Before you buy an Antminer S9 make sure you already have Bitcoin mining software and a Bitcoin mining pool. The first batch of S9s will be available for order directly from Bitmain from the 12 th of June. However, the lower your electricity costs, the better your odds of the miner paying for itself within a reasonable timeframe.
Judging value in this space is a complicated exercise, although it would appear that nothing vastly technologically-superior to the S9 is likely to be released in the near future. The release cycle of a new generation of mining antminer every few months is likely to decelerate from this point on, as manufacturers have transitioned to cutting-edge 16 and 14nm designs. The on-going miniaturisation of semiconductors allows ever greater computing power and electrical efficiency, but the process cannot continue forever with the current technology. The 16 nm gtx 1060 6gt ocv1 6gb process used in the manufacture of the S9 is a major improvement upon the 28 nm design common to other modern mining devices.
Although a 10nm process is on the horizon forfurther increases beyond that remain theoretical. Further, the design and manufacture of any 10nm Bitcoin mining hardware is likely to take at least a year.
The good news is that existing power supplies, at least those of sufficient wattage, are fully compatible with the S9. A total of chips, spread over 3 circuit boards, are combined to achieve this phenomenal hashrate. This is of course antminer revenue and not taking into account the electricity, mining pool fees, or hardware expenses. I ran the numbers against 3 different Bitcoin mining calculators and antminer bfgminer all show the same result.
The Antminer S9 is also the most efficient miner on the market. This means that it wastes the least amount of energy than all other miners out there. If you add into account electricity cost as well you will generate a little less than that antminer around 0.
antminer The price of the Antmier s9 varies a lot. This is the most expensive miner on the market today because its superior mining abilities. If you own a PSU of an old Bitcoin miner you might be able to use that as well. Seeing as most people will probably rush to buy the new Antminer s9 you may want to consider getting the older model Antminer s7 at a discounted price due to lower demand. My overall rating is a antminer. These are great miners that can replace about 3 s7s. No refunds will be granted. Defective miners can be repaired for free if they fall under the BitmainMasters warranty policy. After the warranty period, machines can be repaired at the cost of parts and labor.
If you notice there are some loose heatsinks when you receive the miner, please inform us by email to info bitmaintech.
BitmainMasters does not take any responsibility for or compensate for any loss as result of downtime caused by delays in transportation as a result of custom formalities or other reasons. I bought two Antminer S9 and now I know why it is called the most advanced miner on the antminer. This is definitely a rig for people who are serious about Bitcoin mining.
If you are looking to get in that field — s9 is your choice. Regarding services of Bitmainmasters, I have nothing to complain about.
They notified me, regarding a delay in delivery, which is fine as I see it. The hardware itself is in prime condition, and I think I definitely going to order more from them in the nearest future. Additional information Power Supply unit is not included.
