Bitmain crypto mining markets share is dwindling

Once considered the industry leader in cryptocurrency mining, the market share for one-time dominant leader has diminished as competition continues rising within the crypto mining sector. Based on the data from, the Bitmain owned mining pool now only accounts for roughly 15.7% of the blocks mined on the BTC network.

Startup competitor Poolin has emerged as the new leader in the sector. The China-based firm was founded by former Bitmain employees in 2017 and has taken a slight lead over, mining 17% of the blocks on the BTC network. The pool’s swift rise started in late 2018 and steadily continued during 2019.

Mining pool F2Pool is in second place, with 20% of the hash rate. Rounding out the top four is AntPool, with a 8.8% hash rate share. Of the four industry leaders, Antpool is the only pool whose market share has been consistent during the past two years. Bitmain also owns Antpool.

Unknown pools merged together to continue to account for the most significant share of blocks mined on the BTC network with a 21.8% market share counteracting the mining centralization. Since mining is a critical component of BTC required to keep the blockchain updated and secured, unknown pools undoubtedly help by keeping the network decentralized and block rewards distributed.

Overall the increased competition and parity is a positive development within an industry previously concerned about the alarming state of BTC network mining centralization.

During the first half of 2018, Bitmain mining pools, AntPool, and ViaBTC grew so dominate that they nearly controlled 51% percent of the BTC network’s hash rate. If mining power is centralized in a few hands or a single authority controls the majority of the hash rate, it opens the door to collusion to orchestrate a 51% percent attack to reorganize the blockchain and start double-spending cryptocurrency.

As the competition for the top spot on the BTC blockchain intensifies, many miners have…
