Reading the first page people are not falling for it too easily. IPO + premine without a spec of innovation = hard sell and who knows if it will even make it to an exchange.

Stupid question about Scryptguild... I'm not always the brightest and I'm trying to figure out how to set up the coin reserves so that for Dogecoin and Litecoin I save half of everything I mine and convert the other half to BTC. How would I go about doing that?

I'll have to try 850/1000 clocks later, but at 947/1250 (avg 820 kH) or 977/1250 (avg 860 kH) my 290s seem to do okay. Here's what I've had a chance to test for a couple hours now:



One of my "test" mining rigs:


Edit: I should note that GPU-Z reports Watt values between 165W for the lowest card and 198W for the highest card now. If 850/1000 clocks can cut that further and still maintain an average of 800 kH per card I'd be very happy.

K nice, great info. For 850c/1000m, that is a 290x getting 800kh/s. For 290 you may want to try 900c/1000m or possibly 925c/1000m. But i'm not sure if I'm running that mem/core ratio wrong. I think you can probably fill out 800kh/s pretty well with a 290 at 1000m though.

Need a watt reading from the wall to using a kill a watt or similar meter. This has made all the difference for setting me on the underclock/undervolt vs hash ratio pitfalls and benefits.

Looking at how my 7950 gets 650KH/s, the R9 290 getting only 800KH/s seems so little considering how power hungry it is.

FYI, the Kimoto Gravity Well block difficulty setting algorithm (EDIT: Sorry, Dogecoin is implementing DigiShield, which is similar to KGW but supposedly improved, hopefully it won't have this problem) was found to have a flaw. Coins with fast target block times were more easily affected by it. E.g. 30 seconds. But it's not inconceivable that it could show up in Doge with its 60 second block target.

https://bitcointalk.org/index.php?topic=421615.msg5670580#msg5670580

Darkcoin (among others) was affected by it, and the Darkcoin devs have released a new version they are calling Dark Gravity Wave.

Oh and somebody is going to attempt to break Auroracoin based on it. So, you know, fair warning and all that:

You can undervolt the 290s and still get 800 KH/s though. I'm pretty sure the 290 ends up being more efficient.

I have my 290X doing 840 KH/s on 0.984v, haven't measured power usage though.

Not sure what's happening but of 3 290s in this one system, the top card is suddenly running at ~640kh/s whereas the other cards are running at 777kh/s. Card clocks are at 900/1000 and at 18 intensity running scrypt. It was running perfectly fine before. Things seem to have changed when I changed the "extend overclocking limits" setting in Afterburner. Clocks, GPU usage, etc look to be fine according to AB monitoring. Tried reinstalling AB but that didn't fix the problem.

Anyone know what could be happening?

Is AMD's CCC running in the background, denying Afterburner from actually changing the voltages/frequencies? Either way, shut that sucker down if it is (end task from task manager).

I started with Blackcoin for a short time on release. I didn't even notice the change to POS until after the fact. I left my coins in the pool since I thought I'll transfer them to an exchange if they even make it to an exchange. I thought I'll start avoiding installing all of these new coins wallets if possible since there have been attempts to put malware in them etc.

I was traveling for a while and when I tried to get back into the pool again they had a notification.

Blackcoin can no longer be mined by PoW. It is only PoS now. You should mine another coin on our site like Zeit, Mint, etc. Please see the Blackcoin thread for more information
The one week you had to withdraw your coins is up. Wallet is now offline. We are not a bank.
DEDICATEDPOOL => I will avoid them
You may want to avoid them. Apparently they grabbed everyone's coins and sold them, at least those who didn't cash out within a week. I didn't see any notifications when mining, they apparently decided to make a few $ this way.

I didn't lose much at all, I just noticed when Blackcoin was skyrocketing and tried to get the coins.

Normally I would make a local wallet and immediately send them there. This is the only time I didn't and initially I thought it wasn't going anywhere (plus I didn't know mining was so short). This happened to be one of the few coins which actually went somewhere.

I just want to name them here, primarily due to my unawareness of the whole plan. I don't recall if I switched to another new coin that same day or why I quit BC but either way I had no idea that dedicated pool was going anywhere.

I will admit that I should have read more about the mining -> turning into PoW, since I missed that initially. In the end I don't care too much, but the principle is annoying to me since I didn't notice any info about going offline soon. The whole mining to offline may have been over a couple-few weeks, however I was traveling etc. and not following it and it was very quick when you don't expect it. I'm just glad I didn't sit on it any longer.

I emailed them and they just replied with an arrogant email about not being a bank. Well, I will avoid them and name and shame them.

Get on BCMULTIPOOL.COM !!

For everyone else : It's the first "PoS only" coin to offer a mining service for the PoS coin itself by mining other alts, exchanging into BTC -> BC then paying the miners in BC! Beta was released today, but this is something brand new that no coin has tried. If you own BC, you support BC just by mining at this pool. It just took a giant step above any other PoS only coin imo.

Just in time too, it was released today and full release is early next week. Pool operator is reporting to see 3.5x hash rate on the backend putting it at over 1 GH/s. The price of BC has risen almost back to PoW week levels now because of this. It's about 300% from recent 500 satoshi lows, and $1 million cap (still low compared to the closest other coin - MINT at $2.3m)

Pool owner, Binaryclock, had the pool open 10 days after POS started.

Keep better track of your coins :awe:

I've never had a problem with Dedicatedpool

That's an asinine comment if I ever saw one. But given you hardly ever have any real knowledge about topics of discussion you inject yourself into, let me clear things up a little.

Given I know what's involved in running a pool, leaving the pool up for an extended period of time - a month, 3 months, even a year - would have negligible impact on the rest of their pools.

What's more, given that's BlackCoin changed to Proof of STAKE, that's a pool operators wet dream right there, to have idiots (no offense wand3r3r) leave their coins in the pool wallet. That's free money for the pool since the stake would be credited to the pool's wallet as liquid funds and not the individual miners at all. Dedicatedpool actually LOST money by doing what they did.

Not only that, this isn't the first time Dedicatedpool has done crap like this. They give little notice to shutting down pools, and they do it in such a way that they maximize how many people get scammed out of mined coins. It's their MO. Saying "we're not a bank" is a cop-out, they're just trying to make themselves sleep better at night.

I have only thought about this for a short time, but I don't think this is actually that serious.

The reason is that when the block chain reorganises following this kind of attack, the chain with the lowest difficulty sum will be orphaned, and the chain with the higher difficulty sum will be preserved.

The blockchain prevents mining blocks "in advance" by virtue of its Merkle structure, so the attacker would have to have a substantial proportion of the hash rate to stand a decent chance of success, as this type of exploit essentially requires a 51% type attack.

Of course, I'll be delighted to be corrected, if I've misunderstood it.

I still think he should have had set an autopayout. If he didn't reach the payout limit, he shouldn't have kept his coins at the pool. It's always vulnerable to loss.

What is going on with KDC? I've updated my wallet a few days ago but I cannot get it to sync even though I have plenty of active connections.

No I don't have CCC installed on that comp, just the driver.

I did a clean install of Windows and redid everything as it was, just with the card in a different slot and it is exhibiting the same symptoms of slower hash speed than the other cards (it was running at the same speed before). Card is hashing around ~640kh/s whereas the other 290s are hashing at ~777kh/s at 900/1000.

Looks like something DID happen to the card. Could a cluster of shaders or maybe a memory chip have been damaged somehow? But leave the card functioning?

guys I've had my 2MH miner pointed at clevermining for the past 3 weeks and haven't really kept up with the scene lately. Can someone tell me if I am missing anything by just multipool mining and not staying up to date on all the new coins?

I'm the first to admit and acknowledge that I should have setup auto-payment. I've never done this before, but this was a perfect setup for failure due to multiple reasons.

1. I chose that pool due to seeing it often for many coins.
2. I didn't want yet another scamcoin wallet running on my machine
3. I missed the change to PoS
4. I was AFK for many days
5. Most importantly I didn't care about the coins

Basically I would just say I'm trying to spread the word since there is no shortage of scams and issues out there so this is another thing to watch for. On one hand I hardly blame them, but on the other hand it was a bad move from their part regardless.

On a side note, the BlackCoin devs are figuring out the perfect pump scheme! It's wild and I wonder how long it will last.

Hey I just wanted to say I totally agree with you and I feel that what happened seems immoral, and is most likely illegal depending where their are located. Do you know if they are in the US, and what state laws might apply? You may be able to file a lawsuit in small claims court at your local city/state, and get a judgment against them. I just can't get over how they are thinking it's justified to just keep someone else's money? That's so weird? I keep coming back to the idea that if nobody punishes them, they will do anything they can get away with. The world is filled with people like this, and I like to make a point to let people like that know that I'm happy to bring a [doo-doo]storm their way, because hey, you had big enough balls to think you could get away with it, well, let's see how that works out for you... But it's really going to come down to whether it's worth your time to battle it out. Maybe if you approach it like a hobby and learning process about the legal routes to paying back some justice to those d-bags who feel they are above the law and out of the reach of justice. Otherwise it's probably not worth your time. However, another route might be to contact the district attorney wherever these guys are and explain in very simple terms how they are making off with everyone's money. That might just be the spark that sets everything in motion where the attorney is simply looking for someone to come forward to claim a loss, and and give prosecutors the impetus to make a case to shut down these guys or go after them, sort of how the prosecutors went after "money changers" who were taking big cash from people in exchange for bitcoins etc.

But to clarify, I'm assuming the pool operators are doing a bad thing, and the thing they pulled is actually in the wrong. I wouldn't feel this way if it were just incompetence or accidental etc. But everything i've heard, they are just use the same dirty tactic that they've developed over time with practice and feel immune to any justice because nobody went after them so they'll just keep doing it over and over again.

BlackCoin passed DOGE today for #3 in trading volume. It has been an absolutely hectic day for BC over a Mintpal. There were some 50% price swings that happened in span of minutes.

BlackCoin is a trader's dream right now, but I doubt it will have any staying power. It simply doesn't have a business plan and any relevance in the crowded crypto market.

What's more, the name is a major turnoff.

Thanks for the tip about the pool dumping BTC into BC though. I bought a bunch cheap and dumped it today near the peak for ridiculous profits. Only coins I'm holding right now are BTC/LTC/DOGE.
