Topic: [CLOSING] GHash.IO mining pool official page - page 31. (Read 149381 times)

I'm sure block 315694 with a 4+ hour duration didn't help luck 

10% below expected earnings falls reasonably within the limits of standard variance. Even 10% below for an entire difficulty period is reasonable.

Easiest way to calculate luck is to add up all the shares submitted and divide by the total number of blocks - if the number is above the current difficulty then luck is bad, otherwise visa versa.

1) Our pool statistics are fully transparent and available for you to see in real time in the Last Blocks spreadsheet. A simple way to determine how 'luck' is impacting reward is to monitor the 'Duration' column and over time build a knowledge of expected reward over a given time period. Block times vary substantial from one to another and hence 'luck' will come and go as for any pool. Calculated expectation should be a guide only it can easily be incorrect expectation.

2) We have 0% pool fee.

3) Luck comes and goes, we do not see any persistent problem in that area. There is no 'robbing.' Difficulty, changing pool size and your percentage of it plus luck are all parameters that will affect your reward.

4) GHash and CEX are a multi-service company. The 0% pool for independent miners is just 1 of our service offerings.

5) This is not currently on our development plan, but it will be fed back to development group.

ghash, since you are here, may i ask:

1) i have been experiencing around 10% less return than my hashrate suppose to get me.  is ghash experiencing low luck recently, or is there some other reason?

2) comparatively the 4% fee pps discuss fish pool can even earn me more .... your pool is suppose to be 0% fee right??? purely because pf bad luck??

3) your service is great, and i love mining with you... but now with this 10% persistent low luck... any way you can improve?? i will still stay mining with ghash even with 1~2% fee, but will leave soon if being robbed 10% without being informed ...

4) how could you maintain your great service with0% fee??  as the saying goes ... if it is too good to be true, it is ....... it really seems you are secretly diverting 10% hash power away from the main ghash network for your own good......  plx... just charge a fee and do it legit...

5) can you show pool luck on your home page?? 1, 3, 7, 30 days luck would be interesting to see.

Over the past few days there has been conversation relating to understanding payouts from mining on GHash.IO. We have just posted a blog on our website detailing how to read some of the data presented in our mining statistics 'Last Blocks' table. Hopefully it will help out some users.

Reading the last blocks spreadsheet:

When visiting the GHash.IO website, it’s important to make sure that you completely understand all of the information that is being thrown your way. There are a large number of mining statistics available to the individuals who wish to join the mining pool, and these stats can be helpful when it comes to gauging your investment over the long term. The “Last Blocks” spreadsheet on the GHash.IO will tell you everything you need to know about recent blocks that were mined by the Ghash.IO pool. Let’s take a look at each individual stat found on this sheet to make sure you know exactly what it is that you’re reading.

ID

The ID is a number given to each block that is mined by the GHash.IO mining pool. This is simply a unique identifier that can be used to reference a certain block at a later date. A block only receives an ID on the Last Blocks spreadsheet if it was mined by the GHash.IO mining pool. The IDs are handed out in order of when the blocks were originally mined.

Completed

The Completed column on the spreadsheet points to the specific time that the block was mined. This information can be useful when searching for a specific block that was found during a certain time period.

Block

The Block is another form of ID for the block that was mined by GHash.IO, but this is the block number as recorded by the blockchain of the particular cryptocurrency that is being mined. Ghash.IO does not mine every block on each blockchain, which means there will usually be gaps between the block numbers listed on the Last Blocks spreadsheet. The block number is useful when searching for more information about a specific block that was mined on a particular blockchain. For example, you can find out basically anything about a certain Bitcoin block by searching for the block number on blockchain.info.



Value

This column lists the block reward for each block. Although the block reward is predictable due to the transparent nature of cryptocurrencies, there are also transaction fees to think about when it comes to the final payout. Most miners will know the size of a particular block reward due to their familiarity with block reward halving schedules, so the most useful information in this particular field could be the amount of transaction fees that have been added on to the base block reward.

Status

The Status of each block is determined by the number of confirmations that it has received. Payouts are not made until six confirmations have passed on the blockchain. This is a safety precaution to make sure that the legitimacy of mining rewards are as secure as possible. The 120 number comes from the number of confirmations that are needed before newly mined bitcoins can be spent in the original Satoshi client.

Duration

The Duration column allows you to see how long it had been since the previous block that was mined by GHash.IO. This is not the amount of time it took to mine that one particular block, but rather the amount of time it took to attempt to mine all of the blocks since the previous block that was successfully mined by GHash.IO.

Hash Rate

The Hash Rate is the amount of hashing power provided by the GHash.IO mining pool during the mining of that particular block. This is not the network hashrate of the entire Bitcoin network.

Your Shares

This field is the total number of shares you owned during the mining of a particular block, as compared to the total number of shares available in the GHash.IO mining pool.

Score

Your score is simply the percentage of your shares of mining power as compared to the rest of the GHash.IO mining pool.

Total Work

Most cryptocurrencies are still based on proof-of-work, so the Total Work column is the amount of work output by the entire GHash.IO mining pool in order to mine one block. It should be noted that the work from previous blocks which were not mined by GHash.IO are also included in this number. Work is basically the number of computations run by the entire GHash.IO mining pool during the search for a block reward. The amount of work that is needed to actually mine a block is closely related to the current Bitcoin difficulty.

Payout

This is your personal payout from a particular block mined by the GHash.IO mining pool. Your payout should be proportional to the amount of the overall mining power that you own in the pool.

If there's a significant number of low power users it costs the pool OP time and money in maintaining a larger database which requires more powerful servers and each connection is still a connection.  Not to mention the coins need to be available in a hot wallet putting the pool at risk for a hack.

That's an understatement. Are you CPU mining?

Got like 0.0000008 BTC for the last 3 days... 

I guess my GHS is way to low. I might need to bump it a little 

Even happier now, latest 24 hours =  63 Blocks, 0.1119 BTC with 3.6TH. The impact of variance / luck over the past 4 days since Omarko was concerned about his apparent low return is pretty significant. I hope you didn't change pools....

No, calculators give you the expected average. But because of variance you don't get exactly that, but instead sometimes more and sometimes less. Unless you're mining at a PPS pool (if those even exist anymore).

Based on my set up I am getting similar to you, don't rely on calculators as they invariably give an upside expectation. Past few days there have been periods of long block hashing. I think I saw a 4 hour block in there at some point, but in past few hours a run of 2 mins, 5 mins, 8 mins blocks. The recent difficulty increase had an impact for sure.
EDIT: My stats past 24 hours 3.6Th approx 0.085BTC, 47 blocks. Divide by 4 for your 900 GH = 0.0212.
I'm happy with that return in the current difficulty.

This is as expected from my experience... try a differnent pool...

can someone answer my question please?

It was only like 0.002 lost.  Not really worth it for me to go through the work.  Hope it didn't sound like I was bashing them.

Contact Ghash customer care and create a ticket.
Also they have a facility to send sms code for authentication.

Totally lost my account there when my phone factory reset and I had my google auth set up.

Thanks for the reply.  Unfortunately, the cex.io support page is not working properly.  As i said, it will launch but it just keeps prompting you to login over and over again even though you are already logged into cex.io and have clicked on the support link at the top of the cex.io page.  From the screenshot you can see I'm logged into cex.io on the background page and the foreground page is the support page and it redirects you to the login page even though you are already logged in and it never lets you get passed that.  However, each time I enter my login it does send me an email telling me I had a "successful authorization".

I am not sure I am getting fair earnings on Ghash, can someone clarify this for me please (sorry I am new to this) :

average hash speed 923gh/s (according to 1d statistic on Ghash page).

earnings:

7/8 - 0.01988 BTC
8/8 - 0.01822 BTC

I would have thought I should be pulling around 0.023 at current difficulty per day which is quite a difference.

Can someone enlighten me on this ? Why are my payouts so low ?

Hey ldh37, servers are all functioning ok and support page is up, please try again. We do have issues relating to auto payout threshold, which is probably what you have been affected by.

There's a lot about Ghash that looks broke but what do you expect ? Every time you turn around they're tweaking something.
