I've never really understood the appeal of a "portable" mining unit. It's never been obvious to me what would motivate somebody that had the electrical infrastructure in place, and Internet access, and location to park the thing to then decide they just wanted to move it? I understand the idea of deliver a complete "box with mining hardware" to a customer with plenty of money and adequate electrical and Internet. But what would motivate a subsequent move and making that "easy" having a big value?

Just my random thoughts on the idea.

I can't answer questions about the D3, and really should be taken over to an Alt-Coind discussion forum. This specific forum is intended for BTC only. It also strays pretty far afield from the s7 question originally proposed.

Looking for sure to be a pretty good decrease.....

Based on the interesting link provided by abeandund, it looks like several hours ago, there was a huge drop in BCC difficulty. A couple of hours after that. there was a massive influx of hash rate. That increase obviously didn't come from hardware being installed and deployed, nor was it likely "idle hardware". It obviously was existing hashrate that was re-deployed.  So until the next upward BCC adjustment, or the next BTC adjustment down, I expect BCC will have very short confirmation time because it's massive hash-rate (for now).

This is such an interesting dynamic to watch, though probably not good for BTC long term.

While I completely spaced on getting in my pick, the gray trend line on bitcoinwisdom looks like we have had a bunch of hash rate arrive, presumably re-purposed from BCC mining. Is there a good way to tell if that's accurate? Is there a "BCC wisdom" equivalent? It would seem you could better correlate a BTC hashrate increase with a recent positive jump in BCC difficulty, and then the reverse when BCC difficulty drops.

Just some random thoughts......

While there is plenty of time for you to be proven right, right now the chart is still solidly in negative territory.

Does anybody know how long the EDA phase lasts for BCC? Is that an indefinite "feature"? It seems like it can really shift SHA-256 hashing back and forth pretty hard against BTC.

If you have heard of an "Antminer xx miner" then you have heard of Bitmain.

In general, this kind of question cannot be answered as stated. The primary key component to any financial calculation will be your cost of electricity, and then cost of any other infrastructure to house or maintain you mining setup.

Personally I don't know how to ignore the price of BTC, or your preferred Altoin, since you stated the requirement in terms of USD.

Is the $1000/month, revenue or profit?

While it is available, it's WAY too early to try and pick. Read above for details on when you can actually "make a pick".

While this is quite welcome, the BTC price is clearly stuck way in the past.....

I would have thought the BCC "Emergency Difficulty Adjustment" (as I understand it) would have "expired" by now and it would be back to the normal 2016 block adjustment interval. Right now it appears that BCC still needs this "crutch"?

That seems like a poor situation long term, though maybe the "Emergency" only needs to last a while longer.

I can understand why BCC seemed desirable to Bitmain since it would supposedly increase the set of folks that would want an S9 (i.e. BCC-only miners).

Most miners that I am aware of have an Ethernet jack, and expect "wired" access. There are a variety of ways to finesse that, but I don't think any current miners have WiFi built-in.

Do you also have ready and reliable Internet access? If not then you are pretty much out of luck for any crypto currency mining.

You might want to make clear what it is that you are seeking. It sounds like you are really looking for "minority partners" and not any employees. Those folks have to take a risk that they will not realize any short term profit, and have to trust that sometime in the future they will be rewarded for their efforts. This is actually a high risk venture for both your new "partners" and you as well. You have risk in hoping that you American based "partners" don't take off (i.e. abscond) with the hardware. Any "corner cutting" in terms of permits and government regulations could put you at a severe disadvantage in terms of seeking any legal remedies if your "minority partners" prove to be untrustworthy.

I am also surprised that you think you can save any money by attempting to use H1B Visa holders. Most of the H1B folks I know are pretty well paid, and your concern about $11/hr would be way below what they are earning now.

Perhaps you are thinking that any "minimum wage" rules only apply to American citizens? As far as I know, that's entirely untrue, even in the State of Washington. Besides the skill you are seeking in general will pay way more than $11/hour regardless of work permits and citizenship.

I expect you will need to re-think your plans some.

Is there any particular reason you can't hire American citizens to do the work you want?

If you are thinking of replacing an Antminer S9 (or S7) fan, there is more to it than just CFM. These miners are pretty "dense" in terms of their heat-sinks inside, and require a fair amount of "pressure" by the fan in order to actually push the air through the miner to the other end. Virtually all fan CFM ratings are in "free air" meaning that they don't encounter obstructions to impede the flow of air. It's easy to find a high CFM fan that fairly quiet, but when paired up to an S9 won't actually push through enough air.

The "static pressure" rating of the S9 fans are pretty high, and that's a significant part of their noise.

What's even better is that they offer a 130 TH/s miner for just $2000 more than the 90TH miner. All in a box just a bit larger! Or you can get a rack with five of 130 TH miners (i.e. 650 TH) for a mere $30000.

Hurry, this offer is for a limited time only. Operators are standing by......

I am sure they would be happy to take actual cash, or Bitcoin.

   

Right now, it looks like it will be another roll-over.

Looks like going forward, difficulty changes may well be driven more by BCH activity and price, and less by new mining hardware being added, or old miners being removed. Wild times indeed.

This isn't so much a technical question, but rather how the forum will treat the hard-fork of BTC into BCH.

Is BCH considered an Altcoin and hence unwelcome to be discussed, or is it so close to BTC that it's OK to include it? I am thinking this same question applies to all the sub-forums (e.g. Hardware, Speculation, Pools, etc).

I had no god idea on how to get some insight into this, and the various moderators might want to update their various "sticky" threads with some kind of guidance.

+2.5 = alh

Thanks again for running this Phil. I thought more hash had been shifted to BCH, but looks like not.

While I have participated in these before, I have lost my sense of how the range works when we are into negative territory. If as an example, what would I choose for the following:

Estimated Next Difficulty:    922,529,973,147 (-0.08%)

Would that be -.1% -or- 0.0% ?

I'll wait a bit to make a guess, but thought I would ask now, since it seems possible to me will be in for decrease in diffiulty.

Thanks for doing this again!!!
