Topic: Anyone mining at ghash.io ? Any anecdotes ? (Read 10907 times)

They have 8 orphaned/rejected blocks out of their last 18

Besides having more than a share of the mining power right now, In my opinion their support is rude.
Still don't like their withdraw fees either.

No, exactly, and at this point, it seems like the operators have enough market power though to fix the market, allowing more people to buy in at the ~0.007 price...

I have been getting a massive amount of duplicates mining BTC the last few days.

multi.ghash.io has been down since approx 1PM BST today? Just me?

Cpuminer has fallen to my backup pool but keeps probing multi.ghash.io for life every other minute. Keep getting "stratum_recv_line failed" on multi.ghash.io

Edit: their support says:


Edit 2: appears to be back online now (4PM).

Yeah I am starting to think that the cex.io system is rigged or just dominated by stupidity. I think it even astounds the cex.io people because they would have priced the May shares much higher if they thought the market would have accepted them.

Currently trading at a 15% discount to GHash, and pays the expected value automatically...just sayin'

Like in real life, I keep my mining claims secret

GHash is a good fallback pool for when the main line goes offline.

It's not profitable because there's too much hashing power for smaller players, under 1TH to make a a comparable ROI as with other pools.  Where I make BTC0.022 with BTC Guild, I make BTC0.0200 which is a 0.002 difference.  After 10 days, you give a whole days hashing for free to GHash comapred to BTC Guild, which I don't mine there anymore either, their stats are boring but probably have the most robust website.  You do get more venues to make money with GHash's merged mining but no one uses anything other than namecoin from merged mining it seems.  The stats at GHash are mostly live but so is BitMinter, who's interface makes Ghash look like it came out of the 70's.

I keep GHash as fallback because I know it will take a lot for them to fail, I can promote as an affiliate and make money trading hashing power.  Although all I want to do is hash with my own equipment, I like the fact of multiple income venues that are available to me.  However, it doesn't warrant the 0.002 daily loss vs. other pools with much lesser hash rate.  I don't mind waiting and get my electricity's worth. I did this test 3 days on 3 random days within 1 week.  They were all the same results so luck has no effect on this test because each has the same chance to get the same (mal)chance as the other.

I also won't promote GHash nor CEX.io, they're too big, I also won't promote anything that doesn't pay me, so....  hint hint other pool owners, offer miners an incentive to gain and keep them.  Don't wait for me to release a pool because I will have one in time and will blow everyone's mind, that's how CEX.io became huge, get affiliates to do all the heavy lifting for you and offer state of the art interface.  

Now I can't change difficulty on my workers 

I had a temporary issue connecting as well. Its too bad no one else merge mines so many other coins. Well, there is mmpool, but I don't want to wait 10 days for a payout.

I'm new to the environment, what do you mean by low returns? GHash is the biggest pool.
Where do you mine? Eligius?

I used it for a while but returns were too low for my liking.

Stats reporting are probably the best though.  Live stats of your miner's GH/s rate.

It's not bad, not great, was not profitable for me.

I am on uk1.ghash, seems to have been an issue but only for some minutes, operating normally now.

Anyone mining on uk1.ghash.io? I just got kicked out and cannot reconnect

They seem down at the moment. Pool speed under 1/20th if their usual.

Does anyone know if its possible to set up idle worker notification on this pool?
EDIT: yes, it is.   found it in the dash options somewhere a few days ago.. can't remember where!

Also I'm a bit puzzled by the concept of multi-coin mining.. if its more profitable than straight LTC mining (and allows auto conversion to LTC for the payout), then what is the point in straight LTC mining?

I heard SXC has been corrected and paid out yesterday.

I am enjoying my experience at Cex.io quite a bit, I moved from BTC Guild and my revenue shot up. The pool speed is now over 22 PH/s and we are finding blocks rediculously fast. One day we had 9 in a row... talk about luck. I had a record $15 day with 2 Antminer S1's and a couple dozen cloud GHS.

I post for free  

I use ghash with Antminers, that's what I post about as that is my interest. Oh just looked at your history 10 of your 20 posts are hate posts on CEX - give it a rest. Yet another hater shill 

10 of your 20 posts are about how wonderful cex are - give it a rest. Yet another cex shill. 

Ghash is definitely worth mining at. Is it your ISP or your own router / firewall that has blocked ports? If you can identify that then yuoucan fix it.

It is worth mining at this site, the overall experience is very good, but unfortunately my ISP blocked port 3333, what makes me very depressed.

Multipool mines SXC but for me comes nothing out of it?
LIst continues an continues... Doge, LTC and others pays ok.

I mine BTC at ghash and it works very well. Rewards are paid on block completion, DOGE blocks can take hours, block 202076 ran 12 hours perhaps your timing was just unfortunate during that block.

I pointed my 5 MHS at doge.ghash.io:3333 last night and been mining for 12 hrs now. The real stats are fine and hashrate is what it is, but strange thing is I did not earn a SINGLE DOGE yet. My balance shows 0.0000000 DOGE and that's for 12hrs of mining. I don't know what's the catch with them but I am going back to my tested pools.

My advice for ghash.io is stay away!

Must have been some blip. My hosted miners went down to 31MH/s, then 2 hours later came back at 26GH.  I only have 10GH.

I still cannot reach the worker or finance pages, the homepage is a cloud flare cached copy for me.

They did solve a block 9 mins ago at 702TH so 250TH missing.

seems like my hashes aren't working right now , as per GHASH ( cex.io based ones atleast )

I had 2 more dips shortly after your post and ghash.io is down again ! Going to the cloud flare page, with my secondary pool notification email

On a lighter note, I went through my daily average hashrate, and multiples by the ideal earnings (plus any PPS from my secondary pool)

The earnings for the past 11-12 days have been within 98.5% of ideal income, despite the disruptions and the presumed network problems with consecutive stales, etc

Ghash website down for the last 40min or so
Email notification that my miners hopped to their secondary pool.

As for anecdotes, read this

The sky is not falling, but ghash.io is down again with the cloud flare error

According to the email I just got, a server popped a DIMM rack in their data centre.  Downtime again later to replace the broken bit.

The sky is not falling. 

They are not DDoS'ing BTCGuild.

They are not ping flooding the NSA.

There was a significant drop in pool hash rate today



And since 29th Oct, my miners have hopped to their secondary pool with 3 dips in hash rate



On their forum they report being under DDOS attack earlier this month.
https://cexio.zendesk.com/entries/27168173-ghash-io-is-under-DDoS-attack-SOLVED-

I've been playing with cex.io a bit, mostly because of how easy it is to turn a quick profit in speculation/manipulation.  I've noticed these, and I'm going to *guess* they are actually related.

1) Downtime is *probably* due to attacks [my guess is they're just overloading the webserver, not actually a bandwidth saturation ddos]
2) See #1

3) Failing over to secondary pool is probably network related (NL servers aren't always the most stable in my experience).  Could also be attack based, or even just growing pains since they never really operated a public pool before.
4) The mining server offline and several stales would be related to #3.
5) Also may be related to #3, but also: VARIANCE.  Even at 800 TH/s, 3 hour blocks aren't that uncommon.
6) My guess:  GHash.io's internal speed is in the ~600 TH/s range.  The remaining ~200 may be other miners, or personal miners of the people involved with ghash.io (BTC Guild has a miner that comes & goes at over 100 TH/s, might be using ghash.io as primary since they don't show up on any major public pool when they're not on Guild).  When they drop from 820 to 600, that may be their public pool server failing, either actually crashing, or simply not communicating with their backend properly.


All of the above are guesses, but they're educated guesses from someone who has been running a pool with multiple servers in multiple regions for 2 and a half years.  A lot of the problems you mentioned are extremely likely to stem from the same cause.

- Lots of downtime in the past 5 days
- Currently ghash.io and cex.io offline (cloudflare) again for the 2nd or 3rd time
- Approx 3-4 times my miners have hopped to their secondary pool
- Multiple times I think their mining server goes offline, several stale shares in a row (5 stale blocks out of the past 100)
- Whenever I see a very long blocktime (5 hours at 800GH/s 880TH/s is a very long time) I wonder if their backend is down.  The consecutive stale blocks were a 3hr stale, a 1 hour stale, followed by another 3 hour block
- Large swings in hashrate, from 820GH - 600GH - 820GH

I can't get my RPi to work very well with the pool running Minepeon

GH is currently overpriced, take this into account:

I took the plunge a few days ago, and am going to play around with reinvesting mined BTC into GHS, and see how that works out for a while.

Interesting site.

Thanks for your input.

It's a double-edged sword though. If you want to keep your payouts separate from your 'trading' money, it's not a good idea. It muddies the waters for trying to track profits. If you aren't going to do much trading, and you don't care about tracking stuff, using the same account will make life simpler. You can use the link in my signature as a thank you as well. 

For those who don't know how to register on ghash.io - just register on cex.io and you will have same account for both sites. You can use link from my sig as a "thank you".

Pool seems stable for me.
I make more coin by buying/selling GH/s than I do mining though.

Can usually get a 5-10% movement per day without having to watch too closely.

I did see a short ~10min outage. unlike that happening to my home rig. CEX.io rased by GH/s for a few shares until my hourly ave went back to my purchased level. So no BTC lost.

I jumped in with them a few days ago when you could buy 1G/h @ BTC0.07 - it was a steal. I'm tired of paying over the odds for hardware that's obsolete by the time it's delivered/plugged in - then having to pay electricity for the privilege, especially now the electricity cartels/companies have just increased their prices here in the UK - AGAIN
If they stick around I'll be tempted to sell all my mining hardware & deal only with them- it's slowly turning into a money pit this mining lark.....

Edit: They've also been rock solid in the few days I've been with them also - can't fault them tbh.

....


Really?  Who knew? 

They are now 0% but merge mine NMC and keep that for themselves as payment from what I can gather.

It used to say 3% it correctly says 0%. the 3% is old info 0% is correct now.

just remember this is separate from the mining you can buy at cex.io you are just using it like any other pool.
As you can see from my sig I mine elsewhere. 

So this is lie on the top of the ghash.io page:
Pool fee is 0% ! However, we have NMC merged mining to cover pool expenses.
 

There are much cheaper pools...

spiccioli

It was said somewhere in the russian part of this forum. I don't remember where, As for connection problems - I have no idea, I switched to Eligius. May be it is under DDoS just now.

3% PPLNS, Transaction Fees are paid to miners

I'm using nl1.ghash.io, but I just tried us1 and it has the same delay.

they have two pools to connect: us1.ghash.io and nl1.ghash.io, both supports stratum. Check the settings. (just ghash.io is only the web interface)

Where do you get that? They list the full block rewards including transaction fees in their block table. Unfortunately my hashrate is too low to calculate accurately whether there is a fee or not, since the percentage of my shares relative to total is truncated to two decimals. Someone with 1% or more of the pool's hashrate should be able to calculate how high the fee is with a low enough error margin.

There is a strange delay when connecting to the pool after restarting BFGMiner. It will take up to 5 minutes until the pool is marked alive. I'm curious if this happens with other miner software.

2% or 3% fees. this is the only anecdote.

 Recently created an account on cex.io and thinking of pointing my boxes at ghash.io.

 Any issues to speak of ? Good or bad stories ?
