Anyone else having problems with bought Ghs not Hashing?

Got 12 Ghs that arent Hashing!

Hardware failure?

[JayCoin]

Same Here. Purchased GH/s been offline for over an hour.

[pcotter]

Back to normal... Hashing away!!!!

[pumawolf]

has    btc/usd  per g/h   ever been price at fair market value or has it always been this off from the beginning. i understand u can sell the shares anytime so i expect it to be slightly higher,but something about this seems way off.  is it more worth it for me to buy a rig/usb to mine with and then sell it on ebay?

Dear CEX

Please could you outline your plans to mitigate against your pool becoming too big?

This is a matter of great urgency to the community.

Here is an example of a mitigation plan that was mercifully never needed:

And that is just what they are reporting, who knows if their farm is mining on other ips as well.

I mentioned they got 1/3 network control 2 days ago, now it has hit 40% and more people are now expressing their concerns. As their network share increases we will see more people mentioning this issue. Worst case scenario: this issue hits news sites, people start worrying, exchange increases confirmation time leading to panic and I guess we all know what could happen next. Im not even mentioning cex.io doing malicious activity with the network control they have which they could. Im not trying to cause panic and I really hope nothing bad happens but if it does then we will just to have endure and learn from this. Maybe im just paranoid but this cannot go on for bitcoin to survive long term.

whoever havent read this please do
https://en.bitcoin.it/wiki/Weaknesses#Attacker_has_a_lot_of_computing_power

An attacker that controls more than 50% of the network's computing power can, for the time that he is in control, exclude and modify the ordering of transactions. This allows him to:
Reverse transactions that he sends while he's in control. This has the potential to double-spend transactions that previously had already been seen in the block chain.
Prevent some or all transactions from gaining any confirmations
Prevent some or all other miners from mining any valid blocks

The attacker can't:
Reverse other people's transactions
Prevent transactions from being sent at all (they'll show as 0/unconfirmed)
Change the number of coins generated per block
Create coins out of thin air
Send coins that never belonged to him

From my own charts and using my own metrics the price is about fair at the moment.

However, the price trend is always down and you will never mine enough Bitcoins to cover that loss. Still, it doesn't seem to stop the many idiot juveniles that use the site. Think Satoshi dice but with loaded dice and you don't know which number is biased.

Even since the days of GPU mining the price of hardware per hash has fallen constantly. That is why the value of GHash on CEX is always trending downwards.

Whatever you buy now will fall in price. What price a 1GHash GPU based rig now?

From now I would say just about all (and most definitely all cloud based) mining is a loss making proposition. The only way you will profit from mining with your own rig is from price appreciation of Bitcoin. You will never profit from cloud based mining.

Sorry to double post this PSA..  reddit has not managed to turn the tide.
Still growing, pool speed up from 4.16PH to 4.61PH over last 2 shifts (8 mins each).  Perhaps they'll reach 51% by the weekend ?

Looks like CEX is trying to corner the market from many directions, doesn't it?

Through mining or a rigged trading platfom.

From Status Quo's "Down. Down. Deeper and Down." To The Who's "Anyway Anyhow Anywhere."

[tiberiandusk]

I am also questioning what cex.io does but many people are just going to learn it the hard way.
I see referral links everywhere, youtube, forums etc and I feel sorry for those who fall into this.
Many people think they can get rich quick and they have only themselves to blame for not doing research.

I visited cex.io from time to time to see how it does and I saw the drop from I believe 0.08btc/ghash to 0.03btc/ghash. It did not fall slowly, it dropped like a rock which could be a manipulation.
There are a lot of bagholders or should I say hashholders in cex.io which will not get their initial investment and I hope they learn from this. We are in very early stage of bitcoin, things are unregulated, and people are being scammed everyday. Nobody is going to save your assess if you lost your bitcoin to scammers. I am not saving cex.io is a scam but that place sure is fishy.

If you want to trade to increase your btc holdings, it does not make sense trading at cex.io. btc/ghash will only devalue over time, you might get lucky from time to time but once the next dump comes ready to say goodbye to your investment if you are not prepared.

Agreed.

I believe that GHASH.IO is as legitimate as any hashing site but that CEX.IO is an ingenious way of getting people to keep their hard-earned Bitcoin on the site with the chance of them gambling it away to CEX.IO

CEX.IO also lures in those without hashing hardware to gamble their Bitcoins too.

At least with Satoshi Dice the game is zero sum. It is not a zero sum game on CEX.IO when CEX.IO is self-regulating its own exchange for its own commodity. A commodity which is constantly trending downwards in price and CEX.IO is the only agent able to short sell that commodity. That is insider trading and in any other field would be ILLEGAL. For a company purports to be based in the UK, I wonder why the Met has not raided it yet.

Ghash.io is reliable? Haven't they been double spending?

[Light]

Ghash.io is reliable? Haven't they been double spending?

I've personally never heard of any reports of them double spending, just people panicking about the possibility of them doing so should they gain more than 50% of the total hash rate. I'd think there would be far more uproar if there was proof that they had actually used their power to create double spends.

I dont use cex.io so I cannot say if it is profitable or not but lets do a simple math using the data above.

Say you got 10ghs on 5th Nov 2013 at 0.10710000btc/ghs totalling 1.071btc.
You let it mine for a month with difficulty 510929738 and got 0.2953btc. I assumed the difficulty does not change so the amount will be less than this.
Then on 5th Dec 2013 you sold your 10ghs at 0.07399962 totalling 0.7399962btc/ghs.
Your profit will be .7399962 + 0.2953 - 1.071 = -0.0357038btc.

I picked the date at random and data for difficulty I got from http://bitcoinwisdom.com/bitcoin/difficulty
It does not look like a good investment to me. You could increase your btc holdings by daytrading but I wouldnt call daytrading an investment.

Decide for yourself whether it is worth risking your hard earned bitcoin and bitcoin network security
Thanks JayBee66 for the historical data.

[skuser]

I just don't get why everybody is crying about how economically disadvantegous it is to buy GHs at CEX.io and at the same time are people buying hardware at much higher price per GHs like Antminer U1 here https://bitcointalk.org/index.php?topic=386170.0 . Am I missing something?
Of course GHs price will go down with rising difficulty, but this has nothing with cex.

[Macno]

why does Cex/Ghash not respond to all that 51% panic? It`s what worries me the most.

[Technomage]

why does Cex/Ghash not respond to all that 51% panic? It`s what worries me the most.

Maybe because they don't care about anything? Ghash, the pool, has demonstrated that unlike other major pools it will not create blocks larger than the default size, which is very short sighted selfishness. It has used hash power to do double spending. It has not cared about the pool getting closer to 50% hash power.

Bottom line: the boycott of Cex/Ghash is for a good reason.
