Where did cloudhashing go ?!
WhitePhantom we need you back in !

Where DID cloudhashing go?  Haven't seen them at Bitminter for a couple of days.  Have they moved to a different pool?  I have contracts with them so am curious as to whether they're actually operational, or not.


Hi,

Because of the recent difficulty jump, the variances on Bitminter would be quite large. A lot of our customers (about 80%) are new to bitcoin mining. They would not understand the month to month variances so we had to temporarily switch to the Guild for a while. In September we have 110 terahashes coming on-line. The variance would not affect us with that amount of power.

We are very much still working with bitminter. Right now we have to do what serves our customers until the larger majority of our hashing power comes on-line.

Thanks

Emmanuel

Thanks for letting us know. So in September we can give the Guild a run for biggest slice of the pie.

I have a 3/31 Jalapeno that I did recently upgrade to 7 and I'm pretty sure by the time it gets to me I might be able to use it to warm a mug of coffee. That was a serious jump and we currently seem to be without WhitePhantom and CloudHashing  Undecided

As there are a few on Ebay now put some numbers on here http://mining.thegenesisblock.com/a/190e4d4536 (numbers for the 5.5 at list price and last months difficulty increase.)

At current difficulty increase a coffee warmer by March 2014. So I think that must mean that difficulty should stabilize before then as there will be no point anyone buying an ASIC.

The bad luck already happened, it's too late to hop.


That's the thing about bad luck, it follows you to the next pool. Smiley

If you meant BTC per MH/s per day, 0.042 is way above what LTC makes directly. Unless someone wants to prove my math wrong.

.02512 * 50 / (851.448 * 65536 * 65536) * 24 * 60 * 60 * 1000000 * 0.99 * 0.99

that's:

exchangeRate * blockReward / difficulty * secondsInADay * 1000000 * (1-orphans) * (1-rejects)

Mining LTC directly makes you 0.0291 BTC per MH/s per day

I agree with your maths, but I only got 2/3rds of that yesterday. As I said before there is no way of knowing why, if it is at my end or the pool had a bad day.

Today's profit is 0.0342 BTC per MH/s per day.

I've been mining this pool for 17 days with 1.4MH, and each day my payouts are substantially  less and are decreasing.  The last five days' payouts have been:

0.04572
0.03745
0.03897
0.00000
0.03146
0.02386

The last three days have not even covering my electricity, and less than mining LTC directly.  My payouts she be near 0.04788 @ 0.042 BTC/MH/s.

Thanks, the 0.02386 number for yesterday is in ratio to what I got, so it is not a small miner problem. I'll stick to the pool I'm already at for now.

Having a low hashrate in this pool is fine. The only drawback is that you have to have a 0.01 BTC threshold for a payout.

The point I was trying to make is that unless you publish the pools BTC/MH/day I cannot verify that by comparing my return to the pool's as a whole. It could be that small miners are disadvantaged in some way, it could have been a configuration issue at my end or just a bad luck day. I have no way of knowing.

It didn't work for me yesterday. I'm not complaining, just giving feedback.

I tried the pool out for a day and made a lot less than LTC mining would have.  I know this is a short timescale so I can’t read too much into that but having looked through a lot of this thread I’d like to just add my comments.

I do like the idea of the pool. Taking all the management of switching coins and currency changing for a reasonable fee is a service I would like to buy. It’s very much like buying a mutual fund, but I wouldn’t do that without seeing the fund manager’s track record.  A simple table of BTC/KH/day would satisfy this.  You could add comments about bugs and faults that may have cause bad days.

Having read much about VARDIFF earlier in this thread I don’t know whether or not that caused my bad results or not. But seeing the pool switch from coin to coin without my 300Kh miner having time to submit a share, I suspect I was losing out to miners more suited to the 512 difficulty. But I can’t verify that without a track record of the pool for the same time period, it may simply have been an unlucky day.
So add the track record and I’ll be back to give it another go.

It's not DNS it's a HTTP 500 error - (translates to "catch all the server don't work error.")

Mining is working but the website is down.

So we're mining something but who knows what?

How many blocks is Bitminter currently finding each day?
https://bitminter.com/blocks

Thanks. that's what I thought to look at before. Wasn't sure if it was the only way. It may not matter anyway for why I'm probing.

Looking at the account I use: I'm perplexed about why Bitminter is showing the expected (btc) per block at 60% of the value it should be if based on the ratio of GH contributed to the entire pool GH. For example, if you contribute 14 GH, and the pool is at 14 TH, then the ratio is 1/1000. Therefore, you should expect 1/1000th of each new block found in the pool (specifically 1/1000 of 25 btc = .025 btc/block). In the account I use, the expected displayed is 60% of the ratio it seems that it should be. I've always liked Bitminter, and the operator seems like a nice guy each time I've communicated with him. But this seems wrong. So, I'm either missing something, or need to find another pool.

My first guess is that it's a way to discourage pool hopping. However, I've been in the pool for a long time though. The only change has been to contribute more GH today. But should that really matter?

Late entry: Though the expected is creeping up slowly to what it should be. It's now at ~65% of the expected expected.

A quick look at my numbers shows I'm getting what I should be: it correctly calculates my hashrate of about 5.4 GH out of about 14.4 TH, translating to 0.0375% of the pool hashrate, and working out to roughly 0.0094 BTC expected per block.

Stupid question: you haven't had any recent downtime have you? The expected is based on the last ten "shifts" worth of work.

EDIT: Doh! You already answered my question for me. By adding new hashrate, it'll take ten shifts before the older shifts with lower values are removed from the average.


I see. Do you know what is the reasoning for this fading in recognition of contributed work, instead of just paying for work actually contributed each 'shift'?


This is on Bitminter home page:

"Reward System

Your work is recorded in shifts. When we create a new block you get a share of the income proportional to how much of the work in the last 10 completed shifts is yours. This reward system is known as PPLNS with shifts."

PPLNS is as you suggested to discourage pool hopping.

can be a real pain. I've never posted, yet I try to post this and the board says my IP posted less than 360 seconds ago? Odd.



Same problem here, very odd.
