i wish there was more competition in the mining hardware scene. i feel like there still is a dire need for more companies in other countries that get into ASIC production.
last year when price was rising fast i heard a lot of news about many different companies (like in Japan and Russia,...) were getting in. but i never found out what happened to them. did they eventually start their production or did it die there?
Halong Mining went silent several months ago. They sold out their first batch or two and that was it. Various companies like Obelisk believe that Bitmain is "playing dirty" and convincing Chinese manufacturers to cut off other ASIC producers like Obelisk and Halong.
GMO released a 7nm miner earlier this year. I think it's been sold out for a while. As mentioned in the article, Bitfury recently launched a new 14nm miner.
That's all I can think of off the top of my head. It seems like Bitmain has definitely got other companies out-scaled. I think all the hype last year really underestimated their capital, scale and ruthlessness.
