Bitmain has got serious competition. Japanese IT giant has revealed B2 Bitcoin miner with 24 TH/s compared to Bitmain's Antminer S9 14 TH/s. B2 consumes 1950W per unit against Antminer's 1300W per unit. Dough B2 consumes more power than S9, it is most efficient miner on market. B2 consumes 1950/24= 81.25W per TH/s and Antminer S9 consumes 1350/14= 96.4W per TH/s so Antminer S9 consumes 15.5W more per TH/s.
I think that it is great thing for Bitcoin that Bitmain will get serious competition because monopoly of one company is very bed for Bitcoin ecosystem. I expect that techs giants like NVIDIA, AMD, INTEL, ASUS develop their Bitcoin miners because Bitmain last year made a profit around 4 billion and big money attracts big companies.
When all those huge companies enter Bitcoin market, mainstream adoption will accelerate because they will have huge incentive for that.
There are many positive things going on currently with Bitcoin development and future of Bitcoin is brighter than ever in my opinion.
