Prices and specs are similar to T2 Turbo and M10. Not more efficient than M10 or A9 if their specs are legit.

A9 is around 57 W/TH (30TH/s @ 1720W) - Price and shipping unknown
M10 is around 65 W/TH (33TH/s @ 2145W) - $1888 for 9/20 pre-order
T2 Turbo is around 83 W/TH (24TH/s @ 1980W) - $1350 and shipping now

Supposedly began construction for 9k units in Russian data center in April 2018. I do remember seeing some Russian miners that looked similar in design that were being called a Bitfury/Facemen B8 with similar 60db noise levels, but don't know if they were legit either. They list the B8 in their whitepaper with S9 and 841 comparisons, so maybe it was only sold there. I'm still skeptical.

Saw a bunch of paid PR on this recently and not sure if it's legit, but seems to be since they aren't just 3D renderings and supposedly shipping September 15. Also not sure if these are the same guys that started scamming everyone years back, but site says they were founded in 2017, so may be a different company with same name.

Two different models:

BITTECH One - $1470
28 TH/s @ 2200W



BITTECH One Mini - $880
16 TH/s @ 1150W

Noise level of both is supposedly < 60db.

Found this older video, which makes it seem like they were initially only going to sell under service contracts, but appear to be selling direct now while also still having contracts if you want them to host:

New design looks like cry for help. Guess they have to offload it all somehow since more efficient gear has already beaten them to market and at lower cost. 33 TH/s @ 3,417 watts  

All of the firmware for previous models has same naming convention and works on B+ for me. This is next test version:

Not really their own numbering style. It's zero-based numbering, which is used in almost every programming language since C.  

NiceHash is garbage anyways.

My coupons said they were only good for 821 late March batch while supplies last. That batch has been long gone.

Probably a combination of both. For many, mining is still profitable until price goes below $6k. Even then, many will probably still mine at a loss believing the price will go up. There are numerous 20-30+ TH/s ASICs available now or coming out in the next several months. Who knows if any manufacturers are also mining with them or not.

I wouldn't even consider an ICO or relying on outside investor funding if all you need is $100k to start. You should be able to get that easily through a small business loan. Many startups, not even crypto related, fail because they are primarily relying on and burning through investor funding, refuse to invest in themselves, and on top of that, have absolutely nothing generating real income to even pay the bills. If serious, what you and your team should do is invest in yourselves, build a working prototype, and go from there. Investors are more willing to invest in something when you can show them you are invested in it yourself. Most want to see that you have already done all the initial leg work and that all you really need is funding to scale.

I think you will have a difficult time getting investors if you are positioning yourself in Asia while claiming to be "fighting against" the Asian ASIC monopoly.

What are the specs? I'll probably hold out for the 7nm unless the 851 is $1k or less. Seems like a repeat of 821 and first batch buyers will just get burned again when they release more efficient model shortly after that will probably be cheaper. 821 preorder was $2899 and shipped about 2 weeks before 841, which was $1999. I'd imagine not many other than first batch buyers bought the 821. They do have an opportunity to sell a lot of these if specs are equal or better than T2 Turbo and pricing is better than Inno; $1350 currently and shipping in 2 weeks. 

Listed wattage would put you around 21.5 amps for 3 units and 14.3 amps for 2 units.

Mainly so I don't have to add a switch, more controllers, cabling, and create more points of failure. I fully understand the issues with upgrading firmware and that under/overclocking settings will apply to all units. I run on default settings and currently mix 821 and 841 units without issues.

I have seen recent activity on the Avalon 851 firmware and guessing it's probably for this unless they are releasing a slower model first like they did with the 821. Hopefully you'll be able to chain these with the 8's.



I'd guess that they are just waiting to shit on the competition. If they already have something similar or more efficient, they could sell it at 2x's current S9 price and still be cheaper than everyone else.

Research school's residence hall rules, Internet use, and other policies before investing. Not worth ruining your future. Every school I ever went to did not allow commercial use of Internet and those policies were in place well before Bitcoin existed. Most colleges have a list of approved appliances and many won't allow you to install portable heaters, AC units, or anything that can produce enough heat to start a fire due to fire hazards and electric use.

And a 43" TV mining at 2.8TH/s.

I'd be leery on a presale. Just look at the M3 that went from almost $2k to under $300 from price wars and market fluctuation. Was a nice pump and dump. Glad I sold all mine shortly after receiving. They used more power than advertised too. Bitmain or Canaan has to be releasing something more efficient to start new price war for GMO and this. Someone will most likely be shipping something better/cheaper before these and GMO even start shipping.

Tell him he can send to this address and then he can be worry free: 3KyU7pmVWDQfowmK1WXewkh8WqKD7oVaet

I was on Antpool briefly since Slush and no other pools were working for ZEC initially. Very high rejection rate. Switched to Flypool which was better. Currently on Slush with zero fees and getting 0.20/day. A lot of people stopped mining ZEC on Slush over the past few months but slowly coming back and hash rate has doubled from new ASICs.

Slushpool is currently working now.

Alternatively it could just be the equivalent of 2 minis already overclocked with better cooling. 6 connectors means it only has twice as many hashboards. If they aren't bigger hashboards with more chips then they could just be testing the waters to see who's willing to pay. Might be reason why they aren't listing detailed specs. Jihan confirmed it's existence before minis were even shipping and said it was louder and 3-4x faster than mini.
