If you bought from eyeboot, it's a green stick. Note that the board it's build on is green. The ones in Europe are made with a black board.
Have you tried adjusting the voltage a bit higher and replugging it?
Yes, i also tried to adjust the voltage as mentioned in page 2 but without any luck. I turned to 1/8 clockwise, unplug and wait 2 secs and plug again. I also tried 1/4 turn, unplg and wait 2 secs and plug again. Nothing has changed, problem still remains. >< Pls advise and help. Consider plugging them one at a time into a different computer, if available, to see if they behave the same. |

You can use vanitygen with the full prefix to get a bitcoin private key but you will need to modify it a bit to not abort and tell you your being hilarious. https://bitcointalk.org/index.php?topic=25804.0The sun will stop burning while you are less than 0.000001% done. |

I'll join in the fun and guestimate at the bitcoin reward value slot.
+12.5 = vh

There is no reason what-so-ever for the words AMU to show up in your question if you follow the instruction in the OP of this thread.
Toss out or set aside the cgminer binaries you have. Re-read the first post.

As soon as you attempt to make any ASIC resistance changes to bitcoin, you will no longer be mining bitcoin.
ASIC is here to stay. The bitcoin network will adjust to allow about one block solve every ten minutes.
Selfish or Unselfish miners does not change that.
Fast or slow SHA processing power does not change that.
One miner or One billion miner does not change that.
Extreme desire to want to force mining with a CPU or GPU will trigger a new coin into existence as it has in the past.

If the point of the post is to describe a secure way to generate and protect private keys, your example is well laid out.
If you want to generate a tip list to share the awesome bitcoin experience with friends and family, just skip it and get a few hardware wallet like the Trezor / Ledger Nano S for yourself and them for Christmas. It's a decent middle ground.

This is an interesting question. To even visualize it somewhat properly I started by ramping this forward and imagining that bitcoin mining reward drops to 1.5 BTC/Block next week. Will bitcoin value jump to $500,000 or drop to $1?
Too many variables to account for, but I'm comfortable to guess it's not $500,000.
Even with 13 more years of variables to play out, still not going to say $500,000 per BTC.
So I'm going with never ( or more specifically not by 2030 ).

You can post. It just won't show. Someone further along in rank may quote you to make it appear if it's relevant.

While there is no direct relation, there is a cost to mining. If value hit "rock bottom", hashing rate will drop and difficulty will drop to maintain an average of one block every ten minutes.

what do you mean by "reindex", and how do I know that it is the correct wallet.dat?
There are two useful options you can add onto the command line as a startup parameter. -rescan Cross references all the addresses in your wallet with the block chain and adds missing transactions syncing (balance) with your wallet.dat. -reindex Rebuild the chain state and block index, syncing bitcoin core with the network. If you see your old addresses in the software then you have the correct wallet. Stop and manually start bitcoin core with both options, wait some more, and ideally to return to normal operations. |

There is limited space on the block, so not all transactions (tx) waiting in the mempool can be placed into the block. Accelerators are simply a commitment by the corresponding pool to include the requested tx over all other tx in the next block they find.
So I am guessing they would pay more? And is there more than one mempool? Some yes. Some offer it for free but with a limited quota per hour. There is one mempool per node in the network. They should be similar, but not always identical. Each transactions also has a slot for optional fees to be collected by the one constructing the block. So transactions in the mempool tend to be added to blocks in a predictable way. Most recent wallets come with a fee estimator to position the transaction in a favoriable place. The accelerators is like a fast pass for future blocks found by the pool offering the service. |

What is secure to you? Security in this matter to me is knowing and controllng where my private key is and what has access to it. I wouldn't know where my private key is on a propritary mobile app, nor what I can do to control what can read it.
Edit: As an example, I chose to run my core wallet as the only application outside of firewall software on a desktop connected only to a private bitcoin node I control. It can't reach the outside world nor can the outside world reach it otherwise. I distrust this setup less than having my keys on a mobile device, though I use mobile too on occassion for convinience knowing the risks.

As long as you know you are only downloading trusted and safe apps, why would you be in such a high danger of malware on a mobile compared to a regular computer?
PC gives the user more ability to be secure than mobile. If you need to remove malware from your PC often, don't use a PC wallet. Functional distrust will protect you more often than trust for this particular question. |

Let me do a newbie question, please sorry if it's a too dumb question.
Would it be possible to change the firmware ( or something else ) of the 2Pac GekkoScience to mine with a different algorithm? Like Scrypt?
For firmware, not likely, the 2pac is an ASIC. Meaning its designed specifically for a single algorithm and this is hard coded into the hardware during manufacturing. They could release another version of the 2pac with different a algorithm but the one you already have will remain as is. No. That is not how firmware works and there is nothing else you can change on the 2PAC to change its algorithm.
Yes and yes. These Bitcoin ASICs are application specific to Bitcoins. Long answer:Logically bitcoin hashing involves a double SHA256: SHA(SHA(x)). But most application specific one does a: SHA(m [+ s] + MODIFIEDSHA(w + n)) and checks for leading zero then returns n. m=pool created midstate, s=driver created partial sha (chip specific), w=driver created leaftover from x, n=chip created nonce Which results in logically a SHA(SHA(x)) at the pool. Short answer:They are hard wired and not programmable in any way. |

I'm having some issues with a 2Pac, wondering if anyone has any ideas...
Was working fine; PC rebooted unexpectedly, and now I cannot get cgminer to recognize it. (have tried multiple PCs, fresh installs, etc.)
-Green light stays illuminated
-Windows recognizes device - shows in devices and printers
-when i run cgminer.exe -n, it finds device, and lists as GekkoScience 2PAC Bitcoin Miner
-when cgminer.exe is run either via batch or just launching the executable - always states 'No devices found' (cgminer build is confirmed working with other 2Pacs)
-have verified and re-installed winUSB driver via zadig 2.3
-checked with mutimeter - pulling 0.02a, 5v, 0.217w
any ideas or assistance would be greatly appreciated.
Thanks,
CJ
Hi, just to clarify! You have 3 Sticks, 2 are working in the same Computer and with the same Cgminer (VH's) version, but 1 stick is not working? is that so? There were 2 devices running on this machine at one point, one of those devices is no longer being used. The single stick that I have currently was running on this PC without issue prior. Thanks, CJ For some reason sounds like the chip is not getting enough power to run anymore. Move around the PC and try a port on a different controller or use a powered hub (recommended). |

For that, head over to the Marketplace (read-only) / Trading Discussion section. There are posts pin at the top of those sections/sub-sections with good informations and tips regarding scams and scammers. As well as documented scam activity and interaction logs of how it played out.

Sounds like quite a step into the cryptocurrencies arena. Since you have some miners on hand, head on over to the mining section https://bitcointalk.org/index.php?board=14.0And start interacting with the pool owners and community. Keep in mind it's a bitcoin section, take extra time making decisions, and be mindful of scammers. |
