It's just Chinatown, Jake.

Seconded. I suggest switching to 220 or adding a second PSU for one of the cards. Also keep in mind that if you're on a 15a circuit, you're pushing its limits and likely those of the wiring.

That makes it not the most profitable for holding, but for long term mining? If it becomes a standard currency and the use drives up, the profit doesn't matter, the mining will still be needed and the coins will have inherent value instead of speculative. But in comparison to, say, BTC or Litecoin, totally, I don't see Sia becoming a high value coin. I see profit coming from mining it, not necessarily holding it (though who knows? Currency values fluctuate all the time).

Possibly, but all that video says is that his phone or whatever meter he's using is finding it in the room he's in. It's not very scientific.

HW = Hardware Faults. Not at all related to where the machine is pointed.

Are you overclocked?

If you're talking about the US, capital gains applies to profit, not ownership. Your capital gains tax applies on profit made since establishing ownership, so if you were to transfer current Nicehash balances held from December? Depending on how long they were in your wallet, you would likely be allowed to declare a loss based on current USD value. So exchanging for GDAX might actually be tax beneficial right now (if you need the deduction)...

My two cents is that if you are dealing with enough money that this is an issue, you should talk to your accountant before making any big moves.

And to clarify (I know you were not saying this, just trying to make what I'm saying as clear as possible), taxable transactions are sales, so the transfer from Nicehash to Coinbase is not the problem part as the coin isn't being "sold".

EDIT TO ADD: Also Nicehash did pay out today if you signed up for the payback program.

At current ROI? I say yes. With batch 2 coming? Not sure; are you looking for a quick buck or plan to run it for a year or so? It's still a gamble, mind, but if you run it until it's no longer profitable against electricity, you should make your money back (and if you hold the coins or buy other coins with them, you could very well earn a nice profit). If you cash out weekly? Probably not at this point, that type of mining is really a day 1 or nothing approach with new ASICs...

I mean, there's a CHANCE it could be like the S9 or L3+ and draw a reasonable profit for a long, long time. Or it could be like the D3 and earn like $5/day or less. No way to know, so basically don't put in what you can't afford to lose. If $3K is a reasonable amount of money for you to spend, my advice is go for it, but the above caveats apply.

EDIT TO ADD: I WAYYY overpaid for my L3, it was my intro to ASICs mining, and I paid like 2.5x what Bitmain was asking to get a first batch one through Amazon. And while that seems stupid, thanks to cashing out a chunk in Dec, I have already hit my ROI, whereas had I bought the next batch it'd still be in the red. So it's all a crapshoot, really.

I already had the 650 lying around. I don't have room in my panel for another 220 right now (only space left is for a breaker box for an add on project), hence 110.

Agreed. It's far more likely that they keep a percentage of the machines and run them before or at the point of shipping, so they probably do turn a profit on mining before everyone else's arrive. But primarily they are a hardware company, and based on the volume of sales I doubt they're hurting for cash...

No, I do not. I said I support many aspects of it. That doesn't mean all of it.

I am jealous of your temps.

1) Mining pool--Luxor is having some sort of problem where their luck is currently at about 40%, so they switched over to PPLNS from PPS. Which means you get paid out in an average over time, but with their luck that low you're still going to make less right now (in theory). Siamining is PPS and currently paying out well. I'm with you though, I prefer Luxor and will switch back when whatever problem they're having gets sorted.

2) .01% is fine. .1% is ok. 1% is too much (opinions vary, but that's my standard).

3) Your cold air is your advantage, these things run hot. But I have mine overclocked (650 currently but usually 631). Overclocking voids your warranty, fair warning there. Your at-the-wall is your call; you can calculate profit with usage deducted at whattomine.com, it's usually pretty close. On a 20a 110 circuit, I'd suggest limiting wattage to 1700W for safety, you likely won't get anywhere near that though. HW isn't necessarily higher at higher frequencies, it depends. 631 drops more than 650 for me. It's more machine dependent.

THANK YOU for this. Swapping over to Siamining until this is sorted!

Nope, they're both. I'm talking about a bug in the A3 itself (that others have reported too). If I make a change, as it is resetting it will either go up 5-10 from the previous running or down, but whichever it is it runs consistently at. So for example, my current temps are 79-75-81. The last time I changed wallets, the temps were all in the mid 80s, so I reset again and they are back down. It's been a pretty common thing based on posts on this board (though I don't know if it is universal or not), so if your A3 is running hot, you might be able to bring it down a bit just by hitting "save and apply".

Just noticed that. Payout still seems about the same so far for me, but now I have to do some income comparisons again...

Ah. CPU mining. Well, yes, you CAN build a cluster and control them that way, but I don't think it's as productive. I looked into it when I bought my little mini-army of Brix i5s and i7s and my take away was that it is no more efficient, and most people said it was slightly less. Might be worth it for the convenience, but writing automation scripts is just as easy AND allows you to control each individually if they go down or need repair. YMMV, and of course half the fun is messing with the machines, so do post your results!

I'm running 631 @ 88% fans currently (100 makes an annoying vibration in my floor). Running fine, temps in the mid to high 70s (pulling cold basement air), though I am still baffled by the whole "if you reboot, your temperatures change by 5-10 degrees" thing.

I read that before I even got my miner. I see no problem with it, and in fact support many aspects of it.

I'm also running 120; my set up is, currently, one APW-3 on two boards and the mains, one 650W PSU on the remaining board. Once the profit decreases significantly, I will undervolt and leave it on just the APW3, but the current hashrate is worth the electrical cost.

No, it should be on the website though.

If your mobo can handle it, I would assume Ethos can too, but not sure. You can try writing the devs, they usually respond within a day or two.
