Bitmain's Hashpower to Fall Significantly

Now the community don't need to fear possible 51% attack at Bitcoin network again
04 February 2019   799

The share of the Bitmain-controlled mining pools of BTC.com and Antpool in the total bitcoin hash rate is about 29%.

According to analysts of The Block, in the first half of last year, the total hashrate of these two pools was 42%. If we take into account the pool ViaBTC, the main investor of which is Bitmain, then a year ago the Chinese giant could control at least 50% of the hashrate. This, in turn, caused fears in the crypto community about a possible “51% attack” on the Bitcoin network.

Now this threat is not as relevant as before, because Bitmain has actually lost the status of a mining monopolist. In confirmation of this, The Block provides a graph in which there is an obvious decline in the influence of Bitmain-controlled pools:

The share of hash-sites in Bitmain-controlled pools is now at the level of mid-2017

Obviously, the Chinese mining giant is going through hard times. It was previously reported that Bitmain suspended operations in Texas and is closing its office in Amsterdam. The company also undergoes a major reorganization, accompanied by a reduction in staff.
