It requires some time to implement Market orders and we will work on it later.

You can just buy at 5% higher price than current, and sell at 5% lower price than current.
It is equal to open Market order and you will get best price possible.

Bitcoin mining has become too centralized because of what you mention, mainly because the initial investment is pretty significant, for unit price and setup costs. Bitmain is too interested in profits to give smaller miners a chance at getting into the game. Plus the T9's 11.5TH is nowhere near powerful or efficient enough to give substantial enough returns for the price they ask. But running costs can be reduced if you setup in the right environment, as well as labor if you have the skills to do most of the work yourself. I think Bitmain just serves the big miners now, so if you're a small miner best to look into other crypto's to mine.

Its hard not to point out that that is well over 1BTC/TH - a price that was considered competitive at only slightly lower efficiency over a month ago, and when bitcoin prices were almost 50% higher.

Definitely holding off on the hardware orders until price pops back over $400

Which mining hardware is?

If BTC is now 260-270USD, difficulty seems going up, then S5 for price 401USD + shipping is very overpriced.
I wanted to buy around 30 units, but price have to be  less then 350USD.

Thx, It works well.

The other end of the 12AWG wires

2kW x 2 load sharing on a single rail.
Runs on 1 in a pinch but at the limit and down to only 89% efficiency.
I got space and more PSU for other Nep but will replicate 2kW x 2.
8kW single rail and I don't need to meet personally at my home.

It has a jacuzzi. (top center)

Also note (lower right) easy access for small children to experience 120VAC firsthand.
Not TOO easy though, short ones must use available step stool.

And a heated outdoor patio. (or garage)

The business end of the loop running during construction.

I constructed a pentagon and recited the verse and all that appeared was an empty V8 bottle.

I might flip the PCB so WB are inside of pentagon with straight barbs for smaller footprint.

I usually refrain from prototype pics, but this prototype is less ugly than most of my monstrosities.
I hope to approach the 'pair of WC Saturns complete with PSUs in one case' level of fit and finish.

YMMV

I have few second hands units S2, i am willing to sell some. In case you are interested, please PM me. I am from Hong Kong, but i am shipping with DHL, so it arrives after 3-5 working days.

Got mine S1 last night and plugged it in straight away. Is it normal for it to be that loud? Also when it starts, the fan seems to be making some clicking noises, they sort of disappear over time as you can hear them anymore over the noise of the fan spinning, is this expected behavior?

Seems sales have stalled for a bit.

Down to there are only 866/1500 Neptunes
