Greece says if they leave then expect Italy will soon follow due to their own debt situation.

I'm not clear on the EU economic bonds versus their political bonds.  Say Greece pulls out then Italy, will border crossing posts requiring passports go up along the Italian border?

More of Bitcoin owner concern, will Greek and Italian banks halt withdrawals?  Will Bitcoin benefit or has its devaluation since December 2013 precluded it as a 'safer' haven than Greek or Italian banks?

Hoping an active miner group sales person would branch out as fewer miners are getting sold. 

Getting a solar system up and running exclusively for mining and not connected to the power grid would be a start to eventually getting it onto the grid.

Living in landscape that's essentially a bowl having sides on the east, south and west is a bummer but if I cut down and sell the hardwood clearing most of the center I could put a sizable solar farm on my north side and the wood sale might pay a good chunk of cash. 

Integrating solar energy with the power utility is a bear and they don't like it down here in rural Georgia, it cutting into their profits and all.  But, driving my 12vdc miners would seem ideal.  That with 12 volt marine batteries would work immediately and could be done without involving the power utility.  As it is my electric bill is 2½ times what it was this time in 2012.

So, would group buys of solar panels and marine batteries be allowed in this forum?

This blockchain had been a bear to keep current.  The Vaio laptop was low on memory and kept crashing until I found that I hadn't been mounting my swap file.  Since mounting my swap file there have been no more crashes.

I'll take your advice about changing my fee entry on my Bitcoin-QT.  It takes work to keep these running and for what I ask, looking at the 0.0616 fee.

So, I'm running two Bitcoin-QT blockchains and have never seen any transaction fee credited for running these.  How do I get credit for maintaining these?

Oh, I see:
"While running Bitcoin-qt it is true you are contributing to the Bitcoin network, but only in the sense that other peers can now download the blockchain using your bandwidth. There are no transaction fees sent to anyone that is not mining. Mining is the process which helps the network transact and thus sending balances from one account to another. " from http://bitcoin.stackexchange.com/questions/21668/can-i-earn-transaction-fees-by-running-as-a-full-node-verifying-transactions-b

I suppose I felt burned after a stupid mistake.  Deciding to sell 10btc that I had been holding on to for so long while watching it lose value over the years, and knowing that Coinbase Exchange is allowing no fee buying and selling for a month, I made the mistake of thinking that there'd be a no fee transaction on Coinbase proper and ended up paying a 10% fee for selling on Coinbase instead of Coinbase Exchange.  Stupid mistake.

Bitcoin-QT 4.6.2

No.  Did Coinbase increase the fee for accepting bitcoins?  Dust.  I see.  These bitcoins were mostly mined in 2013 & 2014 and paid out at ~.1 btc while the lower charged send was mined in 2015 and paid out at .3btc from another wallet.  But still, I sent 10btc from *this* wallet to Coinbase on 1/21/15 and was charged a .0012 network fee.   

I maintain two copies of the blockchain, two running instances of bitcoin-qt.  The other day I sent 10.00 btc to Coinbase and was informed by bitcoin-qt that there would be a .0012 transaction free.  Fine.  Today I went to send roughly 9 btc and was told the fee was over 0.06 btc?  I don't understand the increase.

Okay, there are horse race rags selling data on horses in upcoming races and giving odds.  There are websites selling advice on buying and selling stocks and bonds.

I see the list in the first post of this forum but these give stats not advice.

What is the subscription website with the best track record regarding short term and medium term predictions on Bitcoin buying and selling that might be based on inflection points, slope, volume and other criteria I can only guess at?

Thanks.

I see from this Aug. 2014 article that another building was being added.  Has that come online?  What is the expectation of hashpower increase in China by mid-2015?  http://www.thecoinsman.com/2014/08/bitcoin/inside-one-worlds-largest-bitcoin-mines/

Are any more large farm additions anywhere in the world visibly on the horizon?

Slow day on the pool and I decided to move the C1 to the back room.  But I thought I'd open it up and take a first inside look first and check the torque on the heatsink screws.  Disappointment.  They've used only one screw where the S3's had a pair of screws.  Worse is that a large number of the screws that are there are stripped in their aluminum heatsink holes!

The screw pair has only one side tapped the other is tapped from the far side.  I realize that.  Still, thru tapping instead of blind tapping might have allowed two shorter screws to be used.  But then again, they do have that stripping screw holes problem.  Threaded cast aluminum is always touchy to torque.

I wonder if anyone has tried cooking an Antminer board.  I'm not sure if it was on this C1 thread or the S3 thread but someone posted a photo of an IC blown off the board along side a missing capacitor.  (Had been on the S3 thread but photos removed by poster.)  Where the IC was gone you can see the underside ground plane having a grid of thru holes to the ground plane of the other side of the PCB.  A common cause of IC failure is when that ground plane under the IC isn't soldered sufficiently and a small gap exists.  Cooking a PCB in an oven reflows the solder and often repairs that ground plane soldering.  On the other hand some ASICs just perform less well than others, e.g. not having a full complement of functioning engines which wouldn't be helped at all by cooking the PCB.  BFL was notorious for vetting the ASICs and routing products containing poorly performing ASICs to customers who didn't pay a surcharge.  If you didn't pay the surcharge you'd likely get a miner that ran almost 10% under specs.  Cooking wouldn't help those.

Regarding the reset button, what worked on an S3 was to shut it down 60 seconds, fire up while mashing the reset REPEATEDLY and quickly for about 30 seconds then a long hold down then release.

Odd.  Today my wattage rose from 845 yesterday, includes pump, to 880 watts.  Also this evening my hashrate was down around 950.  Radiator is in the window drawing in 25.4°F air.  I tried the GUI reboot for the first time.  The unit wattage dropped to 220 watts (generally 145 watts when starting cold) then picked up to ~500 watts.  The GUI said I was only getting about 500GH/s and no temperature was registering.  After a minute of this I shut it down (sent halt from ssh) then killed power, let sit for 60 seconds and reapplied power.  Started at 145 watts then up to 820 watts and after 8 minutes getting 968GH/s(avg) and rising.  Temperatures are still reading 0 on all 4 chains.  Disconnecting a fan....

--------------------------

21 minutes: 1,061.90GH/s(5s), 1,000.20GH/s(avg), temps: 20 22 20 22 Fan 1,200, 831 watts

I have two S3's and if they run long enough one comes up with an "-" and the other an "x".  Rebooting doesn't clear these but if I shut down and let sit for a minute then restart both, both come up all"o"'s.  Always the same ASIC on each.  It can't be temperature as with windows open the room was 42°.

Curiosity.  Anyone tried BFGMiner on a C1 or even on an S3? ...never mind, I see luke.jr answered this previously:

"AntMiner S* products will not be supported until Bitmain (the company producing them) makes significant changes to their corporate policy. Not only have they failed to provide us with sample units (since the S1), but their products are closed source in violation of the GPL license terms of Linux, and would require extensive kernel reverse engineering effort."

Anyone experimented with trying cgminer for the S3 on the C1?

Thanks.

Stock batch 2 C1, standard settings.  I don't want overclocking.  I want my miners to run dependably at rated speed with the option to lower settings for reduced power when the btc value gets so low I almost need to stop.

And thank you for the "225Mhz @0725 0.758 W/GH".

I haven't opened the C1 yet.  I understand it has an SD card similar to a BBB?  I may have rebooted since first changing the password from the linux command line after ssh'ing in.  Perhaps that password change isn't saved to the compressed files on the card.  I would think this is a security fault if the root password change remains for the GUI login but reverts back to admin for the ssh login.

I think the future was shown when KnC priced their Neptune too high then sold those at a discount to family owning a miner farm selling shares in a low electric cost low temperature part of the world.  They effectively said don't buy our Bitcoin miners but we'll sell you shares in our farm.  It's the don't buy our Bitcoin miners that's the key.  They did start selling script miners for alt coins.  They then went on to dump the Bitcoins they owned onto the market and it's pretty much been a decline in value ever since, tho I note BTC value went up toward the end of the 2014 fiscal year.

The effect is to kill home mining.  What they may be doing, having a very efficient mining farm, low energy cost and cold climate,  is trying to drive less efficient mining gear into running at a loss, shutting those down.  That might mean dropping hashrate eventually.  As their share of the daily mined BTC increases they'll continue to dump the BTC for hard cash.  So, even tho they take a larger share of the market the price won't rise as they'll still be dumping BTC.

I really should have dumped my bitcoin horde.  Now that the electric bill is taking a larger chunk out of my social security retirement check I'm going to have to sell mined BTC this year.  Selling my mined bitcoin this year will make it clear when I start mining at a loss.  Still keeping my horde of BTC and weeping as its value declines.  I only wish Karpeles hadn't screwed the pooch and caused such a loss of confidence in Bitcoin by the general public.
