Unfortunately, the chip community is plagued by these types of phony miner companies mining use pictures of miners produced by other businesses. Package size is online estimate bitcoin on neighboring components. A3 BCT a Jul 14nm chip. High efficiency claims were made by BitFury  that at this time seem unrealistic. Hashing24 has been involved with Bitcoin mining since The company currently supplies chips for a number of firms set up solely to mine cryptocurrencies, including the China-based Bitmain.
Most links below will lead to external sites. Users purchase Cloudpacks which can then be used to build an index from pre-picked sets of cloud mining farms, lotteries, casinos, real-world markets and much more. Efficiency is what drives the margins in Bitcoin transaction processing. Generally presumed to have been dishonest in their presentation and pre sales.

Online considers this their 'Gen 2' product. Genesis Mining mining three Bitcoin cloud mining plans that are reasonably priced. Top 8x8mm Bottom 9x9mm. Used manipulated images of bitcoin AC Ryan mediaplayer to bolster credibility. Chip was projected tape-out date. The datasheet mentions further core frequencies of MHz through MHz which would yield 3.
Other bundled equipment may be included with your purchase depending on the seller. We recommend purchasing the Antminer S7 or the Antminer S9.
You can use a bitcoin mining profitability calculator to determine your estimated cost of return on your mining hardware. Be sure to take electricity costs into account. Most mining hardware appears profitable until electricity costs are accounted for. Good Bitcoin mining hardware needs to have a high hash rate. But, efficiency is just as important. The Avalon6 gets 0. The Antminer S7 is more efficient, with 0.
The Antminer S7 also costs much less, and comes with 4. The AntMiner S7 is clearly the better option between these two miners, which are currently the most efficient miners available for purchase. To improve your efficiency, there are also companies that will let you order hardware to their warehouse and run the miners for you.
You could also cloud mine bitcoins. But both options are a lot less fun than running your hardware! Bitmain — Bitmain makes the Antminer line of Bitcoin miners. Bitmain is based in China and also operates a mining pool.
BitFury — BitFury is one of the largest producers of Bitcoin mining hardware and chips. Its hardware is not available for purchase. Spondoolies Tech — Spondoolies Tech is an Israeli based mining hardware manufacturer. Date is for tech availability. Unknown status, was met with skepticism at various forums. Little is known about this chip outside of its purported use in hardware that could be rented early cloudhashing.
No page appears to have details the now-defunct website mentioned a day delay in tape-out , and the validity of the company's claims have been called into question. The conflicting efficiency data stems from claimed efficiency in text versus apparent efficiency as shown on a purported miner display.
It is currently not known if the chip claimed is of their own design. Hash rate and efficiency are derived from 'M20' hardware claims. Date is first appearance of company's website, chips are claimed to be expected Q4 This company is the subject of several scam allegations at BitcoinTalk. The hardware which is claimed to incorporate this chip is only available for pre-order with delivery planned for January Not to be confused with ZTE Corporation of telecom fame.
