Bitcoin is going to crash, big time.
|
|
|
|

Unlike the policy of Bitmain, they starting pre-orders now.
Any thoughts about this?
Paying 1.3 BTC pre-order while the bitcoin is taking a dive (slow but certain) can leave you in 3 months with a miner devaluated to .5 BTC without even mining a bit.
We have all see it go wrong with Black Arrow.

Is there any way to create a signature and change your settings if you are using a blockchain wallet. I am sure many people have a hard time with this. Any help you can give is appreciated.
Let me know if you need more help What is the benefit of this action? Benefit of online wallet or benefit of signing messages? Oh sorry, the signing of messages |

vardiff can really mess with your reported hash rate, it's all about accepted shares. I've been on some pools with vardiff that set my difficulty to 12000+ and it freaked out my miners and upped my stale rate because my miners could not keep up with the switching of coins in the multipool. There are many factors that can change your reported hash rate but it's not likely that the pool is changing your hashrate, if the difficulty is set to a specific number like 512 for example then your reported hashrate should level out. It will still go up and down depending on your accepted shares.
Read the above post, I agree that power/heat can have a big effect on miner performance. I have mine connected to a battery backup that reports the wattage, when when my miners are having issues the wattage goes down or fluctuates and I have to restart my rig. You can buy a meter to plug your miners into, that might help determine if there is a power issue and also help calculate your power bill. lol
I got a power meter on my miners since day one, don't want get a surprise when the bill comes in :-) My 3 S1's + 2 klondikies are doing about 1200-1300 Watt And you have to subs-tract the power costs from your BTC earning else you would fool yourself big time! Also you have to keep to calculate the moment the BTC rate drops around the power consumption you have to unplug your miners from the wall, there will be a moment your miner goes down the shredder. |

Yea if the pool isn't sending you work fast enough. Also check the difficulty. I've never used Slush so I don't know their difficulty but 128 is optimal for 180 GH/s. 64 or 32 probably won't hurt too much but if you're getting difficulty 1 shares I could see that slowing you down. In Antminer S1's you can see difficulty under miner status in the "diff" column under pools.
What pool would you recommend? I just placed one miner @ BTC Guild, 2 left in the slush pool |

I am mining at Slush, just got my 3rd S1 online, but I see that my overall Ghs is slowing down to 135 Gh/s while they are default at 180 GH/s each.
Can anyone explain this?
So can a pool operator influence your miner speed in any way???
make sure your PSU's are sized right 72A @ 12Volt on each miner enough? :-) :-) |

Become a exchanger yourself ?

Hi,
I was wondering when you buy a miner from Bitmain is china does the custom charge duties on it?
Normaly when sending a package from foreign countries there has to be a invoice on the outside showing the value of the product.
But when you pay in bitcoins and the value on the invoice is in bitcoins they should not be legally entitled to raise tax on it because bitcoin is not an official currency in most countries.
People who previous ordered miners and paid them in bitcoins, how did this work out??
I live in the Netherlands.

Invest if possible in development or producing companies that make and sell BTC hardware,.....They are or become the big BTC millionairs, the miners are the poor bastards at the end  |

Hi,
I blew up 2 USB antminers U1 the defective part on the stick is marked as U3 on the print the part itself has the sign 5038 (or 503B).
Can anyone tell me what electronic part this is?
|

Can you use U1 and U2 antminers in the same rig, or is it going to conflict.
Currently I have 2 U1 and 2 U2 miners working in one hub together but each time I start up 1 of the 4 miners is not hashing higher than 300Mh/s the other 3 around 2 GH/s

I restarted the "rig"  ,and i let the miners cool the metalplate on a servercase. I clock them now on 2Gh ,and they ran fine around 2Gh the past 24 hrs. The worker shows a avg of 4Gh So also extra cooling seems to contribute a lot |

Hi,
I have a Raspberry running on cgminer with 2 Antminers U1.
Each Antminer reports about 2 Gh/s speed, so that's ok.
However pooling on bitcoinCZ the site reports avg 1461 Mh/s that is less than 1 miner does.
Both miners run on 1 worker, should you configure each miner on a worker?
How do i get "up to speed" ?
|
|
|

hmmm, yes they do get v warm when running at correct speed.
Does the Antminer run ok on say a normal windows pc? Or do you have a 2nd unit to test to see if its duff or not?
Other than that i would unplug all devices, completely turn off, then back on insert only the antminer and try.
if not go back though and perhaps re-do all steps. (Should be fairly quick at doing these by now! i know i am..lol)
just one more thing to check, there may be somthing wrong in your start line! somthing as simple as a space in the wrong place, or only 1 - instead of 2 --. if the freq and bauds are not sent correctly then i think it goes to a low default setting.
sudo ./cgminer.exe --bmsc-options 115200:20 -o stratum.bitcoin.cz:3333 -u oldiesel.worker1 -p x --bmsc-freq 0981
drop the .exe! (this is only for windows)
You don't make this up! ;-( I ran the install again, in the right and complete order. still low speeds,...damn. Checking the USB hub powersupply,......Guess what,....DEAD!! So after all the supply of the PI was feeding it. Hooked on a universal net adapter ,both Ants running now on speed. |

do you have them in a Powered hub? as the Pi by itself cannot supply enough juice to run any miners!
Yep, they run in a powered hub, 2Amps. But they not even get warm. Now i realize what possibly went wrong, i didn't run the part: If you are using a Raspberry Pi do the following: sudo nano /boot/cmdline.txt Add the following code at the end of the first line (on the same line as the other text) slub_debug=FP I did it after all, do this mean i have to repeat the following steps? Or do a complete re-install? |

Hi,
I have a Raspberry Pi and 2 Antminer U1
I followed up all the steps Sweaving posted here, and my stuff is running
Started up with sudo ./cgminer.exe --bmsc-options 115200:20 -o stratum.bitcoin.cz:3333 -u oldiesel.worker1 -p x --bmsc-freq 0981
As you see I started it op for 2.0Gh/s
But i seems to have difficulties "Getting up to speed"
They run @ 200 Mh/s max each,...what do i need to optimize?
