I have heard that one bad thing with storj is that it does heavily use your internet Connection to do performance tests on the storage system. Also users uploading and downloading files taxes your Connection. It might not be worth it if it makes your internet slow for other usage. Burst mining on the other hand is light usage on internet because it does not transfer much data on the network.

Now that Intense Coin is changing codebase to Monero it will be even better than Monero. The upcoming VPN feature will make it a coin with a real purpose, not just any other random coin. You can also be a VPN exit node to earn Intense coins by renting you own internet connection to VPN users.
103  Alternate cryptocurrencies / Mining (Altcoins) / Re: AMD Opteron 6378 4x, total 64 cores hash? on: January 25, 2018, 02:54:07 PM
I have 4x Opteron 6276. The best hashrate I got was 2030 H/s using xmrig with 56 threads and set affinity to 0xFEFEFEFEFEFEFEFE.
But my server overheats after a while with that setting so I had to change to 32 threads and affinity 0x5555555555555555.
Then I got a stable hashrate of 1700 H/s. That is the best long term stable hashrate I have got.

You can check http://monerobenchmarks.info/
4X AMD OPTERON 6282 SE 1801 H/s -a crytonight -t 64

I actually got higer hashrate running 56 threads than with 64.
But my Power consumption is around 600W so I guess it is better using AMD Vega GPU which can give same hashrate but at much lower power.
Opteron 6300 series should use a Little bit lower Power but the performance should be similar as 6200 series.

I just completed a server rig build with two motherboards. One with 4x 6276 and the other 4x 6376. I was hoping you might be able to answer a few questions.

1) Are you running Linux or Windows Server?

2) I tried the affinity settings you used for xmrig but only manage 140h/s. Do you mind sharing your full config file with me?

Any pointers or thoughts on your own troubleshooting to get the fastest hashrate is greatly appreciated.

Cheers!  Cheesy

Hi!

1) I am using Arch Linux because that is my favourite OS. Have not tried Windows but there might be an issue with maximum number of CPU sockets allowed by license. Linux does not have that kind of limitations.

2) I also have filled 16 memory slots to give each CPU node dual channel memory (each CPU consist of two 8 core CPU nodes with two connected memory channels). Could it be an issue with memory speed? It was a while I mined cryptonight but I can check if I have the config on disk when I am back at home. The affinity setting is to lock the threads to specific CPU cores. I did initial testing on my 8 core AMD FX-8350 in Another computer which is similar to one of the CPU nodes of the server. Just scale up the settings to all CPU nodes on the server. Not sure if I used "low Power mode" when running at 32 threads though. As I said, I'll check my config.

I also have compiled xmrig myself in order to get all CPU optimizations that might be needed on my system. Don't Think it matters much but if for instance AVX is not used it would affect the results.

But I had big issues with server restarting when overheating something. It was not an easy build, lot of tweaking needed both hardware and software to get it run stable. If doing it again I would probably go for a dual socket version and maybe getting two servers instead of one. Also check Intel Xeon servers.

It is a great machine to use when you find some "CPU only" coins. Initially I was going to use it for Verium mining (should be one of the fastest builds for that) but have not yet tried Verium mining. Have been mining Intense Coin and Credits but now difficulty is too high. I am trying Yenten but does not seem very profitable. Not sure what to use it for right now. But it has already paid for itself so I just use it for fun now. Maybe will try Verium. Forgot that it was the intended purpose :-)

Edit:
./xmrig -a cryptonight -t 32 --cpu-affinity 0x5555555555555555 --av=1 -o itns.intensepool.net:5555 -u ADDRESS.30000 -p x

or

./xmrig -a cryptonight -t 56 --cpu-affinity 0xFEFEFEFEFEFEFEFE --av=1 -o itns.intensepool.net:5555 -u ADDRESS.30000 -p x

Note: This was made using an earlier version of xmrig intended for CPU mining only. I beleive later versions integrated GPU mining also. The pool I used does not exist anymore so don't try mining there.

Which are the coins you know?

I only know burst. I stopped mining burst a couple of months ago because not profitable but I Think it might have been profitable again.

There is Siacoin and Storj but that is not mining, it is more renting storage space with payment in crypto.

Jag fattar fortfarande inte hur jag ska göra om jag minat och hållit på kryptovalutan så att den gått upp i kurs. Sedan så småningom säljer jag den till bitcoin som jag växlar till SEK. Då är det bara eventuell värdeökning på bitcoin som är inkomst av kapital? Resten inkomst av tjänst? Hur gör jag om jag bara sålt en del av det jag minat och behåller resten för framtiden? Jag ska väl inte skatta innan jag fått några pengar i handen?

Jag tänker att det kan vara en fördel att få upp inkomst av tjänst om jag kan kvitta det mot utgifter som el och inköp av hårdvara. Det kan vara en nackdel att få för hög inkomst av tjänst om det blir marginalskatt. Det som är gjort är ju gjort men det är bra att veta hur man ska göra i framtiden. Direkt växla mininginkomster till något annat eller hålla på dem.

Jag har inte kvar några historiska data på vad kursen var då miningen råkade betalas ut. Tänkte att inkomsten blir ju inte förrän jag säljer. Som exempel har jag minat CRDS Credits och den handlades på Coinsmarkets.com som numera ligger nere. Det var inte noterat på coinmarketcap så jag kan inte läsa ut kursen där. Men det går ju att frå fram utbetalningstillfällen via mina wallets men det blir tusentals transaktioner.

Det är helt orimligt att kunna göra rätt. Reglerna är oklara och i praktiken omöjligt att få fram allt som behövs i efterhand.
Men man kanske skulle ge dem en deklaration på hundratals sidor så de inser det orimliga i det hela...

Aktier kan väl också ha gått upp hundratals procent? Trodde samma regler gällde för all kapitalvinst. Fasen vad de ska krångla till det!

Antar det som står för bitcoin även gäller altcoins?

As a complement I think a decentralized Exchange would make it easier to buy ITNS in countries where crypto trading on normal Exchanges is blocked. If you want to anonymously buy VPN you first may want to anonymously buy intense coins. You can mine some with your CPU to get VPN access to be able to buy more. I quess there will be decentralized ways to exchange fiat to crypto.

Kan man inte köra schablonmetoden då när man beräknar anskaffningsvärdet?
Man sätter 20% av försäljningsvärdet som anskaffningsvärde.
Har man gått med mer än 400% i vinst så tjänar man ändå på att göra så.

Genomsnittsmetoden
Om du vet vad du betalat för dina aktier så kan du använda genomsnittsmetoden. Det innebär att du slår ihop samtliga anskaffningsutgifter från varje inköpstillfälle som skett innan försäljningen. Dividera sedan denna summa med antalet aktier som du hade innan försäljningen. Det framräknade beloppet är det genomsnittliga anskaffningsvärdet (GAV) per aktie. Detta belopp använder du som omkostnadsbelopp i deklarationen.

Schablonmetoden
Om du inte vet vad du betalat för aktierna som sålts så rekommenderas schablonmetoden. Denna metod är vanligt förekommande om man fått aktier i arv eller gåva och varken du eller banken har kvar uppgifter om anskaffningsvärde. Schablonmetoden innebär att 20 % av försäljningsvärdet anges som anskaffningsvärde. Denna metod är också mer fördelaktig om dina aktier stigit mer än 400 % eftersom din deklarerade vinst och därmed skatt blir lägre än med genomsnittsmetoden.

Källa: https://blogg.avanza.se/avanza/tips-infor-deklarationen-2016/

För egen del känns det ännu jobbigare då jag inte bara gjort trading utan också mining. Vid mining får man ju kanske 50 utbetalningar om dagen från sin miningpool. Går ju inte att uppskatta värdet på dessa. Särskilt inte om man minat kryptovalutor som vid miningtillfället inte var listade på någon Exchange och alltså då saknade värde. Blir det 0 i anskaffningsvärde då? Samtidigt har man lagt pengar på el och hårdvara. Sedan har man hållit på kryptovalutan och den har stigit i värde så en del av det är ju kapitalvinst och en annan del tror jag räknas som inkomst från hobbyverksamhet. Tänker om jag kör schablonmetoden och sätter 20% av försäljningsvärdet som anskaffningsvärde så är dessa 20% inkomst av tjänst (mining) och resten kapitalvinst?

Hi ! Can somebody explain this : I get better hashrate on i5-4460 than i5-4690 and this is happening only on cryptonight; and can't be a technical issue because I have tried on other coins ( not cryptonight ) and there, things are going logical , 4690 of course better hasrate than 4460. Thank you for the answers !

How many threads are running the miner on?
For cryptonight each thread requires 2MB of CPU cache memory for optimal speed.
So both your CPU should get best results using 3 threads becuase they have both 6MB cache.
I also recommend using xmrig miner.

How is hte cooling? If the CPU runs too hot it might start to downthrottle the Clock frequency.
Maybe the slower CPU is cooled enough because it runs at lower Clock frequency and then it does not throttle because of heat.
But the faster CPU might get too hot and start throttling.
109  Alternate cryptocurrencies / Mining (Altcoins) / Re: How to estimate Mining Results? on: January 23, 2018, 08:10:21 PM
Main reason to not switch too often is that difficulty varies a lot so you might just hit an unlucky period. Another reason is that pools use PPLNS and similar systems that makes pool hopping unprofitable. The mining pools are rewarding the miners that stays longer on a pool.

leonix007, ronnylov

Thanks a lot for your answers. It clarifies a lot!

I'm very new in the crypto world, and I started mining well-established coins. But I'm starting to check on new developments, like Cerberus, GIRO and other new coins that seems very promising.
So It was crucial to me to get an idea of my possible mining results.

Thanks again!

Yes this is the way to do it! If you follow whattomine.com top results all other people do that also. You get average profit by doing so. To get better than average mining profit you have to find profitable coins that most other people don't know about yet.

I use to browse mining pools and check what coins they have. These coins are minable.
Then I choose between the lesser known coins and do the calculations. Sometimes I found a nice one and mine it for a while.
For instance I found PlusOneCoin a few weeks ago. Very nice profit for one week until some big miner found it too so I had to stop.
Mostly this calculation method gives a good estimation of profit even Before I start mining.
Real profit is often a bit lower than calculated but still you can find some good coins this way.

But best thing is too not change coins too often. Give each one at least one week of mining Before switching. If good then stay for longer.
111  Alternate cryptocurrencies / Mining (Altcoins) / Re: Been mining for a month and.. on: January 23, 2018, 03:40:56 PM
I have Another story. Started mining 7 months ago. Yes ethereum was a Disappointment at the time but still I mined 0,5 ETH in a month with my GTX 1060. (What is 0,5 ETH Worth today if I had not sold it). Anyway I got some more Equipment and found Intense coin. It looked like an interesting Project but it was not on any Exchange. I thought maybe difficulty is low because of early stage? Bought an old server with quad CPU and some more second hand GPU and mined at all computers I had.

Some months later I had 330000 ITNS. I sold 80000 to pay off all my mining stuff I had bought and 250000 ITNS is pure profit. Even if it felt bad when price was below 10 sat it is better now when price is around 300 sat. My profit is around $8000 if I sell them today. I am holding them longer and hoping for much better profit in future.

So instead of looking at current profit you can try find a promising coin for the future and mine that. Hold the coins you get and sell them in future and you may gain a high profit. This is called speculative mining and is somewhat risky. But also fun!

I experienced exactly your problem when I bought my first mining GPU back then. Calculators said ROI of 2 months. But price of ETH fell down quickly and difficulty of mining was really high, calculators said 12 months or more ROI two months later. But afterwards I have found out that it is in these boring periods you actually earn most when mining. Nobody Thinks you earn much with mining and difficulty is low because the price of coins is low. You get a lot of coins but they are not Worth much if you sell them directly. Hold the coins until next price spike and sell them with nice profit!

So don't look at mining calculators. Or maybe do what calculators say you should not do. When Everything turns around you have already got your coins and you sell them. It is like stock markets. Buy low and sell high. Do the same when mining. Mine your coin when other people mine something else and get profit later.
112  Alternate cryptocurrencies / Mining (Altcoins) / Re: How to estimate Mining Results? on: January 23, 2018, 02:53:47 PM
I use google and searc for "ANN Sparks" and get the link to the coin announcement:
https://bitcointalk.org/index.php?topic=2634042.0

Here is info about coin:
Sparks Coin Specs

Symbol: SPK
Algo: Neoscrypt
Block time: 120 Seconds
Difficulty adjustment: each block (Dark Gravity Wave)
Block Reward: 18 per block
Masternode Reward: 50% Block reward
Mining Reward: 50% Block reward
Darksend: Yes, TX obfuscation
InstantX: Yes
RPC port: 8890
P2P port: 8893
Max Supply: 36,800,000
Premine: 650.000*
**Premine is for things such as listings and dev fees

So now you know that it is Neoscrypt, 120 seconds/block and miners get 50% of 18 Sparks per block. So all miners get 9 sparks on every block. 120 seconds per block means 30 blocks per hour which means 720 blocks per day. Total rewards to miners is 9*720=6480 Sparks/day.

Then you can check total network hashrate with a block Explorer. It say it is around 16.2 GH/s right now
http://explorer.sparks.gold/

So that means in order to get 6480 Sparks/day you need to own the total network hashrate of 16.2 GH/s.
Now you need to check your own mining hashrate. I understand that you have 4 MH/s
Nethash (according to block Explorer): 16.2 GH/s = 16200 MH/s

Your part of total nethash is 4/16200.
So one day you get your part of total mining reward:
6480 * 4/16200 = 1.6 SPK/day

With your example nethash is 18.2 GH/s would give 1.42 SPK / 24 h

This is a rough approximation.


Another way is checking what the mining pool say.
Altminer.net say reward 9SPK, pool hash rate 819.3 MH/s and TTF=42 min (right now when I check).
So with 819 MH/s you win one block reward of 9 SPK each 42 minutes.
Your part of pool hashrate is 4/819. So your TTF is 819/4 * 42 minutes = 8600 minutes
You need 8600 minutes to get 9 SPK on the pool. 8600/(24*60) Days = 5.97 Days

So you get 9/5.97 SPKS per day which is 1.5 SPK/day
But you have a pool fee of 0.9% but that is so small that you don't have to take into account in this rough estimation.

The values change all the time but a rough estimation is 1.5 SPK/day.
1 SPK = $14.87 so that would make it $22.3 / 24 h.
113  Alternate cryptocurrencies / Mining (Altcoins) / Re: AMD Opteron 6378 4x, total 64 cores hash? on: January 22, 2018, 08:31:14 AM
Okay yah I'm in... Ordered 9x systems with 4x Opteron 6380s per system.

Suggestions on the best / easiest way to install Linux on these ?


You install Linux just as on any other other computer, no difference.
I have a 4x Opteron 6276 server and had some trouble getting it stable because of heat.
Had to replace heat sinks and underclock a bit to make it run stable.

Keep in mind they are power hungry. 600 W per system is my guess.
Also very high sound level because of the cooling needed.
Still it is a good CPU miner for CPU-friendly algos.

Edit: And as I said above the Opteron 6200 series is almost as good as 6300 series opteron.
The 6300 series was much more expensive when I bought mine.
114  Alternate cryptocurrencies / Mining (Altcoins) / Re: Best CPU Mineable Coins in 2018 and CPU Mining Guides on: January 19, 2018, 07:20:16 AM
why focus on cpu mineable coins?  99.99% of those coins can be mined by GPU.

You mine CPU-optimized coins on CPU and GPU optimized coins on GPU and you get better combined profit.
Some have very strong CPU, like multi socket  servers that idle most of the time. They can mine with CPU and get power bill payed and maybe some profit also.

If the price continue to rise I dont mind the "ROI decrease". I mean I bought my MN for something like $600 so my ROI now is like 1400%. Wish I had bought more than one but I could not afford more and still can´t. Well if I save the MN rewards I can buy another one in a year. I really like my Monoeci masternode.

Holy smokes XMCC keeps going higher and higher, what's the news guys.  I don't mind the profits but I'm wondering about economic application and payments with XMCC. 

New website today is the latest news. Not sure that is the reason for higher prices but I like the new website.

Yeap! Waiting for news and lookitg at the price!))
Hope it will raises greatly!

I hope it will not raise Smiley or nothing we can do with maining Smiley just do it slowly

Already a great Network hashrate. Mining turns into room heating. If price raises greatly, it will be easier to speculate. And do not mine.

Maybe not. Higher price and higher difficulty might even out so it still is profitable. You get less coins but each coin is worth more. Look at ethereum, a lot of people still mine with profit.
