Overall the % of stake is the same. You'll just get more smaller stakes. Like both a 2000 and 6000 will stake. My 2000 gave me 5 coins~ after a week and my 6000 gave me 15 coins.

Dunno, they didn't say they would not release a rack mount, they just said they were releasing the smaller factor next. It was supposed to be last month but now they said they would announce at some point within a month or two.

Where do the specs cited come from? That's not what one would expect from Bitmain. Unless they are giving up their small form factor for more big mine oriented ASIC. That would further favor hash centralization however...

And i believe the minimum to stake is 1k anyways, so once they get split down to 500~ they won't stake anymore?

I see, but there is no point in comparing your electricity cost to the rest of the UK... You're actually competing with maybe something like 90% of the miners running on 0.03-0.05usd/kwh. With your 0.15usd/kwh you'd be better off using those 0.08usd/kwh datacenter or trustable cloud which varies. But even using overpriced hosting at 0.11usd/kwh would be better for you.

Alot of people recommend not mining if you're at 0.1+ and that you are, it seem. So regardless what you get, profiting for you will be hard. Good luck nevertheless!

I don't know how prohibitive shipping would be, but for the best Hash per Watt and smaller units, there ain't alot of choice. I'd go with used Antminer S3. There are very few manufacturer that still produce ASICs.

At the moment Bitmain. Spoodoolies make some ASIC too but with some bigger form factor and louder units, Avalon too, but the Avalon4.1 are kind of expensive and rare. If you have to pay significant shipping cost per unit, you'll probably have to go with the more recent unit, the Antminer S5, but the GH/$ is more expensive. The Antminer S5 is no longer on production so you will have trouble finding unused units. Even Bitmain now sell their used S5 only.

IT also depend on how much noise you can afford to have.

No, it really depend on the efficiency of the PSU. A EVGA G2 would do it no problem. Also the cap are high quality so you could run them at near max load for a long time without any problems, so at a small efficiency loss you would still have some headroom.
But for example i have 2 undervolted S1, they take 150~ watt each, on a 94% PSU they take 160watt each~ or so. On a 430w Thermaltake with no rating they drain 410watt or 205 watt each +10watt for the psu fan.

So it depend on the efficiency rating of your 750w psu.

And seeing the marginal daily gain of the S5, i would recommend you just wait and see if the S7 comming out SoonTM will be ROI-able, because at your very high electricity cost you won't ROI it. To be honest your electricity cost is so high it would be much better for you to have it hosted.

They're not skipping a generation, the even number generation is a Rack mount unit, the uneven number is a small form factor. The next unit coming will be s7 as reported by several users of reply from Bitmain.

Gotcha. Isint it normal for them to be 6~degree apart? I never found out why, maybe its the positing of the chips. (Since it basically just report the temp of itself, not necessarily the actual temp of the chips on the board) depending on where the chip is placed, the temp is more or less truly representative.

So you say the 2 new old units are odd. Do you mean more so than other S5's?

I have not received differed deposits of any kind. Just the finite value being off from what the bot reported. I sent a PM, marco will probably reply when he have the time.

Edit: Nevermind for me, i found out how unsecure PW saved in chrome are and retrieved it there, i will change my email to gmail.
@Kano

So there was an issue with password recovery with Hotmail. Thus you now reject Hotmail as new registering email. But my e-mail is already set to an @hotmail.com. Right now i'm asking for a recovery password and i am not receiving the recovery e-mail. (After a few minutes)

So what would the procedure be for password recovery for people who previously registered with Hotmail?

That's a bit of an exaggeration but when i think about it, its sadly not much of one. The law is open to interpretation, there is a huge grey zone where you can break the law even if you're not, or not be breaking the law even if you are, or should be.

I'm just thankful i'm not in the US, where bitcoin is in a negative legal status. It's much better in Canada.

I see, they work well performance wise? I am supposed to received mine tomorrow. For some reason, having to pay import tax for UPS is an "unexpected issue" and that delayed it to tomorrow or something. Well whatever.

I might try your pull the pin trick to get 100% fan at all time, maybe not, the melting issue is supposed to have been fixed and there's manual user control fan firmware out now. I will of course test that and also cut its internet to see how it reacts.

If i can keep the fan speed dialed down just a bit and it doesnt wind down when it lose connection, i might go for it.

Ugly, cheap and effective is good in my book. Go Pragmatism.

For fitting the PSU, that's really easy. I didn't fit it in xD. The psu is resting next to the Zeus, so that void any stuffing and cramming issues one might have. The stock cables from EVGA are very much quite long, and so i have a lot of range to where i can put the psu. On top, sides, behind, etc. Prior to changing the cable, i had terminal melting at "stock speed" 328mhz after about 1 year of use.

The server PSU are rated 1100 so i could push them if i wanted, but the fan produce a high pitch noise and is unbearable when the load is too high. At the moment i found the lowest freq that doesnt generate HW, i litterally went from non stop HW at 275mhz to 276mhz which i get 0 HW (well, beyond the regular 6-7%~ rareish HW that you get overall). I lose 4mh over it and it think its a good sacrifice. The PSU go down to 820watt usage with 94% eff~. At which there is a high pitch noise but the dB is low enough that my ear stops bleeding.

And it doesnt really fit in in lenght, but for thermal dissipation i still slided in it in the middle, there's some holes in the bottom of the asic, i ran some long tie wrap to hold it in position, put some foam underneath it to point the exhaust at the middle fan, so the heat it generates is expelled outside directly. Added some tape because nothing is complete without ducttape. That way it doesnt budge as much.

And thats it...

Eventually i'm going to sell and get rid of all of this, because i am going to evolve my mini farm into something mostly quiet. I might keep the PSU, as if they are run under optimal load (or anything under 700watt) i can't really hear them. We'll see as the Thunder X3 obviously blow over the noise of everything else.

I would doubt so. I received the tracking number and confirmed the package was in UPS hands at the same time it spiked. I do not think the machine can teleport from the mine, while in use, to packaged and in UPS's hands within minutes.

But it is possible after making room in the storage, they went back to their mine and started unplugging more stuff and then plugging new stuff, refilling the storage with more S5s.

I have the desktop chrome plugin version...
It's the third time this week i come to try to access my wallet and i can't login. Is there a way to to get a desktop version that can login even when the website is down? Otherwise i don't get what's the point of a desktop/web wallet hybrid with better security if you can't access your BTC half the time?

Haha, the cables i made were much simpler than pci-e, they were single cable ring terminal for the thunder x3. I replaced all the confusing cables by a single 14AWG stranded cable.

Its good cable but horrible crimp. I was able to pull fairly strong without the crimp budging so i think they will do until i get rid of the ASIC or replace the terminals.
First crimp ever;


I then covered the +12v with red tape but yeah. xD

Indeed, though the values are always guesstimates from the network blockrate. Nevertheless it still looks like the rate dropped sharply exactly at the time where they shipped me a batch, as if they offlined a batch after finishing preparing and offloading the last batch.

Also i use this website to track the hashrate and diff; https://bitcoinwisdom.com/bitcoin/difficulty

Ah well i'm glad you say so. Usually that thing on other websites, amazon and most listings, it goes for 30USD so i was happy to find it for 13USD~
In a pinch before i used regular pliers and a hammer and err. Even tho it "works" i wouldn't trust those ending for long xD

......Right. If only my thousands of $ "worth" of XPY wasnt actually worth a total of 2 dollars, then maybe i could buy some stuff on Coinstand 2.0 xD
Hah well, maybe the XPY will eventually one day reach some sort of value where the XPY i have will be worth recovering my password over.
