Please, when you are saying about rejects, state following: what kind of rejects are you getting (share above target, duplicate or stale), your mining software and location.

I'm using Hashra Mini Controlla 1.4.5 (latest) located in central USA.  I have 10 miners each at 850 Mhz and currently am running at 48.09% rejection rate.

Important note for all sellers - providers

After extensive internal testing we can finally provide you with our own sgminer and cgminer builds.

As you probably already know, NiceHash is using some advanced stratum protocol features, therefore older mining software is not supported. We have prepared optimized sgminer and cgminer builds for you to get optimum performance when mining with GPUs on NiceHash. Of course, these builds will also work equally optimal on other pools.

Our builds includes patch for seamless order swaping without interupts, the idle bugfix as well as some other minor impovements.

Get the software here: https://nicehash.com/software/

Please, download our sgminer or cgminer binaries and please report if it is working well for you. We will apprechiate any feedback!

On our software download page you will also find links to latest BFGMiner builds with good GridSeed support (BFGminer 3.99.0) - hopefully Hashra and others will include the latest BFGminer in their software builds as soon as possible.

Thank you for using NiceHash!

Yea it looks like someone must have exploited the site as why would the price double there are other places cheaper. Has me a bit paranoid atm wondering wtf is going on.

Yesterday, or two days ago I observed a pattern. I don't know if it's an exploit, hack, or just someone stupid but it goes like this:

1) If the top order paid 5.00 (for example), someone create a new order of 6.00 (it was not exactly 1.00 more but it was definitly higher. As a buyer you would first try with 5.10, no?).

2) Wait for the order to become alive and miners start to work on it.

3) Cancel the order after few seconds only. (no, the order did not become dead before he cancel. So it's not someone who have trouble with his pool)

4) Repeat.

5) ? ? ? ?

6) Profit    (sorry, I could not resist   )

But seriously, I don't know what was going on and why someone would do that....  

hmm, interesting ....

when can we use cgminer with nicehash? my hosted miners at gawminers.com is showing 100% reject rate

[kenshirothefist]

Now that we've fixed GPU-based sgminer and cgminer compatibility (https://nicehash.com/software/) we'll focus on GridSeed as well as on other ASIC miners (A2 Miners, Zeus miners, Lunal Lander, KnC Titan, Alpha Viper, etc.). Source code is ready, we just have to patch some of the popular forks (like https://github.com/dtbartle/cgminer-gc3355). We'll also make sure that hosting providers will use mining software that is supported with NiceHash (we're in contact with hosting providers). Stay tuned.

I'm mining at another pool and using nicehash as reserve pool, it's in settings of my main pool web page. Before everything worked fine and when my rig had no job at my main pool it was switching to nicehash. Now this option stopped working today and their web page shows warning:
 "This pool (meaning nicepool) issued a client.reconnect which is incompatible with our service. In order to keep our system from getting banned by the remote pool (nicehash) we've temporarily disabled this connection"
I've got a question to support or developers how can I make it work like it was working all time before today (I'm using sgminer 4.1.153 from the start of nicehash).
Thank you.

Update to NiceHash sgminer and reconnects will not happen.

I would rather prefer if payments (for providers) be made only once per day.  With the current rates, having payments 4 times per day only produces dust (or near-dust) for 98% of the miners (that is, everyone apart from the top 15 miners with huge hashrates), and so we will all end up paying huge tx fees for using those btc in the future.

kenshirothefist, would changing that be something you could consider?

Thanks for all the rest of the good work!

This afternoon i have a strange log message :

[17:23:30] WARNING: POTENTIAL CLIENT.EXPLOIT!
 [17:23:30] Reconnect requested from Pool 0 to stratum.nicehash.com:3333
 [17:23:40] Waiting for work to be available from pools.

Any problem on the pool ?

I'm getting lower hashrate than what I'm used to with either sgminer or cgminer on windows. around 12% less. I tried all the kernels, no difference. any clue?

[mac-coin]

So what got fixed overnight,  nothings changed me end

[mac-coin]

Regarding placing order,  Could we have a feature added so we can create a new order based on an old order.

[BitcoinGeekBoy]

Or be able to save different pool info so we don't have to re-type and re-configure the pool info over and over for each order.

when will gaw hosted miners be able to use nicehash?

I'm not seeing NiceHash deducting a transaction fee.  They deduct a 2% mining fee, but other than, I'm getting the full remaining balance in my wallet.

The tx fee you will have to pay is when _you_ will want to spend all those mBTC you received.
You pay a tx fee per KB, as well as an extra fee is the coins are too young, and if the inputs are "dust" (very small).
That is to prevent the network from being spammed by sending the same 1 bitcoin back and forth millions of times, or by sending millions of tiny transactions.

For the Bitcoin Armory website:

Sending less than 0.01 BTC to any recipient — The network considers these small outputs to be “dust,” and discourages them by requiring a fee. If it was not discouraged, someone could take 1.0 BTC, and create 1,000,000 transactions of 0.000001 BTC each, for free, which would clog the network. So, that's one definition of dust.

If you have received lots of "dust" and try to spend it, you will end up paying ridiculously high tx fees, which can even be over 75% of the amount of bitcoin sent!

Here is a good site about bitcoin fees, and how they are calculated:
http://bitcoinfees.com/


TL;DR:  We all really want to avoid receiving lots of dust, because *we* will pay huge fees when trying to use (spend) those bitcoins afterwards.

I'm not sure I understand your concern. One input contributes 148 bytes to the transaction size. You can have up to six inputs and still fit within 1KB and pay only the default transaction fee. FAQ states "Payments are issued four times a day if your unpaid balance is greater than 0.002", which doesn't add up even to a 1% transaction fee in the worst case scenario.

when will my hosted miners with gawminers be able to work at nicehash? since they use cgminer

[greatwolf]

What's going on with nicehash server? My cudaminer keeps crashing.
