Someone on the french forum about mining i come from run some tests with a simple rig setup, with 2 x R9 280X All tests ran with the same frequency etc.. Each algo can be optimized, but for comparison, it's good. Power at the wall: Idle
80-90w
scrypt
550W - 2 x 720khs
Scrypt-N
537W - 2 x 350khs
Scrypt-jane
485W- 2 x 133khs
Groestl
271W - 2 x 7 025khs
Myr-G
295W - 2 x 9 920khs
skein
440 W - 2 x 212 500khs
Keccak
430W - 2 x 316 000khs
X11
285W - 2 x 2 080khs Result : Groestl is the most gpu friendly algo, for power, temp and noise, even better than X11  a little tuning on one of mine: 4 R9 280x + 1 x 7950. 3 R9 are overclocked at 1250MHz, the 4th at 1150MHz - 1.2v The 7950 runs at 1100MHz - 1.15v Memory for all 4 run at 1000MHz Look at the temp (scrypt : between 75 to 83°C) sgminer 4.1.0 - Started: [2014-04-04 20:27:39]

You can ignore me but you cant ignore the truth.
Dev probably dumped his instamied coins and moved on since this project didnt get as much attention as he wanted.
In the meanwhile the price has fallen by more than 30% this week.
I didn't know you were the voice of truth ! sorry ! Like when you were suporting skeincoin ! What, skeincoin, what is it ? Yeah, another coin that died...So, you can be wrong ?? Seriously, if you know the future, you are already rich and you have other thing to do than educate us... Man, we didn't care if you are right or not. We believe in this coin, you don't. Ok, no problem for me, if you don't believe in this coin, it's your right. But why are you here ? I can't undertand. You complain about instamined. It was not. Premine ? all premine was guiven in bounty. The fact you think you come too late ? It's not too late. |

we need so much votes to go on mintpal.. This voting system were you have to pay to vote, don't like it.
We need Poloniex, but there is no hurry.
Actually, with the low BTC rate, many people dump their altcoin to get BTC and then to get fiat...
When the trust in BTC will come back, we will see more interest in altcoins, and in GroestlCoin. It will be the moment to be on a big exchange.

X11 is an example. There is some other good (better) algos to use. Groestl got my preference, but there is also blake, fugue, qubit, and not as good but still better : skein, keccak, ink, etc....

Will Cudaminer work for this?
Yes, cudaminer should work fine for scrypt-jane. I've got nvidia gpu, I will test latest cudaminer before the release. X11 is better than scrypt-jane, please think about it.
are X11 memory intensive somehow, or does it have other properties making it expensive to build ASICs for it? I read the opinion that it is easier to make an asic for x11. Also x11 is cpu minable, with current situation on cpu coin scene (with extremely low profits) huge botnet can easily jump on the coin. Lower mining temps just indicate that the gpu doesn't work at full power. I doubt that there will be an asic for scrypt-n or scrypt-jane in near future, because these hash algo have got an option to change N factor easily. The time X11 asic come to reallity, memory will be so cheaper than now, you will see scrypt-n / or scypt-jane asic too.. It's not an algo matter, but a success matter. If a coin is very succefful and popular, Asic manufacturer will make a product for it. But we talk about millions or billions market cap. Scrypt-N and scrypt-jane are also gpu resistant.. configuring a mining rig for scrypt-n or scrypt-jane is not always easy. It's not very popular. X11 is. You have also others algo you can use (Groestl for example) Changing N factor to protect the coin is theorically working, but it make miners to have a lot of Ram too. With scrypt-N with 3 GPU (r9 280x) on EXE or VTC coin for example, you need 4Go of ram (to have full hash power). With 4 or more GPU, you'll need 8Go. If the N factor is higher, you will need 32Go on each rig ? There is 2 way to be really asic resistant : the ability to change the algo with a fork if an asic is coming, and multi-algo (like Myriadcoin). Myriadcoin is not asic resistant, it use sha256d and scrypt, but also other algos. So, miners with asic can mine it with their own difficulty, and "little miners" like us can too, on actually asic resistant algo, with their own diff (lower). So, i think the only thing that matter is not asic resistant or not, but coin being popular or not. If you want to succeed, you need your coin to be at least popular. Scrypt-jane and scrypt-n are not and will be less popular with summer coming. Choose your algo wisely, with this in mind. |

Ok, lets be clear here. Nobody in their right mind is buying this crap. Everyone is mining with a hope of dumping their coins once the price is high enough to get btc/fiat. Nobody will mine it after some time because the block reward will just get too small and the network will slowly die. This coin will be dead within a couple of months.
frustrated ? I'm sure many people says the same thing about..many coins. Some succeed, many not. Nobody force you to mine or buy Groestlcoin, (or to be on this topic neither) Its my right to show people my view on what this coin really is. A few early miners might benefit from this in the short term but in the long term the community will suffer. People will see that they invested in a scam and will avoid risking their money with cryptocurrencies again. It's your right to have a different opinion. Wanting everybody to adopt yours is trolling. There is a lot of altcoin threads you can troll on, please choose (another) one. |

Can anyone explain to me why would anyone invest in a coin which heavily favors early adopters? I mean whats stopping people from dumping 20% of all the coins mined after 1 month?
Klondikecoin did something similar. It had 77 coins per block in the beginning, then a lot less (16 afair). Its price has fallen more than 20x.
To anyone reading this: please think and do some research before you buy this coin.
It's not too late to be an early adopter. This coin is 10 days old, you have not missed the boat yet. Reward was lower than at start, (480 instead of 512) but only by 6%, not half. Diff is not too high for the moment, and price is low. I mine it, but i buy it too. What's stopping people from dumping ? Nothing, just look at the bitcoin, chineese people (and others) are just dumping it right now. Are they early adopter? Not sure. But after 10 days, some GRS were dumped, and we bought those. Coin value is pretty stable for a new currency ( in comparaison to others) Summer is coming. with heat. Scrypt asics in volume too. Alternative algo like Groestl, which consume 1/2 less than scrypt and 1/3 less heat will surely retain attention. |

I like to give a try, you can keet your btc, i'm just curious.
Any chance to adapt it to riecoin?

Voted for GRS.
So cool to mine, so much potential. My GPUs are much more cooler than keccak, even overclocked (not to mention scrypt and co, half the power consumption)

Groestl is good coin for mining, it's very cool, low energy, quiet... but why people dumping the GRS price?
Dev, can u do something interesthing for pump pump pump the price?
People are dumping their coins because its just another pump and dump coin with unfair distribution. Better do the same while it still has some value. yeah, do that. I will buy more |

Price lower 5 satoshi. Someone (include DEVs) use ASIC SHA2 modify to SHA3. Them's hashrate very high. Top 1 on Okaypool at 6.4 THs ~ 18000-25000 GPUs 280x
If one pc have 4 GPUs 280x >> 4500~ 6500 Pcs. Just ASIC SHA2 modifyed to SHA3!
This coin will die soon. So DEV want exchange hurry up
No sha3 asic, but surely stratum hack/exploit. It's worst, as they don't even find any block, and it doesn't cost them anything to earn all the bloc reward I returned to GROESTLCOIN mining |

Hi Everybody! I'm a senior software architect at a large company (not related to crypto or www) and crypto currencies is my hobby since December 2013 (I've been through LTC, Doge, multipool and Myriad mining). I'd like to share my thoughts regarding Groestlcoin purely as a miner and investor... First, respect to developers for creating this coin. I really like the total amount of coins, the 6% reward decrease, it's CPU friendliness and much less heat/noise from my 4x r9 290 while mining GRS. But there are some things which I think could be improved. There are some many different coins nowadays and it is hard for a good coin to stand above the rest. Coin value is only decided by the price other people are willing to pay for it. If nobody knows about a coin, then its value can't be large. My biggest concern is that GRS lacks publicity. Just google for groestlcoin and you'll only find a few links. There is no Twitter and no developer communication... Please also see my recommendations (in no particular order) * It is not stressed anywhere that mining this coin on GPU consumes a lot less electricity and makes GPUs quieter and cooler. And that it is still CPU mining friendly (CPU is only a few tens of times slower than GPU). No recommended cgminer settings for hardware, etc. * The fast coin reward decrease should be also stressed to attract more mining and investors (mine/buy while there are many coins). This will get the GRS market going. * Website design is amature. Compare with http://www.darkcoin.io/ for example. * Who are developers? What are their plans? What is their contact address? What is the planned coin future? * Coin explorers don't report the coin amount properly. For example, it is off by about 30% for my account. Presumably, it is because they don't account for mined coins. * We need articles about GRS. Raise awareness about the coin. * Set up twitter and paste it in main groestlcoin.com page * Possibly set up trello.com account and post improvement ideas there, assign work, track progress, vote on features. Fundraise for some features. I'd be willing to help with what I can (can set up and organize trello and/or set up mining hardware settings list, for example). I'd like to join the dev team and help with what I can (if this is an option, of course) Also, I'm planning to set up another GRS mining pool on a fast server, I'll keep you posted about the progress. PS: Please share your ideas and vote for the coin on exchanges. Thank you +1000 Key feature are at least : -different algo, multi-pool resistant and (actual) asic resistant -energie efficient, even more than X11 : gpu run quieter and cooler, and consume much less energie than scrypt or even keccak. -Old gpu friendly : a HD 5870 perform like a R9 280x -CPU Friendly : gap between cpu perfs and gpu perf is much lower than with other algos I don't know how i can help on my side, but maybe by making french translation, mining guide etc |

This coin looks promising  It is fair for CPU & GPU = GREAT POTENTIAL Haha,really? Once GPU's come in,it's all but over for the CPU miners. Coin's good,I agree,but saying it's still good for CPU is just wrong. It's still possible to mine with CPU, difference is not as huge as scrypt between CPU and GPU. For example : 3930K @ 4.8GHz : 2.4MHz 2 x Xeon 2687W : 4.5MHs Ok, it's far from GPU, but with scrypt, ratio is x 100 |
