If anybody is interested: you can sell & buy whirpoolX hashrate at NiceHash.com to mine VanillaCoin.

For those interested in selling hashing power on NiceHash/WestHash: WhirpoolX algorithm has been added

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

Update: cgminer extranonce.subscribe extension is now included in AntMiner S5 and Spondoolies SP20 and SP3x firmware, so all you have to do is update your firmware and add #xnsub at the tail of stratum connection string. If anybody is interested, our test Avalon4.1 is also running fine on NiceHash.com. Here is compiled binary for Linux 64 bit (includes extranonce.subscribe, compiled from our official cgminer fork) : https://www.nicehash.com/download/cgminer-Avalon4-Linux64.zip

If you are using Ubuntu you can simply connect your Avalon4.1 and run cgminer from the above zip file:

sudo ./cgminer -o stratum+tcp://stratum.nicehash.com:3334 -u yourBitcoinAddress -p x --avalon4-automatic-voltage --avalon4-fan 40

(--avalon4-fan is percentage of fan speed)

If you wan't to build cgminer from source just use the source from our official cgminer fork.

Here is a screenshot of under-clocked ("avalon4-voltage" : "7000", "avalon4-freq" : "320:310:300") Avalon4.1 running on NiceHash.com:

Migration to new multi-sig Bitcoin deposit addresses has been successfully completed. Just press "Generate Bitcoin deposit address" at your Account / Wallet and you'll get your new Bitcoin deposit address and fully functional multi-sig NiceHash Bitcoin deposit wallet with full previous history. And please remember - do NOT deposit to your old address (but in case you did it by mistake, further instructions to recover those Bitcoins was sent to your account's email address).

Thank you for using our service!

Dear customers,

We are very pleased to inform you that NiceHash is upgrading to enterprise-level multi-signature wallets. For this purpose we have integrated BitGo's multi-sig technology. NiceHash is now joining leading services to incorporate the industry's best security practices available today.

Switching to a new platform requires changing deposit addresses. The switch will be done on February 25th at 15:00 UTC. Our web site will be put into maintenance mode on February 25th for approximate 1 hour during 15:00 UTC and 16:00 UTC. Stratum servers will be running unaffected, therefore your orders will also be running as usual and mining will be unaffected. Of course no coins or funds will be lost, just transferred to new deposit addresses. When you'll log-in after the maintenance you'll have to manually click "Generate Bitcoin deposit address" and your existing funds will be instantly credited to your new deposit address.

Please keep in mind that after February 25th at 15:00 UTC you should NOT deposit Bitcoins to your current deposit addresses, but instead use newly generated one (once it will be available after the switch).

We would like to thank you for using our service. We will continue to improve our service, make sure it's reliable and secure as well as introduce new features in the future upgrades.

Current direct Bitcoin mining profitability is 0.0107 BTC/TH/day, and current profitability at NiceHash is a few percents above this, so you should set your p lower.

ref: http://www.coinwarz.com/calculators/bitcoin-mining-calculator (set "Hash Rate (GH/s)": 1000, leave everything else at defaults)

Nobody from Betarigs contacted us so far regarding this matter. BetaRigs is having major issues since the acquisition from new owner, however there are no issues at our side. I suggest you to sell your hashing power directly via NiceHash/WestHash.

ckolivas, we respect you as a cgminer developer and overall contributor to Bitcoin community and we are not looking for any scapegoats here ... we're just trying to run a service where both - owners of the mining devices and those who are seeking for hashing power to rent - can benefit. We'll continue to work with hardware and software providers to make sure that various crypto coins (not all of them are shitcoins) will be mineable by various mining devices.

Sorry, we've given you the wrong port, it's 3334 for SHA (3333 is for Scrypt), that would be:

stratum+tcp://stratum.nicehash.com:3334/#xnsub#skipcbcheck
or
stratum+tcp://stratum.westhash.com:3334/#xnsub#skipcbcheck

Buyers of hashing power at NiceHash/WestHash are not only mining Bitcoin, they are also (sometimes) mining various other coins. Some of them are still at very low difficulty, switching jobs very fast, etc. Unfortunately manufacturers of ASIC miners are putting very weak controllers in their miners (saving a few $ in a machine, worth hundreds even thousands of $ ) with non-optimized software and are thus unable to process large number of shares/jobs/work-restarts. A typical example was KnC Titan (not SHA256, but an Scrypt miner) which was only able to mine Litecoins until the controller software was properly optimized. Recent example of a SHA256 miner that is having a few issues with rejects is AntMiner S5, hopefully Bitmain will improve it soon. If manufacturers would put a multi-core Raspberry Pie 2 in their miners (with a good controller software - I'm not talking only about cgminer/bfgminer, but also drivers, etc. handling of low difficulty coins, switching jobs very fast, proper handling of flushwork, etc.) there would be no issues. For example, there are no issues with sgminer mining any GPU based coin, running on PC (which always has a decent CPU). Probably there is also room for improvement in cgminer itself for these issues.

Anyway, we are aware of these issues and we've implemented measures to mitigate these issues a long time ago. We are rewarding providers (sellers) with extra shares paid by buyers when fast work restarts happens. If you are a seller it is very important for you to monitor the average mid-term hashrate, reported on our website (it is calculated from shares, rewarded to your miner) and the actual earnings, not only the hashrate or accept/reject ratio that is displayed by your miner hardware/software, since in some cases you will be rewarded for more then your miner is showing you in terms of hashrate. Details are explained in this FAQ.

Please send us your bitcoin address, used for mining with this miner on NiceHash and possibly also your public ip address to support@nicehash.com so that we can check what could be the issue for this.

Multi-algo ports are specific. It is possible that someone places an fixed order for 50%, then many miners switches to other algorithm and there is no more hashing power available (and we can't "take away" the already assigned hashing power from fixed orders).

We fixed this so that we implemented lower fixed orders quotas for low hashing power algorithms.

Current quotas are:
 { 0.5, 0.5, 0.1, 0.4, 0.2, 0.1, 0.2, 0.1, 0.2, 0.2 }; (0.5 means 50% and so on)

Where algorithms are
 { sha, scrypt, scrypt-n, x11, x13, keccak, x15, nist5, neoscrypt, lyra2re };

We will monitor the situation and tune our system accordingly.

Thank you for using our service!

Please take a look here: https://www.nicehash.com/index.jsp?p=software#bfgminer

1. Update your miner to the latest firmware.

2. Set pool like this:
stratum+tcp://stratum.nicehash.com:3333/#xnsub#skipcbcheck
or
stratum+tcp://stratum.westhash.com:3333/#xnsub#skipcbcheck

Again there are currently some very well paying orders. Past 7 days average price is also good: +5% more then direct Bitcoin mining. You are welcome to join our service.

This should not happen. Are all miners at the same location, same public IP? Are you 100% sure you're using VALID bitcoin address as username? Are 100% sure you using exactly the same password factors (try copy paste to make sure).

Hi,

Today we introduced an attractive feature for buyers of hashing power - fixed orders.

This type of order will allow you to place an order with fixed price and will guarantee you the the desired hashing speed through order's lifetime, even if there are other bidding orders with higher price submitted later on. You will have to pay a bit higher price in relation to current fixed orders demand. This type of order is especially appropriate for renters of smaller amount of hashing power who are seeking for a way to rent hashing power with a peace of mind with no need to watch over the order in case some other to over bid you. This is essentially the same as renting a physical miner or renting a physical rig, however you still retain all the benefits of renting hashing power by being able to cancel the order any time and pay only for accepted shares without any risk for faulty configured rigs. Needles to say that this type of renting is also prone to bots manipulation since the hashing power is dedicated to your order.

Please take a look at updated FAQ "How can I buy hash power at NiceHash?" for all the details.

So, if you're still in the old-school of directly renting rigs now is the time to upgrade to our Fixed orders - in most cases you will get a price well below directly renting miners or rigs while still preserving all the benefits of renting hashing power with the same careless experience as having your own on-demand miner or rig!

Thank you for using our service.

We have ping disabled on our stratum servers, but you can ping the endpoints of our provider's datacenters:

"ping speedtest.ams01.softlayer.com" for NiceHash
"ping speedtest.sea01.softlayer.com" for WestHash

this will give you ping results, use the one that gives you lower ping results (lower ms).

Hi, BITMAIN,

We noted that AntMiner S5's are having some minor issues when mining some particular low-diff and fast-work restart coins. Users which are mining on our NiceHash/WestHash SHA256 pool are seeing up to 5% rejects in particular periods of time when these miners are working on low-diff and fast-work restart altcoin orders. Could you let your technicians to look into this and provide some patch in the future firmware? Could this be due to too weak controller not being able to process all shares when working on low-diff and fast-work coins?

Kind regards,
NiceHash
