Specifically, you’ll need cheaper electricity and better access to the latest mining hardware. On top of that, the mining game got even tougher following the second halving event, which reduced the reward for successfully mining a block from 25 bitcoins down to 12. 200 after the 2nd halving in early July. Electricity costs will depend on your location and situation. Where Milli can help is by recommending the best available ASIC miners but first, we’ll need to explain a few technical mining terms. Bitcoin Mining Hardware Jargon Hashrate: the measure of how many attempts at solving a Bitcoin block a miner attempts per second. Obviously, the more attempts the greater the chance of solving the block and claiming the 12.

Joule per Gigahash:  A Joule is a measure of energy, representing 1 watt over 1 second. The fewer Joules used to produce a Gigahash, the higher an ASIC miner’s electrical efficiency. Difficulty: with hashrate ramping up since Bitcoin’s release, one could be forgiven for expecting that blocks would be solved increasingly quickly. Difficulty is an automatic control measure which prevents that from occurring. This ever-adjusting Difficulty mechanism, combined with Bitcoin’s volatile price, make calculating the future profitability of Bitcoin mining very tricky!

99Bitcoins’ mining profitability calculator is good for this purpose but if you’re serious about getting into mining, it’s recommended that you create a custom spreadsheet with inputs reflective of various exchange rate and Difficulty projections. Remember to account for probable downtime due to power cuts, hardware or software failures and the like. Break-even point is the length of time it takes for your miner to pay for itself, if it ever does. Mining pools are cooperative groups which combine their hash-power and distribute any rewards which the pool earns proportional to individual hashrates.

Although the S9 is four or five times more expensive than its rivals, it also mines about three to four times more bitcoins and also uses electricity far more efficiently. If your intention is to mine for profit at a small scale, at this stage the S9 represents your best shot at success.

If you’re not out for profit and you’d rather mine for hobby or experimentation purposes then the S9’s hefty price tag is hard to justify. Bitmain is currently the leading manufacturer of publically-available ASIC hardware. In layman’s terms, this means that the circuits in the S9’s BM1387 chips are nearly half the size of previous generation mining chips. While other companies are developing 14nm chips, smaller fabrication processes are costly and time-consuming to establish. This means that the rate of advancement in Bitcoin mining hardware, remarkable for its speed and for being funded without major corporate involvement, will inevitably slow in the years ahead until the limits of current semi-conductor technology are reached. Nonetheless, it’s highly unlikely that break-even will be reached in less than a year as the overly-optimistic calculator suggests. However, with cheap enough electricity, the S9 should eventually pay for itself.

Difficulty should be expected to rise. Note that the S9’s performance varies considerably according to production batches. As the power consumption of new models is also lower, efficiency remains similar. The S9 will run on a standard PSU but Antminer’s 1600W APW3-12-1600-B2 is often recommended. In fact, it’s so popular that you’ll struggle to find a good used unit at a price cheaper than new! Of course, it can still be worthwhile to buy an S7 second-hand if it’s available locally, to save on shipping time and costs. 28nm process, although it can be improved further through skilled modification.

The S7 also has a more affordable price tag than the S9, making it an easy introduction model for prospective miners. The S7 is also available as a variant model, the S7-LN model, featuring a built-in 700W power supply. Less power means fewer hashes and the LN only achieves 2. 291 plus less heat and noise. The LN is good for home or office use, although you’d probably want it behind a closed door. Note that the weight of the attached PSU adds considerably to shipping costs.

The Underdog: Canaan’s Avalon6 Given Bitcoin’s decentralized ideals, many are unhappy with Bitmain’s dominance of the hardware market. The Avalon6 from Canaan Creative is probably the best option. Although it doesn’t offer quite as much bang for the buck as an S7, it’s still a very good 28nm miner. The Avalon6 achieves a slightly lower hashrate and efficiency but uses about 300W less power.

A smaller and cheaper PSU can be used. Offsetting any PSU saving is the fact that the Avalon6 doesn’t with an inbuilt controller. Forthcoming Attractions This article describes the current state of play but new technology gets released all the time. A section and I’ll do my best to respond within 24 hours. KnCMiner says it has finalized the design of what should be the world’s first 20nm bitcoin ASIC miner. The company is still not saying much about the upcoming ASIC or the rollout schedule, it merely states that the ‘tape-out’ was achieved only three months after starting the project.

The actual tape-out happened sometime in February. In electronics, a tape-out is the last stage of the design cycle for an integrated circuit. This sounds like a realistic estimate, as we have been hearing similar claims from chipmakers who are planning to transition from 28nm to 20nm later this year. In addition to the new node, KnC has also optimised the design of on-die circuitry, which allowed it to stick 1440 cores in a relatively big 55 x 55mm package. Back in November KnC said the Neptune 20nm chip would deliver at least 3TH of power, operating at 0.

This would not be the first time. However, it will be a while before we know whether Neptune can over-deliver like its predecessor. Tricky transition Marcus Erlandson, KnC’s CTO said he is proud of the team’s performance. The combined efforts of KnC and our partners Alchip means that once again we are bringing to market a world first silicon design and in record time,” he said. President of Alchip Johnny Shen said KnC and Alchip have been working together on bitcoin ASIC design for less than a year and they have already delivered “two world-first projects”. It is still unclear when the new ASIC will be ready for production.
