 Black Whale Community Pump (4/25/2013 - 8 PM EST - NYC Time)
The BlackCoin community are once again about to make history!!! Never in the history of crypto has a community rallied together to pump the price of a currency in an attempt to break the control of unscrupulous whales!!! A global pump with hundreds of people working in unison will be nothing less than epic!!! We will become the "Black Whale".
On Friday 4/25/2013 - 8 PM EST - NYC Time we will begin buying massive quantities of BlackCoin to stop the blatant manipulation of some holders who are purposely suppressing the growth of BlackCoin. This community will pump over 300 BTC into the BlackCoin ecosystem to consume the low priced sell walls.
We as a community will have to pledge to each other to follow some basic guidelines.
1.) You will only trade on Mintpal @ 4/25/2013 - 8 PM EST - NYC Time.
2.) You will buy at market price and not buy on dips.
3.) You will not use this opportunity to sell off the coins you already hold.
4.) You will not sell any of the coins you buy for 3 days after the community pump.
I would like to formally ask the multi-pool operators to hold off buying coins for the next two days and join us on this epic event!!!

The main pool is still down!  ?? I thought it was gonna be fixed. For those that have been asking, we plan on having the official pool back up and working later this evening or first thing in the AM.

+1 The higher the price of BC the more obscene the predictions get. People need to keep their cool, I know it is very easy to get swept into the hype when prices start to fluctuate, people start imagining yachts, sports cars and mansions. everyone who is thinking this is the next bitcoin and putting everything into it, especially the new people, this is very dangerous, and you will probably get burned.
whenever an investment is a sure thing or too good to be true, it usually isn't, since forever. being digital dont make no difference.
its worth holding a few BC I think based on big community and its performance to date...
but DONT sell the family silver, as unlike Bitcoin which didn't have the competition around now, BC's recent performance can change in a nanosecond with something else happening in the market, and all the fundamentalist BC bitcoin millionaire wannabes will turn into an army of fundamentalist bagholders trying to pump to 100 satoshi claiming BTC has a 'great community' if you catch my drift.
cheers
This is good advice. Never invest more than you are willing to lose. Cryptocurrencies are closer to gambling than they are to investments. However, if you do your research, it is more like gambling while counting cards. Still, it is very speculative. Proceed with optimism and caution. That being said, GO BLACKCOIN!!!! |

If there is x11 coin support on the multipool I would definitely join in and so would a lot of other people. @dev/pool owner.. would you mind consider Scrypt N in your multipool? this is beneficial to those GPU miner looking for less wattage mining. There are lots of profitable ScryptN right now or probably more profitable than the scrypt coins. I am not mining blackcoin since it uses only scrypt. i do mine other scryptN coins then buy blackcoins.. i wanted to support BC but i want also to save electricity. Hope you consider this idea..  TIA |

I had that same error with my 7950 rig, once i added more ram i could increase the intensity and everything was running fine. Thanks, Benhur. I used the following cgminer.conf for 7970 and got 230KHPS. I was using "gpu-threads" : "1", after changing to 2, the performance improved from 110KHPS. But no matter what I do next, it is capped at 240KHPS. I can not increase the intensity either as the HW error increase dramatically if I change it to 14 or 15. What is your Scrypt Sleep level? { "pools" : [ { "url" : " http://127.0.0.1:9332", "user" : "john", "pass" : "1" } ] , "intensity" : "13", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "2", "thread-concurrency" : "8192", "shaders" : "2048", "gpu-engine" : "1100", "gpu-fan" : "30-55", "gpu-memclock" : "1500", "gpu-memdiff" : "0", "gpu-powertune" : "0", "gpu-vddc" : "0.000", "temp-cutoff" : "100", "temp-overheat" : "100", "temp-target" : "65", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "1", "gpu-threads" : "2", "hotplug" : "5", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scantime" : "7", "scrypt" : true, "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/usr/local/bin" } I have 2 r9 280X and 1 7950

what kind of gpu do you have and what are your settings? I can mine fine with mine with no decrease in hash speed so it is definitely something on your end. When I use an external cgminer, I only got ~105KHPS. I thought Scrypt Sleep is already required. I was getting 570KHPS earlier on Friday. Ever since I re-sync on Gridcoin with a loss of 7K GRCs, I started getting 105KHPS. So I suspect this must be something related with Gridcoin client monitoring the GPU usage and reduce it accordingly due to BOINC credits. Other than that, I can not think of any other reasons. Scrypt sleep is not functional @ the moment. Try an external gui-miner and see what kind of speed you get. I am using the embedded cgminer downloaded along with the Gridcoin client. I used to get 570KHPS. Now it is 90KHPS. My daily credit is about ~1600 these days. Not that high. My Scrypt sleep level is at only 69% currently. Are you mining with with guiminer external to Gridcoin, or internal miner? BenHur and Traderman, thanks for the reply and help. Yes, I tried rebuilding the blockchain after blowing away the Roaming directory, reinstalling the client etc. but it did not help. I went all the way back to early march and found one wallet which can be recognized by the client without the "salvage failed" error. However, after syncing up, it did not retrieve all the coins I had from Friday. There is a difference of 7K coins lost. I suspect that I was in a hard fork somewhere and kept mining without realizing the fork. I just don't understand why the 7K coins were accepted by the network just fine. Yet when I sync again, it just disappeared. Now I started mining again but found out that my hash rate dropped to ~100KH. Many times the miner is disabled automatically. I suspect that this is caused by the Scrypt-Sleep algorithm but am not sure. My Leaderboard Posistion is ~100. 100KH is just too slow and I don't know how many days will it take to solve a block. Can you guys comment on the new Hash rate? Should I accept this hash rate or there is something I need to tweak to improve it. Try that, that should work! It seems Rob has updated the gridcoin.us back to 2.1.0.7. I downloaded it and was able to sync.
However, I kept getting "wallet.dat corrupt, salvage failed" errors.
I tried all my backup wallets and all with the same error.
Also tried "gridcoin_qt -salvagewallet -rescan -reindex" with no luck.
Anybody has better idea on how to recover the wallet.
I was running 2.1.0.4 earlier. Could that be a problem?
Does anybody have the 2.1.0.4 version so that I could try whether I can recover the wallet?
Your help will be greatly appreciated.
Have you tried to rebulit the bolck chain? You can delete the files in "C:\Users\your PC user name\AppData\Roaming\Gridcoin" ,only leave gridcoin.conf and wallet.dat.Then run the wallet software Run as Administrator,the wallet software will restat and update.WHen the update done,it will download the blocks chain. Hope it works.  |

Hey Grid, what is the ETA on cpumining? That might be caused by me being a noob, but I ran "c:\program files (x86)\gridcoin\grcrestarter.exe upgrade" and still had the same issue.
Thanks for your quick reply though.
The testnet folder is no longer on the mirror; so it should not be possible. Verified. Upgrade works again. |

Are these guys legit? Has anyone bought hardware from these guys before? LTC Difficulty is dropping nicely -10% And Doge's difficulty is staying stable even with the +35% price increase These miners might be a good option: http://www.alcheminer.com/"This shipping timeline precedes KNC's and Mining ASIC Technologies' and is provided at a better price than Alpha Technologies' Viper line of Scrypt ASIC miners. In addition, the company has a July Shipping Guarantee, which is backed up by more hashing power if shipped in August or September and a full refund offer if shipping is delayed past that point (October)." Actually, that might be the taiwanese company that Grey mentionned a few times. They've done a Q&A on Reddit: http://www.reddit.com/r/BitcoinStocks/comments/23dcn0/rbitcoinstocks_alcheminer_alc_question_answer/ and are selling shares on Havelock, for anyone interested. |

I wanna see who here buys one of these planes. Would be pretty cool! So If someone were to buy the cheapest plane @ 140k Euro ~ 2300000.00000000 BC? Is that company gonna hold the BC or convert to Euro, cause if they sell 2,300,000 BC that would pretty much kill the entire BC market instantly LOL. I am not sure I believe they will accept BC, I will believe it when I see it however! I'm happy to announce that Dutch aircraft dealer "Zelf Vliegen" now accepts Blackcoin as a payment option.
In short, this means you can now buy your own aircraft with Blackcoin. Black meets black.
Blackshape’s Prime is an aircraft whose sleekstyling, unbelievable performance and unparalleled safety offer pilots all the features and handling of a general aviation aircraft.
Prices range between 140,000 ~ 250,000 euro / Blackcoin exchange rate.
For more information about buying a Blackshape Prime please contact the dealer "Zelf Vliegen".

When there are large amount of money involved anything is possible, it would be great if the multipool can show as it is buying the BC from the exchange, that would aid in transparency and it would be a great show to watch and promote Blackcoin even further. I think this is needed badly to boost confidence in Blackcoin. this is totally stupid without any proof. The operators of the pool stand to gain more by just supporting the coin. Sounds like a conspiracy theory. Besides what agenda do you have starting this thread?
|
|
|
|
|
I have a question.
How do we know the multipool operators are not front running??
I think it would be great if the multipool is showing the buying BC transactions as they are being executed on the exchange and distributed to miners.

That thought did cross my mind about the pool operators front running. I think it would be great of the multipool is showing the transactions as they are being executed and distributed to miners. I wouldn't be surprised if Blackcoin multipool did some front running during that crazy rally. Imagine being the pool op, with 100s of BTC in buying power, knowing that you can pump the price to pluto.
Pool Op buys up some BC, pumps the price of BC to da moon, then dumps. Meanwhile the Multipool miners get the raw shaft.
This is even better than scam IPOs.

So far we have dropped by 40% from the peak, if this keeps going I think there may have been a very organized group behind the pump. Hash Rate: (Scrypt: 5905.46 MH/s | Sha256: 60.71 TH/s) I have a theory on the multipool and I hope I am wrong.
If there is an organized community behind the pump I am almost certain they would have rented mining equipment to boost the multipool for added psychological effect.
Keep your eyes on the multipool to see if there are any large fluctuation in hashing rate. I saw a couple or large jumps when the pump was going that made me
very suspicious.
Maybe my imagination is just running wild, but keep watching the multipool.
