A920 is part of the flash sale, confirmed by Lily.

A921 is out of stock. A851 is the only other available option from Canaan.

So 20th at 2050w is potential max draw?

Essentially mikey is saying you need to ensure static pressure.

Funny how the GMO thread has turned philosophical in a sense.

More manufacturers allow for decentralization. Essentially you have to look at it like a free market; more competition, more innovation and progression towards a better product in this case.

Zero competition, or a single manufacturer; leads to poor and selfish, "un"-innovative business practices. Shadow mining/extended "burn in testing" is one example. Essentially manufacturers kill the market they desire by mining. Lower the difficulty, the more profits, the more attractive their product.

It's a balance you rarely see or have seen in this area as these are just two extremes of the spectrum to provide relevance.

I'm interested in playing with these but seems my poor software ability will be a hindrance.

Finally got to my draw check on the two 821's I updated. Together hashing 20TH at 1970w on an apw5.

Sexy. We'll get a listing up shortly.

Duties should only be applied to the unit cost not shipping. Who's your shipping service?

Slush wont payout multiple times a day but will find blocks multiple times a day one s9 you might get a payout without added fee in addition to the 2% taken out in 2 weeks. I would recommend ckpool.org myself but payouts are will be slower closer to a month but zero fees.

Lack of capital imo, monies were refunded. Hard to have a lengthy pre order when consumers know competitors will be coming out with gear and will certainly match or beat spec with earlier release dates.

First batch had a late Jan release from what I recall.

I ordered some equipment to monitor power draw. Hoping to update when some things slow down.

Merry Christmas to you too, welcome to the pool!

Yea, not all SD cards are the made the same. I would look at an A1 or A2 rated MicroSD if you're using it for more than file storage. I run a full node on a 256 microSD with zero issues.

Yea, your thread has been pretty a good read. Hope to upgrade while the flash sale is rolling.

Market shift is helping bring hash back. S9's are more profitable at higher power rates. I think at my $0.10 rate I'm "profiting" 0.13/day. Then I'm mining and holding.

I'm wondering with the talk of pulling $BTC from exchanges and hot wallets on Jan 3rd, with less $BTC in market in a few days if we'll see a price surge with the added scarcity. there are still a lot of miners who mine to a pool or directly to an exchange or hot wallet. Myself including till this summer.

edit: of course market dips when I post numbers.

Looks good. My father in law brought me 1.75L of bourbon. Maybe that will help hit a block, or two, or three?%

Good to know if I'm able to upgrade soon. Hopefully the group buy I'm in fills out. 

De minimis value makes these cost effective still. we've provided a cadence for shipments that works for large orders for buyers.

You can still get s9's from bitmain. They're just reluctant to advertise it.
