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 antminer Bitmain from the 12 antminer 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 bitcoin 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 hardware 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. Was this review helpful to you? Bought two units at the same time from US company because I did not want to deal with overseas bitcoin from China. Manufacturer warranty is 90 days. This Bitcoin company will only let you return it for 30 days.
One unit failed on day 31 and the "return bitcoin was closed. Now I have to deal with overseas repair anyway. In my humble opinion they are antminer best on the market bar none and roi seems to be very quick. Wow, all these beautiful reviews.

However, the wait for the next batch could prove costly, especially antminer factoring in likely shipping times from Bitmain in China.
As most people pay for their power usage, efficiency will probably prove the deciding factor — and currently nothing is more efficient than the bitcoin S9. Finally, it should be noted that the reaction of professional miners to the T9 has not been especially positive. The general consensus appears to be that the T9 is a way for Bitmain to clear stock of sub-standard chips, by running them at higher voltage to boost their reliability.
The downside of this is degraded efficiency. Last updated on July 24th, at
