02/2014 - 13:08

          ok, last comment of mine and leaving it to the birds.

          Shipbuilder analogy is not really the same, as a ship builder will no longer be able to build ships (their primary business) if off fishing in the boats, plus the man hours and skill-sets required to become both a successful fisherman and boat-builder are quite extreme. The large capital required and length of time to re-capture it is also significantly larger.

          This is a plug and leave machine requiring little human resources or skills (I believe, but not 100% sure how it all works) that will repay itself in 4 weeks, a very quick turnaround.

          I'd imagine this to be a closer analogy of solar farming, where if a solar panel could pay for itself in 30 days, why would the manufacturers not keep them and re-invest in the very quick profit, until they have large solar farms paying for themselves and creating MASSIVE profit thereafter. That's the analogy that makes this seem more of a stay clear of scheme, promising quick riches (always too good to be true).

          Trust me, I'm leaving it well alone myself. Happy for others to make the investment in capital and other resources for their mining (we'll agree to disagree over the an investment is NOT an investment) as this venture is not over sentiment but profit.

          I believe silk road has already been shut down by the US authorities and that bit-coins themselves are being closely observed by all and sundry in the legal, financial and trading sectors.

          As someone who has been looking at cryptocurrencies for over a year now, I think there is has been a lot of oversimplification in this thread.

          There are several reasons why manufacturers do not use the miners themselves, some of the reasons are:
          1. The vast majority use a "pre-order" based model where they generate capital for design and fabrication using miner pre-orders. There is a fair bit of trust involved and invariably there are reputations of "guarantors" at stake (big respectable names like bobsag3 are involved). Screwing customers over will cause a tremendous backlash (see BFL).

          1. Mining using their own rigs by the manufacturer will result in the difficulty going up dramatically thereby reducing confidence in mining hardware and hurting the hardware market hugely. Also these rigs are not magical "money machines". There is a fair bit of supporting infrastructure required (e.g. cooling, power, UPS etc). Moreover, the operator needs a bit of technical expertise to operate (e.g. Bitfury boards require the raspberry pi as a controller and a proper setup using cgminer).

          2. There will be a massive impact to the "trust" people have on bitcoin if the computational power owner by a miner approaches 51%. See concerns raised about the DOGECOIN mining pool called dogehouse which is approaching 51% of the computational power of the entire network.

          There are many more reasons which boil down to one basic thing, unscrupulous acts impact the confidence that people have on the cryptocurrency and consequently the value of the currency.

          PS: Silk road is down, but there are heaps more that have sprung up in its place. It's like the mythical hydra. :)

          Thanks for the awesome post, clears up a bit of the mystery, whereas I was thinking it was more down to computational power.

      The more people buy mining hardware the higher the difficulty goes. It's quite possible to buy hardware that never generates more bitcoins than it cost to purchase because so many other miners are jumping in too. By selling the hardware direct the company makes a guaranteed profit: everyone else is counting on not too many people mining before the cost of electricity outweighs the value of the bitcoins generated.

      This has already happened with CPU based mining, then GPU, then FPGA, and now the less efficient ASIC miners are barely returning more money than they cost to run. Expect this to continue.

      The OP states return on investment can be achieved within 30 days. I would triple that estimate without any hesitation, and prepare to wait longer still.

    "In the beginning, CPUs were good enough for mining. Then came GPUs, but CPUs could also be used. Then came FPGAs as CPUs stopped being profitable. Then ASICs came in, with GPUs becoming less profitable. It is only a matter of time for a newer type of miner to be developed, a much faster and cheaper miner, for it to be profitable. Or of course, if Bitcoin’s price went through the roof, or if ASIC prices lowers dramatically."

    From this, I'd hazard a guess that one has to be quick to reap benefits from bitcoin mining (eg. buy a dedicated machine like this) and the rate of new profits will diminish exponentially.

  • plasmoske on 01/02/2014 - 23:36

    Not profitable. If you spend bitcoins on a miner that mines bitcoins, and it makes back less bitcoins than what you've spent, then you're actually losing money.

      bitcoin mining is required for bitcoin to work (creating the public ledger for everyone's security) and it is how the new money is slowly introduced (like gold mining). Because of this, bitcoin mining can't be "not profitable", otherwise after a while people will realise and won't do it then. Am I missing something?

    • Tnetennba on 02/02/2014 - 00:12

      Seeing as bitcoin mining has become a LOT harder since the massive surge in popularity (a gimmick imo but that's another story), it is quite hard to actually have it break even. Add in crappy australian power prices, fees that you will inevitably face when converting BTC > AUD, etc, and you could end up in a world of frustration.

      I'm not saying it's not doable, but it's a very risky investment in my opinion, I wouldn't put $1500 into this.

    How much electricity will this use per day KWh? Will this have to be turned on 24/7?

      360 W/hr / 1000W/kW * 24h/day * 30day/mo = 259.2kWh/mo

      An average energy cost is about $0.30/kWh = $77.76/mo

    Beware the difficulty 2,193,847,870 which is went up ALOTs since the last time i check it ( oct last year ). There are sites let's you calculate the outcome base on GHz, difficulty ect …

    PS: Only 90days for $1500 investment that run 24/7 … i think you get 1-2yrs for your fridge …

    I'm in, but at 180GHs it's still pointless, you would be making ~$40/Day and once all these new 20nm and (28nm BFL) products are released this profit margin will drop again as the diff will rise.

      Then buy more like what i do 20 :) . it doesnt matter how many you ordered, you will get the same ratio of profit of your investment. From my calculation its 30days ROI is guaranteed. Dont looks at any online calculators, if you have a friend who has a miner, take the actual values from it and do your maths.

  • garamb0z on 02/02/2014 - 11:43

    When will you place an order? I need time to grab btc. Anyone here selling btc?

      I need a bit coin miner to solve this. But to get such an item requires a phone number. But your phone number is encrypted. I don't like this loop.

  • foxxo on 02/02/2014 - 13:53

    By my calculations, breakeven after 77 days not including electricity. That's taking into account a 9% difficulty increase every 2 weeks and appreciation in BTC by 2% per week. After 30 weeks (203 days) you have around $3357. So a good part of a year to double your money.

    • plasmoske on 03/02/2014 - 22:47

      9% every 2 weeks? Wow that's super low!

      Average is about 25% to 50% these days.

  • surm on 02/02/2014 - 14:38

    How do hosted/cloud mining services compare against these?

    eg.
    https://cex.io/about

    Miners don't have to invest in hardware. Instead, they rent it and start mining immediately. Miners can add (rent) more power as the difficulty increases. Sounds more scalable and less risky for end users.

      Check the rates, way higher, If you want to hosted I can do it way cheaper. :)

    If your serious about bitcoin mining… there is only 1 company making decent rigs.

    https://www.kncminer.com/products/neptune-second-batch

    Forget the rest…

    3 Terahashes as a minimum! … for $10000….

    Better value and guaranteed return with today's difficulty.
