Compared with well-known companies in the Bitcoin field such as Coinbase, Circle, Blockchain, and BitPay, the role of Bitcoin miners seems to be much more low-key, but their importance to Bitcoin is no less than these startups. 

10: Kano CKPool—2.77% (hash computing power)

CKPool is a standard mining pool founded by Australian anesthesiologist and programmer Con
Kolivas and Kano in September 2014. In order to spread the risk, the two also created a private mining pool-Solo CKPool.

This means that users can pool resources to mine Bitcoin blocks faster, but only users who discover blocks can get rewards.

9: KnCMiner—3.26%

KnCMiner is a Swedish mining company. Given the limited processing power of general computers, most miners in public mining pools purchase mining hardware from companies like KnCMiner.

KnCMiner received a £9.6 million Series B investment led by Accel
Partners in 2015. KnCMiner claims to provide green energy. It currently has a data center in Sweden and is planning to expand to Iceland and Finland.

8: HaoBTC—3.66%

HaoBTC is a Chinese Bitcoin company. The company is headquartered in Zhongguancun, Beijing, and also has a Bitcoin mine in Kangding, Sichuan.

According to the company, it currently has tens of thousands of users.

7: Slush—4.15%

Slush was founded in November 2010. It is recognized as the world's earliest mining pool, and its influence is still great today.

6: BitClub Network — 4.15%

Unlike other mining pools, BitClub Network did not reveal the name of its founder, only saying that the mining pool is operated by a team of entrepreneurs, programmers, digital miners and MLM experts from all over the world.

MLM (Multi-Level Marketing) means multi-level marketing, that is, each user can get bonuses by inviting new users. Because this model is quite similar to pyramid schemes, it has been controversial. However, BitClub Network insists that it is legal and not a "Ponzi scheme."

For some users, BitClub Network is like a cloud mining pool. Users do not need to own their own hardware, but only need to pay rent to Bitclub, and Bitclub will provide them with the corresponding equipment. However, miners with their own equipment can also join.

5: BitFury—8.61%

BitFury was founded in Russia in 2011 by Valery Vavilov. It has management departments in San Francisco and Amsterdam and is a very famous mining hardware investment company in the industry.

In Vavilov's view, BitFury is not just a Bitcoin technology company, but a comprehensive Internet technology company. Vavilov said that in the next three to five years, the company will expand to different areas of the Internet to maximize the value of computers.

In July 2015, BitFury received an investment of 12.8 million pounds from DRW Venture Capital, iTech Capital and Georgian Co-Investment Fund, and this year it received a stake from China Credit under the Pioneer Group.
