I've just compared switched my small farm (5 Gh/s Eth) to Nicehash and I'm not happy at all. While the idea of just mining the most profitable algo is compelling, there are a few challenges:
* It doesn't use the best/most efficient miner (often you get better rates with modded miners targeted to your HW)
* OC settings are incredibly hard for multi-algo, wich means you need to go subtle / generalized OC and loose a couple Mh/s there too
* Fees are too high (its just too high)
I switched back to Signatum mining using ccminer for now, still exploring better mining options.
Buying coins is a safe choice and the most passive option so you don't invest your time. If you put a number behind that its the most profitable I assume. While I'm in for the long game and its exciting to figure out new stuff I would have been better of investing the money just into BTC or ETH.
You can use claymore or any other miner to mine at nicehash.
I've always assumed that the "accepted hashrate" chart is wrong, cause it is ALWAYS lower than the actual hashrate my rigs are producing.
I got 500 Mh/s ETH, at nicehash its currently showing 350 Mh/s as accepted speed. Does that actually mean it doesnt accept the the full "speed" I'm producing?
I got 0% rejected speed.
Am I losing profits?
Your miner is basing its hash-rate figures on how much work it is doing. Even though it is performing the hashing function it may not be generating acceptable shares at the rate the pool uses to estimate how much hashrate x number of shares over a certain timeframe equates to.
Pools such as Nicehash can only use how many valid shares they receive from your miners as a metric and then use that figure along with time to display a guesstimate of your hash-rate. Luck, latency, pool issues, developer fee shares, or even subtle miner hardware fluctuations can all contribute to a large difference between submitted and accepted share-rates at the pool compared to what you miner is displaying.
As far as are you losing profits, in almost all cases mining at Nicehash will result in less profits than mining a coin directly and then trading it yourself. Consider Nicehash charges buyers 3% to "rent" your hashrate. They also charge you 3% for the privilege of renting it out to the buyers. Also consider the people buying or renting this hash-rate need to overcome this spread in order to profit on whatever coin they are after, so assuming they aren't losing money this needs ot be an additional 2-3% or more profit to make it worthwhile. So adding all this up, as a seller you need to overcome from 6-10% of fees to make what you could just by mining whatever profitable coin people are willing to pay Nicehash to mine for them.
Thanks for reply!
Regarding "Luck and pool issues", shouldnt this be the renters problem?
Example from one of my rigs:
"ETH - Total Speed: 142.758 Mh/s, Total Shares: 1397, Rejected: 3, Time: 07:37
ETH: GPU0 28.547 Mh/s, GPU1 28.568 Mh/s, GPU2 28.560 Mh/s, GPU3 28.558 Mh/s, GPU4 28.526 Mh/s"
These stats kinda freak me out!
The average seems to be acceptable tho:
I do have 2 GPUs not listed in the screenshots above. (Old rig with cards failing 1 by 1, only 2 left
)
