hey , please could you stop thoses fuckings bots order with 0.02 btc and no limits to hash who always appear to up the price of rent ...

its horrible , i can't leave pc 5 min without this happen ...

i talk about nicehash.com / scrypt ...

You have 2 solutions:
1. Place fixed order and you will not have to worry about any bots any more.

2. Use bot on your own: https://github.com/nicehash/NiceHashBot and you will be able to leave the PC Cool

I sent on Thursday 0.02006618 BTC and it going back to me, because i sent the transaction without fees.
I sent today 0.0210317 BTC and i can't see this in my account.

You have updated to the new wallet right?

This should not matter. When pool rolls out new diff, this diff is used with new job - official stratum mining specifications say that:

Quote

This means that difficulty 2 will be applied to every next job received from the server.

If the pool does not respect this stratum rule, you may get lower hashpower.

Slush mentioned it here too:

Problem with submitted shares not matching what i paid for.

I verified the orders i submitted yesterday and today for the amount of shares actually submitted to the pool and they are at least 20% off. Which means i am paying 20% more for the hashrate i hired.

Has anyone else had similar problems?

Here follows my calculations:

Order	Price BTC/TH/Day	Total BTC	Unspent BTC	Limited TH/s	Expected Shares	Actual Shares (on pool)
Nicehash
#252158	0.0103	0.205702	0	100	401749338.9
#250693	0.0104	0.156702	0	250	303106382.5
Total nicehash					704855721.4	560946737
WestHash
#250694	0.0104	0.303702	0	250	587446328.5
#252159	0.0103	0.156702	0.05561814	100	197423330.5
Total Westhash					784869659	668995673

Has anyone any idea what happened? Can i get my missing shares refunded?
Thanks,
girino.

i would suggest to use only one fixed diff on the pool
( can be really high, statisticially this does not matter )
i also had problems with vardiff .. this is why:
nicehash sometimes sends "old" shares ( from slow miners ) when diff changed, but block did not change. this leads to two problems:

a) when diff is doubling:
50% chance to be below new diff = get rejected
50% chance to be above new diff = get a share with 200% diff
so this case should be no problem on average

b) when diff is halving from 2048 to 1024:
100% to be above new diff = gets always accepted
but: nicehash thinks the share is worth 2048 , whereas the pool thinks it's worth 1024
so you will pay more than you get.

so i expect a often changing diff to cause problems!
i set diff to like 65536 ..only few shares are submitted, but each has a high value..
so i reduce network load, reduce pool load and avoid those problems!

WhirpoolX algorithm added

You can already place orders for WhirpoolX algorithm.

You can download sgminer with whirpoolx support here:

https://www.nicehash.com/index.jsp?p=software#whirpoolx

MULTIALGO note:
WhirpoolX is disabled on multilago by default (because currently you have to use a special sgminer fork and the transition will probably take a while). But nevertheless if you want to use multialgo you can still use it by manually adding WhirpoolX factor to your pool's password setting, for example:

"pass" : "f0=0;f2=0;f3=8.5;f4=4.5;f5=500;f6=3.5;f7=14;f8=0.35;f9=1.25;f10=135",

(as always, remember to add this to ALL your NiceHash/WestHash pools entries, not only for the new WhirpoolX entry).

p.s: we haven't tested sgminer-whirpoolx fork with other algorithms

Where are now all the arbitragers? Scrypt price on NiceHash/WestHash is wooping 46% below litecoin price. You can earn a lot by just doing arbitrage between NH and litecoin.

I believe they updated the 'fixed' price so it can't go lower than the 24 hour average?

I don't need to refill yet because the price is too high so my order isn't being mined right now. For some reason Nicehash has always been pretty slow processing payments but they always get there in the end. Usually I make sure I've got a surplus.

Nobody will loose any coins. We have mailed private keys of old deposit addresses. If you sent to old address, just use that private key to recover the coins. If you didn't get private key, contact our support and we will mail you the key again.

That is not bad luck … I paid for something and that was not delivered …

I really don’t don’t want to step on anyone’s toes – but honestly, sometimes it’s just too funny to notice a “senior member” not grasping the most basic things.

QFT.

A lot of us are complete idiots Tongue

(Not me of course, I'm a genius which is why...)

I sent some BTC to my wallet just after the switch to MultiSig, please let me know if it'll be possible to retrieve these coins. I've PM'd the OP.

I'm glad you cocked it up. I was about to send some btc over. Now updated the address so I don't lose any.

It is called bad luck. Miners have to be "lucky" to find shares. And higher the diff, the more luck is needed. I think someone good with statistics can actually calculate you the odds to have 20% difference.

For the probability of that ocurring, since you mentioned that, someone corrects me if i'm wrong, each share is independent and has an uniform probability of meeting the difficulty set, so we are talking about a binomial distribution with the following parameters:

N = number of produced shares
P = difficulty_of_shares/target_difficulty
K = number of accepted shares

Considering that you only pay for valid shares, and you say they are of difficulty 128, and that my target difficulty was 12000 most of the time, we have:

N = 784869659/128 (since you are paying for shares with difficulty 128)
P = 128/12000
K = 668995673/12000

This number is so small that it i have been unable to calculate it precisely. But i made a simulation with much smaller differences, ranging from 1% to 5% that you can see bellow.

%actual shares	N	K	Probability
99.00%	5226528	55192.13568	0.008762397104
98.00%	5226528	54634.63936	9.52E-07
97.00%	5226528	54077.14304	4.14E-13
96.00%	5226528	53519.64672	0.00E+00
95.00%	5226528	52962.1504	0.00E+00

As you can see, with a difference of only 3% the probability is already so small that you should already be suspicious if it occurred, with 4% it's already not representable by a double precision digit.

Now, we are talking of a 20% difference. Please, do not blame luck. Luck was not involved here!
