Warning possible keylogger or sensitive data extraction please reinstall your OS if you have already lost some bitcoins
I've dealt with hdclover on the 9.5.13 selling him YACs. He was desperate to get more.

Anyhow I have checked the BTC address he sent my payment from and there is nothing missing. So either hdclover had a different wallet.dat corrupted or did not lose anything.

Anything else, make your own conclusions. And feel free to repost that to the other posts he did.

Which can be difficult at times because they ask for proof of residency and don't accept black and white when that's the only proof I have access to.

okpay is rubbish at that. My proof of address had a small color logo on the top right and was black and white otherwise. okpay would reject it automatically... their color-detection algo is broken imho.

However, I loaded the pic in IrfanView, added a bit of color tint (red or blue? can't remember) in the color settings. It went through their automatic check and was soon after accepted.

In case you haven't realized yet, this is a zero sum game. Anything you make, someone else loses. No matter if I'm part of a group that's pumping and dumping, or just a lucky loner, anything I gain is a loss for others. Morality is irrelevant.

What? In the real world we call stuff like this "insider trading" and people get sent to jail over it.

The laws don't apply here, but the principles do.

First, you just said it, the laws don't apply here. Second, it's only insider trading if you are a part of a company behind a stock. Since no one owns cryptocurrencies, and they don't generate revenue, insider trading is impossible.

So many "finance experts" here with their knowledge of market rules based on watching Wall Street the movie. You can go to jail for trading even if you do not have inside information on a stock.

Market abuse covers insider trading and market manipulation. Wikipedia has a good definition of the latter: http://en.wikipedia.org/wiki/Market_manipulation
Quote
Market manipulation is a deliberate attempt to interfere with the free and fair operation of the market and create artificial, false or misleading appearances with respect to the price of, or market for, a security, commodity or currency.
For example:
Quote
Runs: "When a group of traders create activity or rumors in order to drive the price of a security up."
Pools: "Agreements, often written, among a group of traders to delegate authority to a single manager to trade in a specific stock for a specific period of time and then to share in the resulting profits or losses."

So yes, you could eventually go to jail for your proposed actions on a regulated market. I am not a legal expert and don't know if it applies on BTC-e or MtGox, and quite frankly I do not care as I would simply never get involved in such a scheme.

It also makes a lot of sense that the CFTC is planning to regulate the Bitcoins exchanges. If anything it would be good for Bitcoins if it was regulated - at least if you engage in a legal activity and you are not in it for money laundering or fraudulent activities.

I like Geschwindigkeitsbegrenzungencoin but "coin" should be "zahlungsmittel". Geschwindigkeitsbegrenzungenzahlungsmittel sounds much better. Maybe instead of "ver. 1.1.1.1" you can use something like "I/1 Ausf. A1"  Smiley.

"Geschwindigkeitsbegrenzungenzahlungsmittel I/1 Ausf. A1" looks really awesome.

Sounds like a coin to pay for speed tickets then? Wink
What if it is only valid on the Autobahn? Autobahngeschwindigkeitsbegrenzungenzahlungsmittel?
And the first pool could be named Autobahngeschwindigkeitsbegrenzungenzahlungsmittelabbauverein.

Please, please pick a shorter name!

149  Alternate cryptocurrencies / Altcoin Discussion / Re: The YACoin Superfun Premine Thread on: May 10, 2013, 05:21:24 PM
I would imagine you started mining sooner than 8 hours after the launch of the coin, and didn't make your estimate based on your block generation rate right when difficulty reached 0.1.  Otherwise, if you were 1/1000th of the network hash power, you would've been successfully mining between 2 and 2.5 non-orphaned blocks per hour on your 6-core i7 at that point in time.  Or if you were 1/600th of the network hash power, you would've been successfully mining between 3 and 4 non-orphaned blocks per hour.  Is that your claim?
Correct - I have mined 3-4 blocks in less than 2h. There was a new block every 2-4secs if I remember correctly, so 900-1800 new blocks per hour. I switched off yacoin-qt sometimes in between, so there are gaps.


You'd have no way of knowing I didn't just lift someone else's data center photo off Google Images anyway, unless I went around scribbling silly YAC-specific messages on everything with a Sharpie to prove otherwise.
Photoshop? Wink

I didn't doubt you may have one rack with a few blades. I know that old blades are cheap on ebay, but are pretty power-inefficient, so usually sold off by large companies. Heck, even one of my colleagues had a rack server at home when I was doing my PhD.

Not including the additional blades used as file servers for all the other blades to network boot from, we're talking about 197kW.  It's >200kW if we count cooling however (62kW more, for 60 tons of HVAC).
Uh, I feel so bad, 3kW short! And that is for someone who is more into statistics than into building blade farms and didn't bother to google it. Cheesy
The error in power costs is easy to explain: UK is more expensive.

If you're actually curious, my cluster is rented out for large 3D render jobs for film projects.
Yes, that's interesting. It'd be a nice project to have people rent out their CPU cycles for a distributed renderer instead of mining coins... The upload bandwidth would be a bit shitty and introduce some render latency, but probably negligible.

If you've had any experience with the BladeCenter platform, you may be aware that this hardware doesn't fail particularly often (I can count hardware failures in the last year on one hand) and managing an 800 server cluster is a 1 person job.
Hmm, our infra team is a bit larger and we do have quite a few outages throughout the year. But then, we are actually running disks in them that fail, discover Redhat-Linux bugs along the way and monitor network latency very tightly.

Pocopoco added a checkpoint via a GitHub pull despite not saying anything at all over here, and at block 15,000 no less.  Why?

To mitigate 51% attack, no?

Possibly, it's hard to tell.  He might also be locking in blocks that are his own if he mined a bulk of them in the first 15k blocks.

This is getting more and more bizzarre. Do you argument the same way for checkpoints on the BTC and LTC networks? You don't like a checkpoint because of what? Because it prevents people to attack the network and steal coin? I would think this a very positive thing.

This is a young coin, so the fear of a 51% attack is real. Why would it be good if someone could do that?

BTW, pocopoco did announce the checkpoint in his original thread here https://bitcointalk.org/index.php?topic=196196.msg2083242#msg2083242. I rest my case. Stop being bitter if you feel that you've missed out.

If anything you can complain that the starting diff was too low (and that you were not online then, see my posts on "fairness"). There are ~2.34 Mio coins out by now. That still is much less than FTC (6.5 Mio) and CNC (5 Mio).
151  Alternate cryptocurrencies / Altcoin Discussion / Re: The YACoin Superfun Premine Thread on: May 10, 2013, 07:17:23 AM
I don't think the Dev has a GPU miner nor do I think he has a server farm, if he did no one else would've won any blocks when the binaries were posted. However if 6000 cores only constitutes 15% of the hash then something is fishy, the alts forum doesn't have 20,000 people reading it. Regardless the coin was doomed from the start, six second block times are fine if you're the Visa network paying for your storage, but at 35mb a day you can't very well tell gramma to send you money but "oh, it'll take you a week to download the block chain".

I already turned mine off. 500 watts an hour isn't worth it for 16 cents worth of coin.

Minor nitpick, but since it appears to be based on my report of the hash rate contribution from my 1560 server mining farm experience, it was quite a few more cores than 6000.  800 of the servers were IBM HS21 blade servers containing two Xeon E5450 processors which each have 4 cores, so each server had 8 cores, so 6400 cores for the main server farm.  A Xeon E5450 is pretty similar to a Core2 Quad but with significantly more cache memory tacked on.  The Amazon c1.xlarge instances have 8 cores worth of Xeon E5-2650's, though are shared servers.  Generally the 760 c1.xlarge instances performed at about 2/3 the hash rate of the dual E5450 servers, so we can probably call those equivalent to 2/3 of a dual E5450 server.

So, more accurate estimate would be that around 10450 cores (equivalent to Xeon E5450 cores) constituted about 15% of the hash rate at the time that I stopped mining when difficulty reached 0.1.

You are funny. But it gets on my nerve when people are not telling the truth.

1) I mined very successfully with a hexacore Intel i7 up until difficulty 0.1-0.2. From the number of blocks generated I estimated that I was 1/1000 - 1/600 of the network. Check my posts, I posted that when it happened, not when I felt bitter about not getting enough coins or in need to disprove you. Maybe your setup was wrong.

2) You show a pic of 1 blade rack on a table (!) and want us believe you have access to a whole blade center consuming >200kW power and hence costing 1000$ in power alone to operate per day? How much you'd have to sell your YACs for to be profitable?

3) Did you lose your job already? Seriously if you did what you claim you did, you should be worried! Blade centers like this are operated by companies with >>1.000-10.000 employees. I could have tried to use my employers compute blades (20x2x8 xeon cores). Your Infrastructure team must be morons if they have not seen the traffic/CPU etc and acted upon it.

4) you install possibly harmful software on company resources?!? And possibly disrupt company operations? For a few coins? WELL DONE DUDE!
152  Alternate cryptocurrencies / Altcoin Discussion / Re: The YACoin Superfun Premine Thread on: May 10, 2013, 12:01:14 AM
Yet the Windows build gave me 60 KH/s while my Ubuntu build gave me 400 KH/s with my 2700K -- totally different story.

Anyway, who wants to buy some YAC?

400 KH/s?
I'm getting merely 200-400kH/s on my Intel hexacore. That said I cannot use the AVX optimisation as it runs inside Virtualbox. However, I don't see how this is a totally different story -- we have the same with ASICs for Bitcoin, GPUs that arrived for Litecoin etc.

YAC might not be more "pure" than other coins. But at least it is a new concept and not a simple clone such as FTC and CNC. I have my doubts whether it is the right concept. But only time will tell.

I also find it hypocritical to ask for a "fair" coin. What is fair? Fair, so that everybody can profit? Fair, so that "I" can profit enough and in particular more than the other guy that I'm envious of? Fair, so I can dump it onto buyers and cash out?

Is anybody even remotely thinking about the original motivation of a coin? To make digital payments easy and secure. Mining surely was more of a necessary evil (consuming Megawatts and 100k$/day) than a wanted aspect of the network. I could think of a strategy that should limit the required mining power.

Unfair is when I make lots more than everyone else for no greater effort -- which is what I've done repeatedly.  Like I said, I got a bunch of YACs.  But I figure people not into the crypto p'n'd' scene will fail to see the value of something that has ponzi-scheme like distributions in the first week that it's out.

Your definition of fairness is socialism: making as much as everybody else, adjusted for effort. Oh, and of course making as much as everyone else at the cost of someone buying all these coins. Hmm, not quite socialism then. Wink

I'll give it another twist: it is unfair by your definition that you have mined LTC a long time ago where difficulty was low, stashed it away and then sold it for a much higher value than anybody else who sold it after mining it? FRC with demurrage would be more fair by that definition. However, I believe what most people mean by "fair" is that it should make everybody equally rich, quickly and easily.

And here is a last twist: you speak of people seeing or not seeing the value of a crypto. Again, what is the value of a crypto? I'll offer some ideas:
- entertainment (hobby and way to spend time)
- educational (learning about computers, crypto and programs)
- whatever the other guy is willing to pay $$$ (covers speculation and investment)
- a tax efficient way for gambling (BTC trading is the cheapest "lottery" I know of)
- payment processing (yawn, boring)

I'm just trying to do a transaction with hdclover. I suspect he might be a scammer - BEWARE!

I've been waiting >1h for a confirm of his BTC payment, but it didn't go through yet.
Is this normal?

The transaction details are here:
https://bitcointalk.org/index.php?topic=193109.new#new

edit: I got 1 confirmation now finally.

I assume trade was successful and added it as so. If it didn't please let know!

Yes the trade was successful (2 confirms and counting).

Please remove me from the seller list.

Is solomining this still profitable ?

Hard to tell until we see at what exchange price it stabilizes. A block now is 30 YACs, if it was priced like NVC and you got one block a day, that would be 1 BTC a day.

There must be a herd/block of YACs running through the network right now! And there were flocking into my wallet!
I didn't get anything for 6h and within the last 1h I got several blocks. Maybe it's because I've been reading the thread and thinking about YACs a lot?  Wink   To be honest, I'm quite puzzled by this inconsistency. Might be about network latency or whatever, I don't know.

Wow, the difficulty is really going up now and double every 8h.
It went from 0.073 7h ago (3:25am) to 0.16 now.

We really need a mining pool soon!
159  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][YAC] yacoin: yet another altcoin. START is now. on: May 09, 2013, 07:25:10 AM
"difficulty" : 0.07315276


Hash rate:  68kH/s   Difficulty:    0.07315276
Expected Time   1 hours 17 minutes
Probability of a Block in 1 hour   54.12%
Probability of a Block in 6 hours   99.07%
Probability of a Block in 12 hours   99.99%
Probability of a Block in 24 hours   100.00%
Probability of a Block in 7 days   100.00%
Probability of a Block in 14 days   100.00%

These numbers probably don't include orphans/stales. I'm running on an i7 3930k with a hashrate between 200-400kH/s.
I am getting roughly 1 block every 45-60mins confirmed.

The block reward is dropping pretty fast still and is now ~36YAC. As far as I understand the reward decreases with increasing difficulty and increases with increasing N.

Does anybody have an idea when the N increases?
