I would like to second the vote on setting up some sort of payment threshold. Some of us are pretty small time players and it would be nice to have the option of selecting when I wish to cash out.
*BTW, did anybody else notice a hiccup in the sha256 pool this afternoon or is just me?

Information for buyers: Due to increased transaction dust, produced from mining directly into NiceHash deposit address, we can not allow this anymore. Many small incoming transactions are increasing online wallet load and also increasing outgoing transaction fees. We ask you to mine into your personal wallet and then transfer funds in your NiceHash online deposit address - it will be faster (we only require 2 confirmations) and cheaper in the end of the day. Unfortunately we will have to disable mining directly into NiceHash deposit address at the beginning of the next week. Many online exchanges and similar services have implemented this kind of restrictions in the past. Thanks for understanding and thanks for using NiceHash!
Another feature worth considering, payment threshold. Possibly as another password parameter such as "t=0.02" to transfer when balance reaches 0.02 BTC. If multiple values come in then take the lowest value recorded since the last payment. This could cause troubles, because someone else could use your BTC address and set ridiculous values for payment threshold. The only way to give this option to providers is to force them to register and that is not what we have in plans to do ever.

The only way to give this option to providers is to force them to register and that is not what we have in plans to do ever. Are you saying ridiculous in terms of how high or how low the threshold could be set to? High is not an issue as you would use the lowest value received. Low would still be constrained by the existing threshold you have set for per cycle and per day payouts. The worst a bad agent could do is cause the payment to go out before someone wanted it. That would put the provider back to the same payout schedule they have now which I don't see as a major threat. Regarding accounts, there is an alternative method for controlling settings in a confirmed way. Look at how the simplevert.com pool works. Stored settings such as payout addresses for merged mined coins is controlled using signed messages from the BTC address used. This way only the person who controls that address can change settings yet there is still not a need for collecting user information.

Forgive me if I repeat some things here, but I am new to NiceHash concept and I try to figure out exactly what are the benefits of this service.
I've been reading all FAQs but still one crucial thing remains vague: how much am I going to profit from investing X amount of BTC as buyer?
So let me add some clarifications here to "How can I buy hash power" plus "How much to expect" FAQ and ask from the community to correct where I'm wrong.
Comparison with CEX concept:
In CEX I am buying an asset (GHs) at price A which I hold for 1 day. At the end of the day I have income from mining B and I can sell the asset at a price C. My profit (income) or loss from that day is B+C-A. My risk here is that at the end of the day I may sell at price C lower than A, with the difference C-A being bigger than the mining income B, producing a net loss.
Comparison with Mining Contracts concept:
When buying a mining contract I pay for a specific hash power valued A BTC for a LONG period (usually 1 year). At the end of the year I can be 100% certain that I have lost A BTC. The seller is paying me C bitcoins on a regular basis. Unfortunately, due to the highly volatile crypto conditions, I run the risk that C payments X 1 year may not be enough to cover my initial investment A.
How can I compute the profit and risk from buying hash power at NiceHash?
At NiceHash I'm renting hash power A for a time period B (let's say 1 day) from a hash power owner (Seller). NiceHash acts as an intermediary between me (Buyer) and Seller, charging a 2% commission on each leg of the transaction. QUESTION 1: I do NOT own the hash power, this remains the asset of the Seller to whom it automatically returns at the end of time period B. Correct?
I am responsible to direct this hash power A to a pool of my chosing, lets name it POOL. POOL must obey certain technical specs (operate with my chosen algo (Scrypt, X11 etc) and be compatible with NiceHash stratum tech.
I declare a BTC wallet to NiceHash (separate from my deposit wallet) and NiceHash pays into that in bitcoins the value produced by the POOL. Let's call this value C. QUESTION 2: POOL may be a Litecoin, Dark coin, Noble coin, any coin pool. NiceHash is performing the POOLCOIN -> BTC exchange automatically? If so, isn't the actual coin selection (and not the algorithm) crucial to profitability? I mean, if I use the hash power to mine Litecoin will I get the same results as when mining Noble coin?
If all the above is correct, at the end of the day B I have lost the rent of hash power A and I have gained the value produced by my pool, C.
So with NiceHash my profit (loss) is C-A within a period B. The NICE thing with NiceHash is that period B can be short enough (hours - days) to allow me to calculate risks with a much more tight error margin than estimating returns of 1 year contracts.
Example: From NiceHash home page I read Statistics / Orders for Scrypt. I'm not sure if I read the info there correctly.
In the "Statistics" table, I read that Scrypt is currently paying 1.3463 BTC/GH/DAY In the "Orders" table, I read that order #26042 is paying 1.56 BTC/GH/DAY. QUESTION: Does this mean that buyer #26042 is paying 1.56 BTC rent to get 1.34 BTC - a guaranteed LOSS of 0.22 BTC?
The buyer in this case is just betting that his choice of POOL/COIN is so much in the rise this specific time period that it will bring him much more than the 0.22 BTC plus commission? The Seller, on the other hand, is getting paid upfront a price for his hash power no matter what the market conditions will be.
Finally, I fail to understand the meaning of "Remaining BTC" column.Remaining BTC of what? ETA hours is what?
I apologize for the lengthy post but this is the only way to clear out what I believe is the important staff here: how much is at risk and what can one expect from NiceHash as a buyer.

Yes. I declare a BTC wallet to NiceHash (separate from my deposit wallet) and NiceHash pays into that in bitcoins the value produced by the POOL. Let's call this value C. QUESTION 2: POOL may be a Litecoin, Dark coin, Noble coin, any coin pool. NiceHash is performing the POOLCOIN -> BTC exchange automatically? If so, isn't the actual coin selection (and not the algorithm) crucial to profitability? I mean, if I use the hash power to mine Litecoin will I get the same results as when mining Noble coin?
The only thing you can buy on NiceHash is hashpower. You manage your coins on target pool on your own. You decide when and where to exchange them. We don't exchange any coins. In the "Statistics" table, I read that Scrypt is currently paying 1.3463 BTC/GH/DAY In the "Orders" table, I read that order #26042 is paying 1.56 BTC/GH/DAY. QUESTION: Does this mean that buyer #26042 is paying 1.56 BTC rent to get 1.34 BTC - a guaranteed LOSS of 0.22 BTC?
Currently paying value is mainly for providers to consider (whether to put their rigs on NiceHash or no, according to current profit). Buyers should always check active orders, because "Currently paying" value does not give you much information about how much you should pay for the hashpower - "Currently paying" is only weighted average price. This means that you may get hashing power for price lower than that (usually if you don't need high speed) and if you want to buy all speed available, you will have to bid higher than "Currently paying". Keep in mind that orders are coming and going, that every customer can increase price of order, change speed limit of order and even cancel order at any time. Even one such action can shift price considerably in either direction. Basically, you are competing with other buyers where the goal is to get hashing speed for as low possible price as possible, but at the same time not staying without any hashing power. When deciding whether to rent hash power, all you have to do is calculate BTC/GH/Day (price Y) for mining certain coin with X hashpower. Then you buy X amount of hashpower for price <Y to make profit. The great benefit of NiceHash is that you are not limited to contract like with other rental services. If the coins profitability drop, you simply cancel the order and get remaining BTC back. Other rental services may render you negative profit, because you can't terminate renting contract. NiceHash is the rental service with minimum risk. Finally, I fail to understand the meaning of "Remaining BTC" column.Remaining BTC of what? ETA hours is what?
Remaining BTC is the amount of BTC still in order and that amount is given back to you in case you cancel the order. ETA is estimated time of completion of order (in hours) if the speed of your order remains unchanged until the end.

Thank you, nicehashdev, for the quick response.
It is now clear what I have already pointed out: the NICE thing here is that we can buy hash power without getting locked into a long term contract in such a volatile market. On top of that, we decide which coin to mine and handle the coins so mined independently of NiceHash.
To further clarify the "Remaining BTC" concept, I understand that when I place an order for, lets say 24 hours for 1 BTC, at 12 hours into the order I have consumed 0.5 BTC and I have 0.5 BTC not yet consumed so remaining (if I so decide) to cancel the order. So, the cost is not paid upfront but it is gradually consumed by the hour.
All in all, I believe this is a VERY competitive proposal when compared with long term contracts and it suits perfectly the highly dynamic nature of cryptos.

OK, i have some great news for those of us still using the older getwork type sha256 miners! but a brief explanation first, sorry. I have documented my miner issues in my earlier rantings in this thread about being kicked off nicehash ever since they implemented their DDoS protection measures, necessary of course, but it screwed my sha256 miner over big time. I thought it was nicehash's fault for awhile, but come to find out my miner had issues i wasn't really aware before that keep getting me banned. So I was willing to try anything to get my miner working, and so i followed the suggestion from Pfool about checking out his java proxy, and i am sure glad I did. Pfool obviously did all the work, but Pfool took my numerous debug logs and other network traffic to pinpoint my issues, which after only 5 days, Pfool identified and fixed it! Actually, as i am writing this, my miner is chugging along just fine, and it is great seeing an almost vertical line change show up in my sha256 payout chart on nicehash now. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) so here is what you need to do for your old getwork miners to get them working with nicehash again... 1. download the latest beta of the java proxy. it can be found here https://github.com/Stratehm/stratum-proxy/releases you have to have java loaded on your computer for it to run. the instructions to get it all running is on the main page of that site. 2. I have a ASICMiner Block Erupter Cube, which only uses getwork, hence the need for a stratum proxy. use the following command line with the java proxy to get it up and running. please note you need midstate enabled (default state with this proxy) for this particular miner. java -jar stratum-proxy.jar --getwork-listen-port xxxx -h stratum.nicehash.com:3334 -u YOUR BTC Address -p xxxx -n NiceHash --set-extranonce-subscribe true --validate-sha256-getowrk-shares changes the xxxx's to what you have going on for those options. Some final notes... my particular issue with getting banned by nicehash, was that my Cube was submitting shares that were either above or below the target difficulty, and while they were being reported as accepted by the proxy, they were getting rejected by nicehash. this basically looked like the reject share attacked they were DDoS with before, hence the instant ban. Now Pfool has implemented the "--validate-sha256-getowrk-shares" opion to have the proxy validate the shares before leaving to nicehash, and not submitting the ones that don't make the necessary targets. while this has resulted in drastic drop in the acceptance rate reported the Cube (not nicehash, i have nice blue lines ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ), at least it is not getting banned, and i am able to contribute some decent hash power again. i do want to stress that the latest version is basically a beta version, so i am sure Pfool will address this particular issue when he can, however it may be something that is inherent to getwork to statrum proxies that can't be fixed. i invite Pfool to chime in on anything presented here, especially if i am off base on something. i don't have a shred of programming skills, and my understanding of what is actually happening may be off. either way, my hat is off to Pfool on getting this far with my issue and i look forward to what he has in store for his java proxy. ![Cool](https://bitcointalk.org/Smileys/default/cool.gif)

Does nicehash has some limit like number of connections per ip or connection attempts per 15/30/60 minutes ? my 14 rigs having hard time connecting to nicehash, any port was using cgremote, most of the time it restart sgminer then can't connect to nicehash

Hi, your order #26868 has been listed under Scrypt orders. Obviously you've just canceled it and your funds have been returned into your NiceHash wallet.

Look at "Round accepted speed". Also "Round started" shows when the round started, so wait until a few hours have passed. I know this is not exactly what you're looking for but close.

Hi Nicehash dev, is there white list so I can avoid you ban me, I'm using slow internet but my rig so big (~600MB) that give me too many reject (~3% to 7%)
My wallet add is: 17BEAnCpVk88wg8Eszmbw8periW1ZXv9BG (in case u can add me in your white list).
Thank you.
Why all the sudden did 70% of my miners fail over to my backup pool??? Is NiceHash having issues or what? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) it was working fine until 10 min ago? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) ?? No I and not using the P option.. I am also getting disconnects Are the connection problems ever going to get fixed? Like right now only half of my farm is connecting.

Nicehash dev, can you please look at our provider disconnect problem and fix it or all you care is buyer only? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) I didn't see you reply any of us about this disconnect problem, its really annoying when rig doesn't connect to NH and I have to reset modem to get new IP for NH accept me reconnect. Thank you.
