[ANN] NiceHash.com - sell & buy hash rate cloud mining service / multipool

[kenshirothefist]

I cancelled order #19987 ~15 minutes ago. Unspent BTC was not returned, although the fee was. Can someone from nicehash please look into it?

Please send me your account name and order # to PM.

First there has only been Bitcoin - almost no work for miner - run and forget, then came Litecoin - more tuning for Scrypt needed; then came X-altcoins - lots of work for miner to keep up with different coin profitability - solved by multipools; and now there are X-algorithms - lots of work for miner to keep up with different algorithm profitability - to be solved by multi-algo-auto-switching. Said that - if you like to constantly watch algorithm profitability, then you can switch miners manually, but if you just want to run your miners and let them get best profit four you - well then you'll have to go with multi-algo-auto-switching.

Today we introduced another advanced feature for GPU miners - Fine tuning with custom speed factors and daily costs. You can now set custom hashing rate factors and even your electricity power consumption as well! This will make sure your miner mines on absolutely most profitable algorithm. You can also configure your miner, for example, to only switch between X11 and X13 (whichever is more profitable) even if globally some other algorithm is more profitable. Visit https://www.nicehash.com/multialgo/#finetuning and play around I'm sure this is one very nice tool for GPU users to play with!

Once again, exactly what I was looking for!  You guys have revolutionized the concept of TRUE cloud mining.  Went steps ahead with automatic profitable ALGORITHM switching.  And now custom hash rate factors!  Basing scrypt-n on a static factor against scrypt meant my miner could possibly switch to scrypt-n even though my card is just incapable to achieving the hash rate the pre-determined factor was based on.  Now, I can set the factor based on exactly what hash rate my card is REALLY capable of and the profitability switching is now based on MY GPU's true capability.  So awesome, you all.  Thank you again!

SHA Stratrum on the fritz?

stratums down??

[nicehashdev]

Maintenance. Was posted on twitter.

Cannot create order. Please try again in few minutes.

[nicehashdev]

We found out that since yesterday, our stratum servers are victim of specialized sort of DDOS attack that imitates behavior of rigs and targets CPU usage.

We have applied certain fixes and we will continue to do so to get rid of this attack.

We are very sorry for the inconveniences regarding orders. If your order was stuck, failed to be created or cancelled with no refund, please contact support at info@nicehash.com and we will take a look into it.

HI. I tried your version of sgminer to mine x11, but not working, HW, no accepted share.

I'm using the same .conf as the one i use with sph-sgminer_x11mod that work on all pool but have the idle bug here.

Anything wrong in conf or it's just the sgminer not working ?

		"pass" : "p=0.8"

Edit: in sgminer_v5 you can set algorithm in global section with "algorithm" parameter ("kernel" setting is irrelevant in sgminer_v5 and is actually calculated from "algorithm" setting, default "algorithm" is "scrypt" which by default points to ckolivas kernel)

Code:

{
"pools" : [
...	{
		"url" : "stratum+tcp://stratum.nicehash.com:3336",
		"user" : "btc-add",
		"pass" : "p=0.8"                
	},
...
"algorithm" : "darkcoin-mod"
}

You can also set algorithm per pool

Code:

{
"pools" : [
...	{
		"url" : "stratum+tcp://stratum.nicehash.com:3336",
		"user" : "btc-add",
		"pass" : "p=0.8",
                "pool-algorithm" : "darkcoin-mod"
	},
...
}

Soooo when is the next payout? cause there hasnt been one for almost 18 hours? if this is because of the DDOS attack then its all good. i was just curious when the next would occur.

There have been payouts: https://www.nicehash.com/index.jsp?p=miners&payments

Last two for all balances over 0.01 BTC and one before for all balances over 0.0001 BTC.

[nicehashdev]

You will be paid in 15 minutes. Next payment is for all balances > 0.001.

[Crypto84]

oh, ok thanks. i didnt know certain amounts were paid at certain times.

[odie158]

my orders which have been mining on btcguild are suddenly dead (low difficulty). They had been alive for days and BTCguild is usually rock solid did something change with nicehash?

[nicehashdev]

Stratum pool has to use extranonce2 size 3 or higher. Minimal pool difficulty is 16 (0.001 for X11 and X13).

We had to change this, because some pools were using difficulty 1 regardless of hashing speed being sent towards them causing very high load on our servers thus bad performance. Every decent pool gives you ability to configure worker difficulty, so make sure you configure higher diff (we recommend at least 4096 or more).

I had minimum difficulty set at 1024. I increased it to 4196. Still seems dead. What pool does nicehash think works best with its service? (don't say ghash.io)

Thx sgminer start and hash, but another trouble

Tried "algorithm" : "darkcoin-mod" or "algorithm" : "darkcoin" but speed is only between 1 to 1.3Mh/s on my R9 270 compared to the 2.02mh/s stable with the x11mod version.

Anyone have good settings for the r9 270 or can tell me if something else is wrong in my conf ?

You can see why the pool is dead if you check your orders page. You get status regarding all bridges.

Can't connect to the Scrypt-N port for the last 4 hours now. Front page stats are wonky too, shows non-zero hashrate with zero miners on some orders. Scrypt rig is mining to a backup pool, so I assume it has issues too. X11 seems to be ok. I wish you guys had some more status updates. Like the twitter DDOS message from 10h ago - not sure if that's still ongoing?
