No problems here as well. I would prefer it actually.
(As long as we have pay per post instead of Fixed rates).

If we get bot working again and funded every week.  I like weekly just as it's easy. 

If pay is same and amount of posts allowed is same monthly would work.  But I don't think it will fix current problem, I think once bot is fixed and is always funded weekly is just as easy ( or should be). 

And I'm in same boat with missing 2 weeks of payments so far.

Considering to buy, you can buy it through localbitcoins site. It has got good trading network along with trust rate which makes your buying easy. Also for storing Blockchain is good than other wallets.

Using blockchain is not safe. Keeping bitcoins in online third party services is not safe.

Yes your buying option is good. You can use offline wallets like Ethereum to increase the safety of your bitcoins.

Also hardware wallets are a really good options if you need use of coins.  It allows you to be protected even if used on a compromised computer on most.  Such as Trezor it is really a great tool.

I still see future where more and more use hardware wallets.

yes, trezor is good but it also is expensive. so it makes it not for everybody.

people like me who are just planning on holding their bitcoin in a cold storage, add to it from time to time and also have the option to sell if the price went up should use other offline wallets especially if you don't have like 1000BTC

Expensive all depends on how much you are storing.... I don't look at 100 dollars as a expensive item to keep my active wallet secure.  If you were holding a single bitcoin then yes that would be considered expensive.

So all relative to how many coins you will be using it to secure.

Good and convenient I see as two different wallets.  Most convenient wallet?  Going to be a hot wallet likely blockchain.info (due to popularity).   

Best wallet.... I see as hardware wallet.  They are easy to use and also very secure.  I think you should make security a bigger deal then convenient.

Also let us know which Batch of S7 you have and which version of firmware did you flash into it?

Rich

It should be batch 7 it was only one that was 5.06 Th/s.  And was actually only one rated over 5, so it should be a batch 7.

We really should let this thread die.   Someone took smartminer and photoshopped it.... not a suprise.

The sad thing is chances are someone or ones will fall for it.  I cannot explain it but these keep poping up due to they make profit again is sad.  This product does not deserve to keep the name high up in hardware section.  And all the bumps do this.
1786  Bitcoin / Hardware / Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH on: March 04, 2016, 10:06:38 PM
i bought recently my first miner the cost =779.86doll for the miner  140doll for the psu 99.5 for shiping .total 1119 doll+ taxes here in greece 360 € and the miner gives me each day 0.02 bitcoin so i have to wait over 7 months to get my money back not including electricity. is that right or have i done something wrong?

$780 + $140 + $100 = $1020

But still, you spent $1400+ on something assuming it would make you money without checking the math yourself?

Maybe he will luck out coins go to 600 in the next month and he can sell the miner at break even price.


The good thing is if you get a good PSU you can use it multiple asic generations.  So you literally can plug new gear into old gear spots.  That's what I plan on doing with my spots of last gen gear.  I did not sell PSU's as I re-use them.

Also you can always sell PSU at end if you are not going to re-use.  They keep a decent amount of value if a quality PSU.
1787  Bitcoin / Mining speculation / Re: 21 cents per kw, Any way to mine? on: March 04, 2016, 10:03:28 PM
The only profitable coin to mine at present is the Ethereum. But it is with GPU not any ASIC. If the price drops, it will not be profitable.

it dropped already i assume it's not proftibale anymore, since even without the drop the diff started to increase fast now with the drop it's done

The price of Ethereum is still high, around $5-6. So it is still profitable. If it drops to $3, it will not be profitable.

That is great... but long term GPU mining is still not alive with electricity price, and GPU prices.  Will you ROI on your GPU's?

Unless there is a chance of ROI I don't consider it profitable mining.  Just mining more then electricity.... is not enough for me.

If you can earn 20% profit each year as a business, you will be very happy. The problem with mining is that it is not sustainable.

This is not a regular business in mining terms 1 year is a LONG time.   Gear can change a lot within a single year, so I would argue a sucessful buisness needs to pull profit quicker, or sell machines off and get roi quicker.

Selling machines has helped by bottom line.  I have normal electricity price nothing secial.  So I mine as long as I can being profitable, keeping a eye on prices of gear on secondary markets.  I recently sold all last gen gear.... I invested in coins.  And eventually it will go back into machines.

I think the reason why the difficulty stayed the same is because if you look at ETH hashrate, it went up by 300,000MHs, which is about 15,000 280X, each 280X uses about 175 Watts so about 2,625,000 Watts which at 0.50W/GHS is about 5,250,000 GHS.

So its accounts for the 5PH/s loss in BTC hashrate.

well we are - 3.49%  that is about 38.39 ph

there are multiple factors

ETH grew
PPC grew

Weather is warmer not then the jan 22 to feb 14 runup

Unknowns------ Ghost cities in China with ghost mining

A chinese farm did get busted stealing power.

Someone had a 3 week 1 cent power contract and ran  older gear for the Jan 22 feb 14 time solt.

Then turned the gear down

Just don't know whats up.

good luck to the close ones.

ETH and PPC are a good point.   If we could get some alt coins that truly bring profit and ROI on machines.... would be good as miners to have more the just BTC to mine profitably.

I don't believe the one about stealing electricity.  Just someone saying they saw a tweet... seems to good to be true.  Also I think they would get gear out of there quick and to another location.  So would be temporary.

I still have a lot more questions then anwsers to go from 13+ to this... still just don't get it.
1789  Bitcoin / Mining speculation / Re: What are miners doing with their profits? on: March 04, 2016, 09:56:40 PM
When I have a significant amount of profit, for the near term it will probably go into more of whatever hardware is actually generating a profit for me.

 9-)


 I strongly suspect the big mines aren't as profitable as many folks assume - they've been hit by diff increases like everyone else, they just tended to get hardware cheaper so they could RoI it somewhat sooner.

Yes but look at the ones owned by Bitmain.  Do you think they pay near per unit as we do? I highly doubt it.   Also electricity it no doubt is a few cent's.   How many .... hard to saw.    But would bot surprise me 1-2 cents.

I think ones linked to manufacture are most profitable.  Second I think the big mega mines, again they are getting discounts due to amount they buy.   And again very cheap electricity.   

There has to be a lot of profit or they would not continue to re-invest.
1790  Bitcoin / Mining speculation / Re: Massive amount of S4 watercooled on eBay on: March 04, 2016, 09:52:40 PM
Maybe when he says 220 pieces he just means boards, If i remember correctly the S4 had 4 boards in each box.

220 pieces is only 55 complete boxes...

I read it as 220 units.  If it waas meaning boards I think he would have had to put hashing boards (and would be a weird way to sell by board number).

That being said I cant imagine anyone paying much for these as a group.  I think they would have done better selling 1 at a time.... but looks like they are in a hurry.

1792  Bitcoin / Mining support / Re: Need help choosing psu for my antminer s7 on: March 04, 2016, 04:12:13 AM
First off I purchased the EVGA SuperNOVA 1300w psu thinking its is enough. This is how it is setup https://imgur.com/Eig0vG4  I have lots of those "vga" 8 pin to 6+2 pin connectors that will connect to my miner. Can I use these? Also is it safe to go from 8 pin to 6 pin? Also some of those 8 pin give 2 6+2 pin giving me a total of 8 possible 6 pin connections to my miner... I just want to not risk burning my miner because I gave it too much power on one pci-e

If this doesn't work, I will buy 2 separate power supplies because I only have an 120v/15amp outlet. So what power supplies do I need to to run the miner?


Keep the evga 1300 run it on 2 boards use all six cables

and then get a 760 watt psu  run 1 board/blade and the controller.

if you want I have a quality seasonic  760 watt platinum used good price.


http://www.amazon.com/Seasonic-SS-760XP2-Platinum/dp/B009VV55TA/ref=sr_1_4?

some will tell you the evga 1300  can do the trick and on the batch 1 or batch they worked you could split cables.

if you have a batch 8 or newer do it right.  I can sell the platinum  seasonic to you cheap. with 4 pcie connectors

you could add a new evga 750 watt http://www.amazon.com/EVGA-SuperNOVA-Crossfire-Warranty-220-G2-0750-XR/dp/B00IKDETOW/ref=sr_1_5?


this would do 1 blade and the controller

Well my miner is from batch 8, and I don't want to spent more money than I already did for this psu. I can return mine and buy a 850 watt psu and buy your 760 platnuim one. Would that be fine?

I don't know about the 850.... "Power Consumption: 1293W + 10% (at the wall, with APW3, 93% efficiency, 25C ambient temp)".  It seems like you are wanting to push a PSU hard.... not sure why.

Keep the EVGA 1300 its a good PSU.  You can sell it after if you need to when your finnaly done mining with it.  And get the one phil is selling.   I don't see reason to go to 850 to power 2 hashing modules... and try to push the psu.
1793  Bitcoin / Mining support / Re: Help trouble shooting Antminer S7 5.06TH on: March 04, 2016, 04:04:55 AM
You fucked yourself.  I am the guy that begged people to never run a bitmaintech firmware.

many reason and stories abound.

 basically you are bricked.

first is that a batch 5,6,7,8

bitmaintech did 11 batches so far and 1,2,3  will plave with each other as long as you di not upgrade firmware.


if you are and older batch like a six  look for a batch six controller in the market place.

so you need to know your batch number and then ask around for help.

the 1,2,3   and the 9,10,11   are two sets   then middle batches vary.    any they started striping the controllers  down so   you really need to know what one you have.


I have a batch 2  the controller allows be to attach a second s-7's set of boards but only from the 1,2,3 batches.



I pushed not to do it on any that did not run off SD cards.  S4's and C1's ran off sd card....  bad flash reflash the sd card simple and nice.  But cheapness made ones run without sd cards.  Removes your ability to fix a brick quickly.  Ever since I bricked a S3 I have mentioned many times I don't update unless big flaw.  Only one that met this was some S3 reset did not work.... so big flaw need to update.  Been a LONG time since a good reason.

On S7 if works... don't touch firmware.  The hard part OP is you need to try to go back to working firmware or do another flash... to see if it is a bad flash.  But problem is your power off's.  If you get a single power off during your re-flashing you have a brick.  So your in a hard spot.  Might look at re-ordering a BBB board for your batch if truly is F'ed and count it as lesson learned.
1794  Bitcoin / Hardware / Re: Why do some S3's overclock and some dont? on: March 04, 2016, 04:00:16 AM
Hi guys,

Just a curiousity question really. I have an S3 and an S3+ and the S3+ is overclocked to 250freq and has been since I got it. Runs fine only gets the occasional error on one chip every two weeks which a reboot sorts out. The S3 on the other hand wont take even the next freq up without throwing chips left right a centre or not powering a whole board.

Now to my question, why are they behaving differently? I know they are made at different times, and are technically different models, but has anyone tracked down or does anyone know why they behave so differently to overclocking?

Thanks.

the +  are better.

batch 1 and batch 2 were bad models they ran at freq 218 and freq 212. the did not do well

Batch 1 was bad enough everyone got partial refund.  Some ran up to spec but a lot did not.  To avoid this phil is right buy a + model and you should not have to worry about the really bad ones.

But S3's had a personality it seemed to me.  I always had some better then others and fined tuned each one.  But get a + if at alll an option over normal.
1795  Bitcoin / Mining speculation / Re: What are miners doing with their profits? on: March 04, 2016, 03:55:29 AM

They interviewed the wrong ones then... these mega mines are making huge profit's.  Cheap electricity and a some linked to makers of machines.... that leads to massive profits.

It's common sense these big mines are the ones doing the most dumping.  And they can keep some but they are a far bigger percent of machines hashing then the home/hobby miner.

Home/hobby miners are small portion of hash at this point.

Well the free market will sort them out.

If they dump now because they are impatient, and the price goes up later, they miss out on big profits. So maybe they will save more next time.

But at the same time by dumping now, they let many newbies buy bitcoins cheap now, rather than buy later more expensive.

You say that but really there is nothing that makes right now that cheap.  It is current price.   Cheap... look back 220's through there now that was cheap. 6 months or so ago... now looks cheap.  Right now is market price.

So yes we hope it goes up and speculate it hopefully.  But there is no guarantee's in this game at all.

1797  Bitcoin / Mining speculation / Re: Massive amount of S4 watercooled on eBay on: March 04, 2016, 03:48:47 AM
I don't believe a lot of it.  They say " We have Bitmain Antminer miners 220pcs new in box."  For a S4 to still be new in box at this point and 220 of them for this amount of time seems like a very unlikely thing.

The water cooling job I don't think was to great they say "This also comes with 150pcs S4 miners already converted with water cooling with water blocks, but many of them don't work well so please treat them as junk."   That tells me you will recieve them in parts... and treat as junk 150 unit's that is a issue.

Someone is trying to get out of the game with previous gen gear.... but I think they waited to late with shipping costs.  And considering it sounds like the water cooled ones are considered junk to them.

I have a GTX 750ti that I have been running on Nicehash for the last two months with profitable results, If your electricity is truly $.02-.05/kWh you will make some profits by way of BTC, but based on my math your ROI will not be nearly as fast as running S7's in the current market. My *personal* advice would be to invest in used/new asic equipment if you're thinking about investing anything. As always, do your diligence on your particular situation.

I don't know why threads like this keep continuing.  GPU/CPU day's of ROI are OVER.  Yes you might make a profit over electricity if you have low electricity price.  But you will not be in ROI and pay off a nice CPU/GPU.

Everyone really is a few years to late.  The 90 day roi on that equipment just does not happen anymore like once did.
1799  Bitcoin / Mining speculation / Re: Diff thread Feb 19 to Mar 3? picks are closed.... prize = 0.2 btc on: March 03, 2016, 08:26:08 PM
I really hope I win. Not because of the prize, and not because our cats love fishy treats.

I want to win because my pick is the largest negative value.

Of course I'd be just as happy if I lose because the difficulty goes down even more than our cats' guess.

If you win it's kinda a win for all miners.  To get a negative in that teritory would be great.  I would love to see it after how difficulty has been lately.

I do wonder what's causing it though.  I wish we knew this part.  What caused us to not surge this  period and go into negative... and also how long term is this going to happen.

I have no idea WTF  but it is very nice to see.

WTF really is a good question.   Price is 416 so dropped... but I think don't think that causes stop from big jumps in difficulty to negative.   I can think of a few ideas.... but none of them make sense.

People turning off gear... I don't see it as I think almost all will have info-structure they will put in new gear when old gear is done.  There is still a lot of A1's I suspect plugged in at very cheap electricity, some day they will come off but is it happening now? I don't know.

Big data centers buying gear to get last roi before having? Again I'm not sure... I can see it happening.  A lot of these I would think are in talks with Bitfury, and that scares me.  I keep thinking one day we will see news of bitfury shipping gear..... and that I think will make difficulty jump a good amount.  Again I don't know.

I really do want to know what is going on though.  Just not enough facts right now to prove anything.
