Sounds like you have the security taken care of.  I will have similar security as well.  I only hope I don't have to do it at multiple sites.  My wife is staying home in Alabama for the first 4 to 6 months.  She's very supportive of our mining aspirations.  As it sounds like your wife is supportive as well.  It's good to have that support.

Yeah, having your wife be your best and foremost partner helps a lot! Especially because when sacrifices have to be done (think getting loans, late-hours miner configuration, etc) they are there to help and move things along!

Mine truly is my best friend and partner in life.  As for loans, we are trying to do this without loans.  Hence, only 50 to 55 rigs starting out when arriving in Washington State.  I may consider a loan after 6 months out there.  At the moment, I'm just hoping the difficulty doesn't go crazy between now and then with the price of bitcoin remaining the same.

I'll chill out now with the somewhat off topic communication.

Multi site i do not envy an outage like you mentioned.   Also on mine I have security system with cameras.  Would get expensive to add some things like that it seems if you spread through to many places.

Cameras and biometrics on each site (as my usual business line covers those two areas), except for the "home" site which i just have a camera and a good wife taking care of the miners hehehehe

How are you hosting that many?  I felt like i was decent on mining with my 100 amp mining setup.... but dang 50+ of these things.   That is a lot of power.

I've gone the route of multisite mining... Having one dense spot of miners is overkill for most.... However, multisite is a PITA when you have outages and such.

That's what I might have to do in Washington State.  However, I'm hoping I'll be able to avoid this.

How are you hosting that many?  I felt like i was decent on mining with my 100 amp mining setup.... but dang 50+ of these things.   That is a lot of power.

I was thinking about increasing the power here at the house to 400 amps service.  I had the power company come by to have a look at my feeder cable to see if it was large enough for the upgrade without replacing the feeder cable.  He said the existing cable was good enough for 500 amps max.

However, I decided I prefer to move to Washington State if the difficulty doesn't get out of hand with price of bitcoin still low.  If price of bitcoin gets higher to offset the difficulty rise, I'm fine with it.

Edit:  I'm actually running 150 amps during the winter when I had the other rigs going.  I couldn't do it during the summer when the AC wanted to come on.  The main breaker would trip...  lol

I could only do 120 amps during the summer.  Which meant I never had the dryer on at the same time as the cook top/oven while the AC was running.  The main breaker would trip.  Then I just got to the point where I would cut of one or two S4's if I absolutely had to cook and dry clothes at the same time.

Thank you for posting!  I do remember your setup man is it very very nice!   

Those amazing pictures jogged my memory.  Good luck on your last auctions!

Thank you, notlist3d.  Mighty kind of you to say.  Hopefully, these last 3 sell fine without another hick up.

Damn, I wish I had room for that many.. How about I buy into the 41-46 order? Aka. you host a couple for me? ^^

Sorry, I will not be hosting.  I will not have the power I desire when first starting out for hosting.  Maybe later on.

Also, if the difficulty is fine and I buy the other 41 to 46 S7's, I will be moving to Washington State.  Meaning, I will no longer have the same setup you see in the pics.

Cant wait to see your new setup dmwardjr  Grin

I WILL TAKE THE PICS DOWN IN A COUPLE OF HOURS MODERATOR...

There won't be much change other than gear.  I sold all of the S3's, S3+'s, S4's, S5's and SP20's.  Well, I still have two S5's and one S3+ remaining but their auctions end in 3 days.  I had to re-list them.  That was a bad number to re-list after 44 auctions.  Only 3 of them didn't pay because they were all zero feedback winners who did not pay.  Hopefully, I don't have zero feedback eBayer's win any of these last 3 auctions.

Here's a pic of what "was."  [The S5's were not available yet when this picture was taken].  That is NOT burn marks on the wall.  That is where I painted cast iron staircase spindles against the wall.



Here it is now with my last two S5's and one S3+.  This mining closet is itching for some new HW.  You might notice the grilles installed in the door on the side where I had most of my rigs.  It worked out quite well with the 14,400 CFM exhaust fan suck air through those grilles into the rigs.



Here is a pic of the outside of it:

I actually think the other companies will hit the network hard with a lot of hash at less than 0.12 per GH/s to push out a lot of miners.  It will be rough in the beginning for them but they will ultimately push everyone out.  The chances of them doing this during the winter is not as good as this coming spring.  So, if people are going to continue mining, this winter may be their final opportunity to do it at this low of difficulty.  I can see 90+ billion in difficulty quite easily by spring time with the new rigs about to hit the network.  The only thing home miners have to hope for is an equivalent rise in price of bitcoin to offset it.  That means price of bitcoin would have to be at least $420 if difficulty was 90 billion.

I'm just thankful I have sold all of my rigs.  I had 44 rigs.  I have two S5's and one S3+ remaining.  Their auction is almost over on eBay now.  I had a couple of S4's sell for over $600.  The other S4's were around the $550 to $570 range.  I sold many of the SP20's for more and/or for the same that I paid for them in the 15 package with free shipping.  S5's have been going for around $365 on eBay lately.

I don't agree that we will see a huge spike in hashrate because that would affect the price of BTC too much. Rather they will switch out older hardware for new giving a slight bump in hashrate but the real difference is in their fixed costs - they will make much more profit with the savings in power.

Thank you for your input as well, alienesb!!!

I like hearing from both sides.  I believe I'm going to go ahead and take the plunge.  It's a gamble... but what the hell.  I'm a gambler at heart!  I'm ordering 9 right now and another 41 to 46 the end of December if the difficulty hasn't gone crazy.

By the way, does anyone have S7 coupons they are willing to let go of?

Totally agree... At the end of the day Bitmain isn't a charity, and while they, like other companies in the space can honestly (I hope) state they do enjoy being in the space, it's about profit...

Far too many people still have this utopian home GPU miner hobbyist view of the crypto currency ecosystem (most directly SHA-256), while it's great to believe in the greater good the reality is that at the end of the day it's about profit, if not for the founders of the companies, the investors that helped build them.

No, can't blame them.  I would want to make money too if I were them.  It's not just them and the S7 I'm worried about.  It's KnC and Spondoolies as well.

I'm saying if there are other companies selling mining gear chances of hiking price is slimmer ( I think).   They were making S5's when SP20, and Avlaon 4.1 had stopped making batches.

That kinda gave them 100 percent their choice on pricing.  And I am not saying I blame them or horrible company.  I'm sure it was all a business decision.  I can understand it even thought I don't like it.

Thanks for clarifying about it being pricing of rigs and not bitcoin.

Aren't you the guy who posted photos in the "miners porn" thread? You had that "kid" constantly harassing you.

I remember you had a nice setup, sad that you are getting out of the mining game.

Yes, I'm the one who had that "kid" constantly harassing me.  But hell, a lot has changed since then.  I never expected Spondoolies to stop selling to home miners and stop providing competition in the home mining arena.  A LOT has changed.  I want to continue mining.  It's just too many unknowns at the moment.  I want to barrel ahead and continue but I also want to be smart.  It's possible I could still buy 9 or 10 S7's.  I will say this though:  If I buy 9 or 10 units here soon, that means I'm going to Washington State.  No way in hell will I continue here in Alabama with 10.6 cents per kWH at present difficulty and price of bitcoin.  Yes, I can make enough money here to ROI more than likely, but not near as much as Washington State.  At nearly $2,000 each rig, it's quite a gamble with all the unknowns.

The S5 was unique as it kept making many when other vendors stopped previous gen.  So they kinda had control of market and could do what they wanted.  If there is even just one more company out there releasing to general public it will cause at least stop some hiking of the price.

The chance of another vendor selling to "everyone," like bitmain, is rather bleak, imho.  I think they will mine for themselves and only sell to large operations.  All I know is "I'm scared as hell to buy more rigs now."  I'm actually kind of feeling it is a trap.

That is assuming they are only one selling when it happens Smiley.  If there are other vendors out there it is much different.

I'm assuming you are saying it will halt the hiking of price because there will be more people selling it [creating downward pressure on the markets]?

Well the thing is if you bought btc at 230 and btc rises to 300 you would have been better off holding original BTC than buying the miner.   The miner would cost less BTC at 300 btc value.

So again that went into my ROI notes.   My ROI notes and math was kinda a sad place.

I'm sure it is a great product on S7.  Sorry if I am a little negative after trying to do my ROI sheet, I just got a lot of unknowns when i put it on paper.

Yes, but you know Bitmain...  They will raise the price of the S7 if the price of BTC rises to 300.

Also, if BTC price rises to $300 after I bought 70 BTC at $224, I will have made $5,320

I don't think home miners will ever turn off their gear when difficulty skyrockets, they just sell it to someone with cheaper power costs. Look at how many threads there are in the "Classifieds" section with people in 3rd world countries starting up farms because they have free or cheap electricity.

I think by Febuary the difficulty will be 100G. Because in October or so, winter is coming and many will power on rigs to offset heating costs. There is also these new S7's being produced which will increase the hashrate very fast.

I don't think these S7's will ever make anyone any profit even $1, unless the BTC price goes into the $300 region OR if the equipment gets sold at a high resale value.

If these S7's were gauranteed money makers, Bitmain would just mine with them themselves and just sell us the S5+.


You have a point there with the "winter" mining.  Sounds like I may be holding onto my money and using it to trade pairs conservatively on FOREX.   Grin

I was thinking very seriously of moving to Washington State in December [if not sooner]  to start out with at least 50 S7's (243 TH/s).  I was wanting to be in place with cheap power in anticipation of a surge in bitcoin price by the Spring.  Now, I'm wondering if the difficulty would be so high to make it all for naught?
1836  Bitcoin / Hardware / Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH on: September 03, 2015, 06:18:38 AM
Also remember the ones that will be coming later choose to go a lower NM chips.  So efficiency is hard to guess on some of them.  That adds to me being scared.

Bitmain made a smart business decision with mastering this NM chip, it allowed them to be first to market on next gen.  So I give their R/D department credit for the decision and these chips. 

So there is difficulty and what the competition gets on efficiency to look at when really putting down ROI thoughts.

You have a point there with the more efficient chips from lower NM chips.  That could potentially FORCE a lot of people out of the game with a power push.  It all scares the hell out of me.  Talking to you has me thinking now that I need to hold off.  However, I'm thinking the price of bitcoin could go up soon.  This would make the price of the S7 go up soon.  So many damn variables to consider.  My brain has been burning the past 12 hours.
1837  Bitcoin / Hardware / Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH on: September 03, 2015, 06:09:38 AM
Difficulty scares me as well we had MANY weeks at 2 percent or so.  Just was no new gear and was a pretty good time to be a miner.

Now this current one is where it get's scary it is high 5's.  So... will this continue we really don't know at this point.    A few more changes we will have data.  But my ROI math I had a hard time currently as I do not know what it will be close to.

And this is for every miner that will come onto market with next gen not just the S7's.

Yes, that is my concern as well.  I'm not sure what KnC is going to do; what Spondoolie's is going to do...  It's just too damn hard to say.  I came close to purchase of 9 S7's just a moment ago but I did not have the method of shipping chosen.  So, the order did not go through yet.  I did not know to take that as an omen or what.   Cheesy  So, I still have not ordered yet...

If KnC and Spondoolies add a hell of a lot of hash, we could see difficulty as high as 90+ billion by December or January.  However, if the price of bitcoin is the same by December or January, that will only hurt them and not help them.  However, you have to think if they shot the difficulty up to 90+ billion that a lot of miners with less efficient rigs in high power cost areas will have to drop off line.  Which means the difficulty would drop to less than 90 billion.  No?
1838  Bitcoin / Hardware / Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH on: September 03, 2015, 04:40:12 AM
I was actually thinking about buying 9 or 10 S7's for now and another 40 in December.  However, I'm quite concerned about difficulty jumps between now and December.  Any thoughts on this subject would be appreciated...

I know as the difficulty rises there will be others to drop out of mining if bitcoin prices remain the same.  Those who drop out will mostly be home miners with substantially high power costs and less efficient HW.  How much of the network hash rate actually falls into this category?  Hard to say...

Any idea how many rigs BITMAIN will make in the first batch?  That will give me an idea (rough estimate) of how much the difficulty can possibly rise each month over the next 3 months.

If you haven't noticed, the hash rate is turning up rather sharply on bitcoinwisdom.com.  Can we expect this angle of ascent on the chart for the next several months?  If so, we are looking at 70 billion difficulty rather easily by some time in November.

How many rigs can BITMAIN manufacture in one month?  Maybe 5,000 units?  Knowing this can assist with determining what the future difficulty can be potentially.

Bitmain is in a rather sweet position by knowing how many rigs they make.  This can give them an edge in knowing what the potential difficulty can be at a particular time +/- about 5 to 7 percent accuracy.

The S7 is definitely a game changer at this point in time.  It forces one to really weigh their potential purchase a lot more.

In case no one has noticed, we have only ONE (1) pool member who added an average hash rate of 12.27 PH/s.  If you look at the bubbles on the "System Stats" in "Pool Statistics" you will see the large bubble with 12.27 PH/s.  That one user has almost half of the pool's entire hash rate.
