Bears, this is the buying opportunity, right now. Smart investors buy when the market is fearful, not the other way around.

Put on your big boy pants, place your buy orders, grab your iron mallet and do some troll hunting.

Bitcoin is currently in a denial of service mode.

"aantonop: Tx malleability is now used in active broad-based attack against bitcoin network. Funds NOT at risk, but Denial-of-Service in progress"


Meanwhile many Bitstamp and btc-e withdrawals have gone AWOL.

Some panic is in order. Kindly SELL in orderly fashion, before we hit the cliff.

So does this affect transactions in any way? No, it does not. I'll be kindly buying.

they're not insolvent I wish everyone would stop going on about this. How could you actually fail that hard? They make more than half a percent on many of their transactions. They have a workable business model (when it works - it works!) If they genuinely don't have the cash I have no idea how they could have lost it.
I can think of at least five ways:

1. They were hacked and tons of their bitcoins were stolen.
2. The police seized a large chunk of their assets as part of crackdown on criminal use of bitcoins.
3. They wasted a fortune buying bitcoins at 10-20% above market.
4. They sold the clients' bitcoins at 100 USD to invest, price rose to 700 and they could not buy them back.
5. They reformatted the hard drive that had the only copy of their private keys.

And there are surely many more.  The immagination of incompetent managers is amazing.


Even if they were so foolish, life will go on without Gox. Just look at the price difference now.

So, when are you buying in? Cool

I really don't need electronics lessons. I have actually measured the power draw of a number of cards. You said the powered risers power the motherboard, that is false. Most powered risers, including the USB ones I sell, do not even have any power connection to the motherboard, they only even connect to the gpu. The data signals are passed along the USB cable.

Ahh I see. Your risers have their own powered slot. The ones I'm used to seeing simply have the 12v line soldered directly into one of the 12v pcie pins on the ribbon cable.
1186  Other / CPU/GPU Bitcoin mining hardware / Re: Quick question on powered risers on: February 11, 2014, 02:17:15 AM
You can also use EVGA's power boost. It does the same thing as powered risers: stabilizes the PCI-E bus by providing it more current. Powered risers power the motherboard, not the card.

A full sized card, even on a 1x slot, is going to want to draw 75w. Yes, they are "rated" for 25w but can use as much as 75. All the power pins are near the front of the card so there's nothing stopping it from doing so--the card doesn't care if it's in a 1x or 16x slot. This puts more stress on the motherboard, which may or may not stand up to the load. Use a power boost or powered risers for peace of mind, at least. Nobody likes the smell of burning plastic.

That's completely wrong.

The cards draw about 25-50 watts on the pcie slot. They draw from 150-300w on the pcie power connectors. I've tested this many times with a variety of cards. The powered risers power the CARD, they run the fans, and the communications side of the gpu. I haven't seen a card draw more than 45 watts at full power through the power connector on the riser cards. Power boost has nothing to do with what the capabilities of the amount of copper in a motherboard trace can handle are. Six cards trying to draw 40W each is 240 watts, through a connection probably designed to provide 100-150. That's why people have problems, and that's why the powered risers are so nice.

PCIE specs dictate that a full sized graphics card pull up to 75w from the slot. Whether they actually do, I don't know. But it's there in black and white. Do graphics cards on a riser know whether they're plugged into 16x or 1x? If not they may try to pull that from the slot. Your findings indicate that they don't, which is good.

Electricity follows the path of least resistance, so once you plug a powered riser (or power boost) into the pcie slot it simply becomes part of the circuit. In that sense it's providing power to the pcie bus which in turn powers the card, not directly powering the card. That's why the power boost and powered risers accomplish the same task, even the the power boost is a standalone product that uses an empty pcie slot.

Hey guys, looking good!  Cool

Here's my modest machine, I use it for work and gaming as well as mining. My office is right next to the living room, and obnoxious whirring fans got the big thumbs-down from the wife. So I watercooled it.







Cards are 2x7990s, radiators are 1x120, 1x240 and 1x140. Case is a Lian Li midtower. The radiator fan shroud looks nice, but it does restrict the fans a bit. The mobo is an older model, and I had big stability issues getting it to run with 4 GPUs. I threw an EVGA power boost in the 1xPCIE slot and bingo, works perfectly. Individual GPUs are undervolted to 1.150, 1.145, 1.160 and 1.110v respectively. These are the lowest stable values I have found and it saves a few hundred watts at the wall compared to stock 1.2v.

Speaking of power, here we are pulling 1300w...



You'll notice my PSU is a Corsair HX1000. Funny thing about this power supply, it's actually a 1500w unit in disguise, but Corsair couldn't label it as such or else they'd lose the efficiency rating. I grabbed it for $70 from another forum member last year and have had no stability problems pulling 700w+ from each rail. The fan doesn't even spin up all the way pulling 1300w. I had it at 1450w for awhile before I undervolted the cards. The thing is a beast.

And the results are about 3.1Mh give or take, each core running @ 1100/1500. GPU0 runs the desktop, so it hashes a bit lower when the computer is in use. To game, I simply shut off one (or two). Interesting story about the VRM temps, when using the stock thermal pads on the EK waterblocks they were shooting up to 80 degrees or more. I replaced them with Fujipoly thermal pads and they literally dropped 20 degrees. I totally recommend them.

Happy (and safe) mining everyone!

Why are you people saying that bitcoin is dead and over? You do realize that Mt Gox is just a criminally incompetent bunch of fucktards attempting to hide their fraud, right? Bitcoin isn't dead, so stop with the FUD already.

They just want cheap coins, many of these guys probably own less than 5-10 coins and are desperate to increase their stash (which tells you how they really feel). Sad that many will end up with less than they started with.

Does anyone know how long it takes for a deposit from a local wallet to cryptsy takes? I deposited some MEOW from my windows wallet to my cryptsy wallet and it still hasn't shown up. This was over 12 hours ago. Here is my transaction info: http://kittehcoinblockexplorer.com/tx/020353a027b2a0dc82ddfaafab20db12aa6073d29887356a6e474e04222814e9

I'm not really sure what that all means so I was hoping someone could explain it to me.

mine took almost 24 hours to transfer. i would create a support ticket with cryptsy.

Yeah, Cryptsy is uber slow. Best to deposit 12 hours before you need it.

For Bitcoin to crash to zero a fundamental flaw in the code would have to be found or SHA-2 broken.

SHA-2 being broken is always a possibility.  Keep in mind that all public crypto schemes rely on a conjecture
for which there is no compelling theoretical argument or empirical evidence,

And there are many other developments that could make bitcoins worthless, for example

* The US government bans crypto-currencies.
* Everybody chooses to use Dogecoin instead of Bitcoin
* The Bitcoin blockchain stops being maintained because
** Mining becomes unprofitable
** Other crypto-coins become more profitable to mine
** It got all messed up and the network cannot agree on the fix

and so on.  Surely there are many more possible disasters no one has thought of.  (One year ago crypto-currencies were believed to be untraceable and un-seizeable, for example.)  That is why one cannot put a probability on "price will crash to zero"...

The nuclear industry once sponsored a very thorough safety study that examined all the ways in which a nuclear plant could possibly fail, and concluded that, assuming several hundred operating reactors, there might be one partial meltdown every century or so.  That was before Three Mile Island, of course.  According to the principles of that study,  three separate reactors melting down down at the same time would be less likely than a meteorite killing Santa Claus; and the possibility that an unloaded reactor could explode and become a major nuclear risk was not even considered.

NASA too once sponsored a very detailed study of the Space Shuttle's safety.  It concluded that the chances of a total loss were about 1 every 100,000 launches.  The actual rate turned out to be 1 every 50 launches.

As your interest in Bitcoin is purely academic and you presumably don't own any bitcoins, one has to wonder why the majority of your posts are in a forum thread consisting of mostly un-academic discussion between bitcoin owners.

To use an American saying, don't knock it 'till you've tried it.

Bitcoins main purpose is for money laundering and financing terrorism , almost everyone is aware of that. You can´t compare that to smoking marijuana.
People will go to jail in russia for 20+ years if they deal with BTC. Nobody wants to risk that.

in china, it seems people using bitcoin will be facing death sentence as well.

Definitely CONFIRMED.

Bitcoin plunges as major exchange halts withdrawals

http://money.cnn.com/2014/02/07/investing/bitcoin-withdrawal-halt/

Reading the comments, highest voted comments still think it's a scam/pyramid scheme etc. Good, I still have time to stack more coins  Grin Cheesy

When I try explaining Bitcoin to my friends, the first impression is always its a scam/pyramid scheme. I keep telling them not to come back crying in 10 years.


I usually explain it like it's a protocol to transfer value. Or a decentralized consensus system. That usually gets their attention.
1194  Economy / Speculation / Re: IF MT GOX DIES THEN BITCOIN PROBABLY WILL TOO on: February 08, 2014, 06:20:45 AM
Guys, are you living in a fantasy world?  I own plenty of bitcoin - some on gox, some on bitstamp and mostly w coin base.  I'm not trolling.  Regardless of whether gox's volume is decreasing, the bottom line is that bitcoin is always in need of new people getting into it.  If you think that mt gox going under is going to be a blip on the radar, then you are truly delusional.  Imagine the thought process of a new possible bitcoin purchaser:  "yeah, let me wire some money to slovenia or bulgaria after gox goes under" - hell no.  Trust of the major exchanges is critical.  If gox is a fraud, then this will be a huge crushing blow to bitcoin.  The fact that there are other exchanges doesn't mean s**t to the public. even though the underlying protocol is still sound, this is all about trust and faith - the very backbone of bitcoin.  bc without trust and faith behind bitcoin, there is nothing.   The vast majority of people thinking about buying bit coin will not do so if gox ends up being a fraud.  not everything written here that is negative about bit coin is trolling. 

Yes but we've seen much worse and lived to tell the tale. There are plenty of other exchanges that are trustworthy. Get your cheap coins now if you want them.
1195  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: February 08, 2014, 06:16:53 AM
I hope Gox works itself out. They always have in the past, sort of like a Phoenix when everyone thinks they're dead, they rise back up.

Anyone else remember when their trading engine would lag beyond belief? Nobody could trade, and the market crashed at one point because of it. THE END IS NEAR people were shouting.

The end was not near. This is still the beginning.

Interesting tweets from Kittehcointeam.


Our next release is so big that we needed a “paid” github account so ppl don’t steal our innovations before we launch them. No joke.

NO other coin does this, none. We will be the first. We are both incentivizing and gamifying a new ****** **** ****!


ALTCOIN/USD has been done, we got something even better than that Lips sealed


hmmmm Interesting..

Looking forward to this!

Guys, we need memes. I'm not great at making them but here's an idea. People love to anthopormophize their pets, especially cats, since we know they're secretly plotting against us at all times. When they're not kneading our stomachs (to check for weak organs), they're secretly planning their escape. One day, my cat will get out and "befriend" the family of squirrels living in the tree next door. It's just a matter of when. Kittehcoin could be our cats' chance for FREEDOM. Freedom from the oppressive humans, humans forcing them into lives of slavery, eating disgusting dry kibble and chasing fake feathers all day.

That's just one idea. You can really go anywhere with this, and Kittehcoin can make it possible. Marketing is not rocket science, just use your imagination Smiley

So, what will your cat do with Kittehcoin??

My wife works in digital marketing at a rather large firm (I wont' say who, but... Got Milk?) so I will pick her brain for a few ideas. I've been keeping her casually updated about the altcoin scene. She was skeptical about Dogecoin but understands why it's popular: It's cute, gimmicky, and has broad appeal. She did, however, think that a cat-based coin has more potential in the long run, and could co-exist right alongside of Dogecoin, if not surpass it in popularity. Let's get to work!
1197  Economy / Speculation / Re: What is your personal "oh shit" price? on: February 08, 2014, 12:15:56 AM
