Bitmain Antminer S9 Evaluate
Difficulty has nearly tripled since then, climbing from520,569,941GH/s to the current document high of 1,426,731,353 GH/s.
This peak was reached on Might twenty fourth 2016. Such great progress has been spurred by major investment into Bitcoin mining technology and operations.
While such growth is impressive, making Bitcoin the world’s strongest computing network by far, one unintended consequence of such speedy progress has been increased centralisation.
Profits have gathered where mining is most profitable (China), with the outcome that several competing operations (eg. KNC) have been forced out the industry.
The same Chinese competitive advantage has been doubly effective at squeezing the profit-dependent hobbyist miner from the market.
At this stage, most home or office miners aren’t hashing to earn money however rather to support the network, aid decentralisation and possibly even to heat space.
With the block reward halving looming, the profitability of all but essentially the most environment friendly operations will probably be challenged.
Given that profits derived from the present generation of mining hardware are dwindling and can doubtless attain negative returns put up-halving:
Can the new S9 change the game for smaller and pastime miners and restore their lost profitability?
The primary batch of S9s can be available for order directly from Bitmain from the 12th of June.
At $2100 on Amazon, the S9 is way from cheap. Nonetheless, the lower your electrical energy costs, the higher your odds of the miner paying for itself within a reasonable timeframe.
Naturally, much depends on the Issue and Bitcoin price.
As smaller manufacturing processes turn out to be customary across the industry and as different producers launch competing hardware, the S9’s worth might be expected to fall appreciably over the approaching months.
Bi Wang is launching its 14nm chips sometime in winter 2016 and BitFury’s own 16nm architecture hardware, promising unbelievable power effectivity at 0.06 J/GH, can be reported to be coming soon.
Judging value in this area is a sophisticated train, though it might appear that nothing vastly technologically-superior to the S9 is likely to be released in the close to future.
The release cycle of a new generation of mining hardware every few months is likely to decelerate from this level on, as producers have transitioned to cutting-edge sixteen and 14nm designs.
The S9’s sixteen Nanometer Technological Advantage
The on-going miniaturisation of semiconductors permits ever higher computing energy and electrical efficiency, but the process can not continue forever with the current technology.
Many have remarked that Moore’s law not holds true, as the rate of computing speed advancement has slowed as it reaches the physical limitations of silicon semiconductor technology.
The 16 nm fabrication process used in the manufacture of the S9 is a significant improvement upon the 28 nm design frequent to different fashionable mining devices.
Though a 10nm process is on the horizon for 2017, additional increases beyond that remain theoretical.
Further, the design and manufacture of any 10nm Bitcoin mining hardware is prone to take at the least a year.
Bitcoins / Month (Profitability)
The S9 has more hashing power than any previous machine crammed into its silicon; a massive 14 TH/s (TeraHash per second).
A total of 189 chips, spread over three circuit boards, are mixed to achieve this phenomenal hashrate.
Excluding a 15 temporary TH/s spike which occurred late 2011, a single S9 unit boasts a hashrate equivalent to the height capability of the whole Bitcoin network from its bootstrapping until mid-2012!
Let’s calculate the projected profits from all that hashpower by way of our Bitcoin mining calculator :
Note that Power Cost can be particular to your location and that Problem adjustments every 2 weeks, normally to the upside…
Though preserve in mind that put up-halving, it’s entirely potential that a variety of marginal miners can be compelled to both upgrade to higher hardware or shut down.
Your Pool Fees can be determined by your mining pool; though the S9 is a lot powerful, a single unit is highly unlikely to search out any blocks when solo-mining.
Finally, the Bitcoin to Dollar (USD) price is infamous for its constant state of flux.
Based on the above inputs, the S9 will produce** 0.285 BTC / $159 per month** and 3.36 BTC / $1939 per year.
These puts Return on Investment (ROI) slightly above one 12 months!
After all, such spectacular results assume all factors stay constant which is hugely improbable within the ever-changing world of Bitcoin!
