It would be nice if they had a LIVE feed of bitcoin price at one of the exchanges at the top of the new beta home page; somewhere close to the pool hash rate.  Does anyone know if they already have a LIVE feed of bitcoin price posted somewhere in the beta?

I'm down with using an S5 to mine Bamacoin!

Might like the name, "TideCoin" more.   

LOL


ROLL TIDE

ROLL TIDE, David!

Thank you for your contribution to bitcoin!  Didn't realize we were close to one another until now.  I live in Birmingham.

I'll have to check out the magazine in more detail.

Have a great day!

David Ward

93 cents per day at present difficulty and present cost of bitcoin $408.00.  $27.79 in one month and hardware break even in 97 days.  All of this with free electricity.

Not worth it in my opinion either.  If my electricity costs were free, I would rather have an S4 or S5.  However, it all depends on what one can afford.

You did help me double check myself to determine the safest way to wire up everything depending on what the power company will give me.

I was thinking out loud, more or less, in my aspirations to mine bitcoin.  The Th/s I wanted at first would have required 700 AMPS minimum.  After going to my power company's website, i know they are going to limit me to 600 AMPS at a residence.  Only under unusual circumstances will they put more than 600 AMPS at a residence.  Saying the residence is 20,000 square feet, which would require a transformer service installed next to the home.

Thanks again for getting me to do some research on my power company's rules and regulations regarding a residence and getting me to double check how many S4's I would have on each circuit to achieve maximum hashing power in the safest way possible.

Okay,

Thanks for the info.

It's an option to consider if I want to go beyond the limits the power company limits me to. 

Please forgive me for using foul language towards you earlier.  My apologies!  I would rather have one be a little more tactful at trying to convince me though.  Doesn't mean I'm trying to justify my language towards you by no means.  No one deserves to be cursed out even if I think that someone might be disrespectful or condescending in their word or phrase choices.  I still need to work on my temper a bit...

I'm pretty sure the power company will give me 600 AMPS at my meter.  They will wonder if it is a business ran out of the home because of the amount of power I'm requesting.  I'm sure I will need to convince them it's not a business and it's for personal use with bitcoin mining.  They charge a business almost twice as much for power than they do a residence.  They will wonder if I'm running a business out of my home.  I do have a business I run out of my home.  However, this bitcoin mining is for myself and I'm not writing off anything I've spent for business expenses.

Again, thank you for the info and it's something to consider.

Regards,

David

I see $80 per kW for 12 months and $99 for 1 month.  First off, this leads me to believe $80 per month for 12 months OR $99 for just 1 month per kW.  Is that right?

I'm lead to believe people will send there equipment to you to let you use it to mine for them?

ALSO #1:

If one wants to SHORTEN THEIR PAY OFF PERIOD, simply don't buy more equipment for how ever many days you want to eat off of the pay off period.  Save your money, trade on the exchange with your earnings or whatever you want to do with it.

Once your BTC is converted into fiat and fiat is hand, do whatever you want to do with it.  You earned it.  It's up to us what we want to do with it.

ALSO #2:

At present I have 9.4 Th/s.  You see my total costs of hardware at this point in time entered in the proper place.  You see the hash rate and price of BTC at $425.00.  You also see the difficulty set to the projected next difficulty.  The difficulty is the same in both calculation charts you will see below.  The BTC price is the same.  The hash rate and cost of equipment is what is different.

YOU WILL NOTICE THE HARDWARE BREAK EVEN PERIOD IS LESS [180 days vs. 156 days] WITH MORE EQUIPMENT RATHER THAN LESS EQUIPMENT.

This would be another reason to argue it is worth getting more equipment IF you can get it at a good price and it's power consumption is low.

"Cooling" - That's the beauty of scaling up during the winter; as it is at present!

space - I've already shown you I have PLENTY of extra space [12.5' x 25' x 8' = 2,500 Cubic Feet (CF)] in a room downstairs that my family never uses.  Our family room is 18' x 22' x 8' = 3,168 Cubic Feet (CF).  That is where we spend the majority of our time as a family during the winter months.  We would rather be outside most of the time during the warmer months.

insurance Even if one needed to add their equipment on their home owners insurance, the costs are miniscule annually.  I have a business out of my home that has insurance on equipment in my office in the event of burglary, fire, etc.  The insurance is miniscule annually.  It's not a bad idea for anyone to have important documents, receipts, etc... in a fire safe in their home and/or safety deposit box to show support for the costs of equipment to insurance when filing a claim in the event of a catastrophe.  



Tell me something:

WHY can't rigs #1 - #16 with Air Conditioner, 14 inch exhaust fan, PDU's, Cords, supplies to build shelves, outlets, 10/2 wiring, etc. @ $5,200.00 be put off at a later date for pay off?

WHY can't I just pay power costs ($364.00) [Like I did the first time] to purchase an S4?  Then my number of days till payoff STARTS OVER at the date I purchased the S4 with the BTC I earned?  Also, my investment has increased from $5,200.00 to $5,564.00.  Actually, my pay off will be SOONER because:

#1 - I purchased the S4 at a discount.
#2 - I have more hashing power with the S4 and able to pay off in LESS TIME.  Only my pay off starts over from the date of purchase of the S4.

I'm about to order THREE (3) more S4's with cash and btc, all before the end of this month (November 30th) and my 118 days STARTS OVER (November 14)?  I have three (3) $400.00 OFF COUPONS OF S4 in my Bitmaintech.com account.  I have 1.4 BTC in my wallet earned since my purchase of that 1st S4.  I will end up mining at least another .6 BTC to 1.2 BTC before November 30 to put towards the purchase of those three S4's @ $850.00 each.  

The power costs used since ordering and receiving that S4 (Oct. 17) until Nov. 17 is 31 days x 24 hours = 744 hours:

Air Conditioner is off in the closet at 0 watts x 744 hours = $    0.00
16 S3's at 370 watts each [5,920 watts] + 232 watts for 14" exhaust fan [6,152 watts used from Oct. 17 to Nov. 14 = 28 days] =  $359.52 at .08 per kWH
S4 @ 1400 watts from Nov. 14 to Nov. 17 = $6.21 at .08 per kWH
Total power costs from Oct. 17 to Nov. 17 = $365.73 at .08 per kWH  [My billing cycle ends on the 17th of every month]
Power costs each day with 1 S4 and 16 S3's - $365.73 divided by 30.3 average days each month = $12.07 per day power costs at .08 kWH

Nov. 17 to Nov. 30 = 13 days x $12.07 per day = $156.91 + $365.73 from the previous 30 days = $522.64 that will have been spent on power costs up till I add 3 more S4's @ $850.00 + $140 shipping = $990.00each.

I will have approximately 2.0 BTC to put towards the purchase of 3 S4's totaling $2,970.00 + $5,564.00 = $8,534.00 yet to be paid off.

16 S3's @ 7.4 Th/s = 4 S4's @ 8 Th/s = 15.4 Th/s

ALSO:

16 S3's @ 5,290 watts + 4 S4's @ 5,600 watts = 10,290 watts + 230 watts for 14 inch exhaust fan = 10,510 watts @ .08 kWH = $614.20 power costs per 30.3 day period.

With BTC @ $391.65 presently and the difficulty at the next projected level of 40,658,945,677 the profit after power costs per 30.3 day period = $1,610.39





Yes, the difficulty will go up every couple of weeks.  However, what if the price of bitcoin goes up as well?  The projections of professional analysts at https://whaleclub.jit.su/posts see BTC getting as high as $650.00 US by May or June.  They are projecting BTC to be approximately $425 over the next couple of days if it maintains it's bullish mood.  I'm showing one profitability chart at $391.65 with 40,658,945,677 difficulty (above) and the second profitability chart at $425.00 with the same projected next difficulty.  The projected payoff period is approximately 156 days.  However, this is an estimate.  BTC could go up significantly or down significantly.  I'm betting on up significantly.  If down, then down a little.



If one doubts this profitability based on this chart, lets look at it another way:



Revenue on Eligius Pool with 15.43 Th/s is 0.19597313 BTC per day [Look in top right hand corner].  I've mined their off and on and my 7.4 Th/s got a little better than their projected 0.09 per day. because of luck.  So, these stats are legitimate.

IF I mined at Eligius Pool with 15.43 Th/s and brought in a projected revenue of .19597313 BTC per day, that would be 5.93798584 BTC  [$2,325.61 w/BTC @ $391.65] if multiplied by 30.3 days on average in a month at present difficulty.

$2,325.61 - $614.20 power costs = $1,711.41 at present difficulty.  That is $88.00 less than the Profitability calculator over a 30.3 day period.  

I say the calculator is not a bad tool to determine projected profits and how long to pay off equipment.  If I was to stop right here and not add any more equipment, it would take 156 days to pay off POSSIBLY.  It could be less it could be more.  WHY?  Depends on how much difficulty goes up or down AND it depends on how much the price of BTC goes up or down.  

If difficulty increased 2% the next change and the price of bitcoin increased 6% from the previous difficulty change to the present difficulty change, we could take off 4% in days from our pay off length.  Of course this would be done each time the difficulty changes.  Of course, we would take add to the number of days till pay off if the percentage of the price of BTC was less than the percentage of the difficulty increase or decrease.  It's possible they could both decrease.  Yet, more days are tacked on to pay off period because the price of BTC [percentage wise] decreased more than the difficulty [percentage wise].

You can agree or disagree with my calculations.  That is fine.  Let the readers decide.

By the way,  I had completely different costs with 19.2 Th/s and lower difficulty factored in at the beginning of this forum.  Also, the price of BTC at the beginning of this forum was more than what it is now.  I'm using the calculations of what the price is NOW and what the NEXT projected difficulty will be according to Bitcoinwisdom.com.  So, the reason the pay off period is more than what was seen previously at the beginning of this forum is because the complete investment costs were not inputted and the price of BTC was more then than what it is now [2 days later].

Fair enough.  It's a free world on the internet.  For most anyways.

You are entitled to your opinion on this free internet forum.  Let others who read decide.

That break even period was for someone who stopped at the number of rigs I mentioned in the beginning of this forum.

I'm wanting much more that what was mentioned at the beginning of the forum.  So, yes, my break even will change over time.  I'm buying my rigs at a discount!  Meaning what I paid in my electric bill for kWH's to get the BTC needed for another unit is how much I actually paid for that new unit.

You do agree with that don't you?

After you answer that question, we can continue...

Using 4 exhaust Can Max Fan's @ 1786 CFM.  Two in each of the windows you see in the recreation room.

The recreation room is 12.5' x 25' x 8' = 2,500 Cubic Feet (CF).

4 Can Max Fan's @ 1786 CFM = 7,144 CFM

Trust me, they will be enough!

I already have one in the data/mining closet, which see:

In this 12.5' x 25' x 8' recreation room.  You see the data/mining closet at the back [which is where the garage is as well].  The black paint on the wall was where I painted iron spindles for my staircase.  In the middle of refurbishing my house I purchased as a refurbish.  It's a mess right now because it has been used for storage.  I'm putting plywood over the entire attic space.  most of this stuff will be in the attic soon.

All of that re-addressed here:


D. Number of Services and Meters:
1. The Company shall connect only one service drop or service lateral to a building or structure for each class of service except as permitted by the National Electrical Code.
2. Only one watt-hour meter shall be installed per Customer per class of service except as explained in item #1 above. IN NO CASE SHALL METER READINGS OF TWO OR MORE WATT-HOUR METERS BE COMBINED FOR BILLING PURPOSES.

This means they would replace the existing with what I need; as well as the gauge wire.


F. Metering Installations Where The Service Rating Is Greater Than 225 Amperes
1. On Single Phase service: Where the service ampacity rating is greater than 225 amperes, but not over 400 amperes, a self contained class 320 ampere meter socket furnished by the Company shall be used on 1-Phase 120/240 or 120/208 volt service. When the service ampacity rating is greater than 400 amperes, but not exceeding 600 amperes, the preferred method of metering is a transocket. When the service ampacity is greater than 600 amperes, current transformers shall be used.
2. On 3 Phase service: When service ampacity is greater than 225 amperes and less than 600 amperes, the preferred method of metering is a transocket. The 3-Phase transocket is provided with a 600 MCM dual rated two port non-rotational connector on line and load side of the transocket. When the wire size to be used is larger than the capacity of the connectors provided by the Company, a current transformer installation shall be used rather than the transocket. When the service ampacity is greater than 600 amperes, current transformers shall be used. 4w 3ph Class 320 amp self contained services are not allowed by the Company.

I don't see the power company installing a current transformer in my yard to feed my house.  There is a current transformer across the street in a locked metal cabinet on the ground.  All of the utilities in my neighborhood are buried.  I know a current transformer doesn't come cheap; with the labor and costs.  The power company is already going to want to know if I'm running a business out of my home when I ask for a 600 AMP service and meter upgrade to the house.  I'm sure I will need to show them my rigs to show them I'm not running a business, this is for myself [an individual] as an investment and not a business.  Cost per kWH for a business is almost twice the cost for a residence.

I'm limited pretty much to 600 AMPS.



I will replace 6 of the 8 120V/20A circuits in my existing 200 AMP breaker panel I installed for my present set up.  They will be replaced with three (3) 240V/30A circuits.  However, I will only have four (4) S4's on each one of these instead of five (5).  Why?  Because I do not want to trip the 200 AMP Main breaker when I'm cooking, the dryer is on and the AC kicks on during the summertime.  

I'm going to just use 70.2 AMPS out of my present 200 AMPS for rigs.  Once I approach using that 70.2 AMPS as I add more rigs, it will be time to call the power company.  If I try to add more, I know the Main Breaker will risk tripping.

These 3 240V/30A circuits will have 3 240V/30A metered PDU's:

16 S3's I presently have will be on PDU #1:  Each of my S3's burn 370 watts on average [with PSU] at the wall x 16 S3's = 5,680 watts of the 7,200 watts allowed for this circuit. [23.6 AMPS]

4 S4's on PDU #2:  Each S4 burns 1400 watts on average at the wall x 4 = 5,600 watts of the 7,200 watts allowed for each of the two 240V/30A circuits.  [46.6 AMPS]

This brings the total AMPS used to 70.2 AMPS with 90 AMP's total in Breakers.  So, don't think I'm using the full 90 AMPS.

I can install 600 AMP Panel to the left of my present 200 AMP panel if the Power Company will give me 600 AMP service.  I believe they will.  I would pay an electrician to handle making my existing 200 AMP panel a sub panel off of the 600 AMP panel BUT the 600 AMP panel would have 16 30 AMP breakers in it.  Does that mean I will use every single amp in each of those 30 AMP breakers?  No!  I would burn 5,600 watts [23.3 AMPS] of each one of those 30 AMP [7,200 watt] breakers.  5,600 watts x 16 = 89,600 watts or 373.3 AMPS.  All of this inspected of course.  I would even have the inspector inspect the wiring going to the recreation room for my set up in there.  This way I KNOW I'm still covered with my home owners insurance.  

All of my light bulbs in the house are LED except for one.  It is a lamp with a 3 position switch to choose 3 different brightnesses.  All of my lights outside of the house are LED.  Even my flood lights outside are LED.

16 outlets x 4 S4's = 65 S4's x 2 Th/s = 130 Th/s

So, on the 200 AMP existing panel I will have 8 S4's and 16 S3's working off three 240V/30A PDU's.  Those 16 S3's may be replaced with 4 S4's in the future.  With the S3's, that would be 7.4 Th/s + 16 Th/s (S4's) = 23.4 Th/s.

Potentially 153.4 Th/s total.

The first 23.4 Th/s may take 6 to 12 months.  It depends on how the price of BTC does.  I'm not saying I will add a 600 AMP service meter and Main Panel in the next 6 to 12 months by no means.  I wish I could.  It depends on the amount of work I get next year and the price of Bitcoin.  I'm betting it goes to the moon soon.  Especially, by the middle of 2015.

As for my wife, 3 year old and myself, we will be just fine no matter what.  I'm not sure how many watts max the power company will let me have at the house.  However, I'm hoping it will be 600 like they say in their rules and specifications.  If they are getting paid for it; it's been inspected and approved; why not let me have it?

As far as I'm concerned, I'll increase the size of my farm and everyone else can leave theirs right where it is!

Then, when BTC goes up to $600 or more, I'll be laughing all the way to the bank while everyone else who didn't increase the size of their farm wishes they had.

according to your response; why should anyone bother mining?  LOL

Read my responses at the bottom of this page and the next page in this forum.

That's what I thought.  So, not BITMAIN...

Who promised it?

WOW, these rigs can maintain operation with a lot of heat.

I was thinking about the longevity of equipment and the affected hash rate of the equipment.  I should have been more specific.  I've seen pics on youtube of rigs laying in a pile on the ground at large farms in China that I assumed had went out of service.  The building they were in appeared to be poorly cooled with large doors open to the outside.  So, I assumed the rigs would burn out much sooner than normal with the temperature too high for long periods of time.

Curious if anyone has had enough experience with S1 rigs since they came out to know if the temp mattered that much.  It used to be that S1's were the rig to have.  It may be that not enough time has elapsed to even know the answer to my speculation regarding the S1 even.  Don't know...

Thank you for your input!

Anyone else want to ring in?
