Edit: I can't believe CEX price is not going seriously down, it's only day and a half until difficulty change. What happened, why are people not selling in panic 2-3 days before diff change like before?
im confused abut this as well...

im confused abut this as well. i expected the .12 peak, but i was genuinely suprised when the market moved beyond that and even touched .14 with brief support. rode from .083 to .095, got off, got back on at .099 and rode til .118. i want to reenter but the price is much too high at the moment/violates my internal rubric for purchase.

when it does crash (current selling pressure + thin buy side) it will be messy.

and i will sift though the rubble and hash again.


just takes one panic seller with a large enough position to bring it all down.

Let's assume for the sake of the discussion that what is alleged to have happened did actually happen. What would be the benefit of doing such a thing? Are they alleged to have 'won anything' while supposedly gambling or was the act more of a 'flexing of muscles to see what was possible'?

Considering that their bets were almost exclusively wins as a result, and they bet on 36% a lot, their profit was considerable. Well, they likely emptied Betcoin's hot wallet.

I suggest anyone reading about their pool's questionable behavior before trusting them your money.
https://bitcointalksearch.org/topic/ghashio-and-double-spending-against-betcoin-dice-321630

One thing you didn't explain is why would somebody use giant with 25% of network hash rate to do the simple thing like double spending on 0 confirmation transactions, he just needed to put the nice TX fee in later transaction and it's done.

No, you can't double-spend easily by just putting a higher fee. Transaction replacement is disabled in the reference client, so once the transaction is broadcast and is accepted to nodes mempools, the nodes will reject double-spends that come later.

That's why you still need hashpower to include double-spends into blocks.

How can you include double-spends into blocks when your pool mines no blocks, as you claim? In which scenario mining pool gains anything with hashing whose results are never included into blocks?
I didnt say pool mined no blocks, I said they didnt mine any to their address. Supposedly they used different address which I mentioned in my post.

I noticed that period 25th - 27th September you mentioned on the other thread and wondered what had happened. I rather naively thought it was just bad luck but was surprised as I also mine with BTC Guild and although there can be erratic patches, in the time I have been using BTCG, there hasn't been anywhere near that amount of time passed without a block being found. Quite the opposite really, BTCG is very smooth, even for PPLNS

Like some of the other commentators above, it's sometimes hard to take seriously some of the price movements on the CEX order book. Whilst there's no way to tell for sure, it feels that someone is playing both sides of the ledger.

It would be good to hear an explanation from the company, something longer than just a couple of lines of rebuttal. Your analysis really does require addressing by CEX as it's all out there in plain sight and if there is diversion of client hashing for nefarious uses, it's completely distasteful.

Perhaps CEX needs a genuine competitor to 'keep them honest'?

Price flirting with .12 today...I personally sold off my shares @ .116 since I didn't think the upward trend would continue. Will probably buy back in if the price goes below .11 again.

WTF man... Price is hovering near 0.11 BTC/GHS.

I see a good resistance at BTC0.10/Gh/s i think it will be great time to trade before the difficulty rises. Also we will see a surge of selling before retarget. Great time to wait.

 New ASICMiner gear coming online in (heh) two weeks (30-~38GH@ 1.99 BTC) sets the price of shares @ 0.6 BTC/GH.

 Expecting the price to drop any time now below 0.1/GHs

Also Avalon is selling in-hand ASICs for 30BTC / 750 GHs (see here), estimated additional price to produce working miners is around 20 BTC (burnin is testing the prototype in a few days). 50 BTC / 750 GHS = 0.06-0.07 BTC/GHs. They are less efficient than Bitfury chips so you have to add electricity price to it. Yifu's reputation aside, this have to affect the GHs price a bit.

Still, it's certainly better than just letting my coins sit around in the wallet and gather digital dust all day long Tongue

That's debatable and completely depends on whether you can get rid of the shares before they tank too much in price.

That's a very pessimistic viewpoint. Also, since shares inherently generate value through their mining power, they would have to drop dramatically in price for me (and other users, for that matter) to not break even at least.


However, I perhaps should have phrased the above differently. It's certainly more interesting than just having coins sitting in a wallet, but I see your point about the potential for loss.

Bought in today at 0.10784898 with some BTC I keep around for short-term ventures. The concept is interesting but I'm somewhat skeptical of the whole operation; No offense intended to the admins of CEX, but I'm slow to trust anything BTC-related after the many scams that have rocked this community. The fact that the difficulty has been rising so rapidly over the last 3 months also has me concerned about the long-term value of the shares I just purchased...

I'm waiting when the price for GHs goes down. It's really high.
