Crypto currency mining is fascinating topic. It is 21st century mining with computer hardware and software. Looking for blocks on the block-chain to be rewarded in crypto currency. To start crypto currency mining business or hobby you have to understand what kind of risks you might face. To start Bitcoin mining you will need and ASIC miner, which is basically bunch of CPUs. This kind of equipment might cost you a lot of capital, so it is a good thing to recognize the risks you might face.

✔️In the early days in Bitcoin mining you could make some profit with your laptop CPU or GPU. These days are long gone, every year new more efficient hardware is been developed. Which makes older hardware obsolete for mining. Meaning that bad timing investment could potentially make your investment worthless.
✔️Hardware failure is very big thing to reduce mining risks. This hardware needs to be run 24/7 to gain the most optimal revenue from mining. Very often these devices/hardware do brake down, asic miners are the worse hardware comparing to GPU. Hashing board failure is common problem on them, which will need additional investment after 6 month from your purchase. If this would happen to your devices.
✔️The one of the hardest parts is not enough profits. Crypto currencies are extremely volatile, one day you could mine in profit the next day you might be at loss. If you are using latest hardware, most important to stay in the game and mine with profit. Is to have cheapest electric rate between all the other miners on network. Electric is everyone biggest OPEX cost, dont even think to start mining as a business large scale if your power costs is above 6-7c a kw/h. It might be profitable to mine with 20c per kw/h today but it might not be anymore tomorrow. Which means you will need to shutdown your mining farm.
✔️Legal risks . Crypto currency is still very new, and it has not been regulated very well. So you might face some kind of crypto currency ban in the country which might affect your mining operation.
✔️Hacking – Use crypto currency safe as possible. You know the good old saying not your keys not your coins. Don’t keep your mined coins on exchange. And use only community trusted mining pools.
✔️And the last of the top 6 is the environmental risk. Choose mining location wisely. Mining hardware most likely will use a lot of power, this is why they will produce a lot of heat. And heat will affect your mining operation. Something like mining container could be an option.
Recognize your risks before starting a mining operation.

We are back!

For the last 2 years there was not much to shill in mining mining was on the life support. And the profits constantly got decreasing. Start of 2020 Bitcoin and Altcoins are showing great performance in price action. This price action has also increased mining profits in some coins for more then 100% since december 2019. It might be to early to say that “we are back” , as crypto can be so unpredictable. But there is a lot of signs that we have now oversold a lot and value of crypto market is increasing steadily. We might see this pattern continue for good bit of times as BTC halving is coming up in 3 month. Let’s get in straight in. I will choose 3 hardware devices which in my opinion would be the best choice and we will see how profitable they are.

If you are new to mining and you want to know which devices to choose, choose from top market cap coins latest equipment. This will be your safest bet, as the mining profits are much more stable on bigger cap coins then on smaller cap coins. If you are small miner and don’t have large electric bills, you can choose smaller cap coins. They might go up in price lot faster then bigger cap coins in bull market, but be aware they they might dump lot faster. It is high risk high reward type of mining.

If you are really serious about mining, you need to look at cheapest power source possible which would be in 0.05c a kw/h range. It is not 2017 and mining from home wont be profitable at 0.30c a kw/h. Industrial power is possible to achieve 0.05 in many places in the world. If it is not possible in your country , look for the country where it is possible. So all profit calculations done for 0.05c a kw/h

Top mining profitability websites :

https://www.asicminervalue.com/ It is great website to see newest ASIC miners and their profitability. Usually the new upcoming mining machines gets listed here. So come and checkout this page every few days/weeks this page if you are serious about mining.


https://whattomine.com/ Is the best known for GPU/CPU mining profitability. You can choose what ever hardware to use and it will give you the best and most profitable coins to mine. It is very simple to use it. It does have Also asic miner profitability check, but for asics i do prefer asicminervalue,com


The top and 3 most profitable Crypto currencies to mine in February 2020 , for some people miner pick could be different. The prices changes if you are buying new/used , depending in which part of the world are you. This is my recommended , brand new purchase in Europe.

✔️ Bitcoin – Most suitable Antminer S17+ . It is one of the efficient Bitcoin miner currently publicly available, alternatives would be M20s miner and Avalon miner 1166. Antminer S17 efficiency is 73TH/s @ 3000watts . Current profitability after you have paid your electric bill is 7.82 usd in 24hours , with ROI achievable in 6-7month. It does seems great, but crypto doesn’t stand still. And has plenty of risks.

✔️ Ethereum – Best miner to use is RX5700 graphic cards mining rig. I know there is an ASIC miner available A10, but most of you who are in mining will agree with me, that it is complete junk. It is only slightly more efficient then RX5700 gpu rig in terms of price per hash and watt per hash . But it is 10x more riskier investment in mining rig then buying GPU mining rig. So the efficiency of 12xgpu RX5700 mining rig is 640 mh/s @ 1700watts. Current profitability after you have paid your electric bill is 7.62 usd in 24hours , with ROI achievable in about 20-22 month. Ethereum is one of the underdogs which could perform quite well in 2020 and might reduce your ROI much more faster.


✔️ DASH – Lately has been released most efficient DASH miner STU-U6. Asic miners are very risky investment, but sometimes they might be very profitable. The beauty of this miner is that it is quite new model and it is mining profitably DASH , even that DASH is still over 90%down from its all time highs. This miner performance is 420GH/s @2100 watts. Current profitability after you have paid your electric bill is 8.11 usd in 24hours , with ROI achievable in about 5-6 month.


 

These would be my to pick miners for start of 2020. There is big risks in any on these miners as no high reward investment is guaranteed anywhere. I’ll have more detailed explanation of the risks of each of these miners in my next post.

Any miner suggestion, what would be your best choice and why?

For years now there has been possibilities to increase Bitmain bitcoin miners “antminer” efficiency with custom firmware. It is understandable that Bitmain don’t want their customers to change overclock on their asic miners. OC changes could possibly kill or damage hardware in some cases when chip oc and voltages applied to much. Overclock could kill miner it self or power supply. This is one of the reasons why Bitmain lately locks down their miners firmware, they dont want customers to do any changes on them.

The factory settings are standard, whoever is mining for while now. Knows that from some chips you can get better efficiency, just because quality of every chip is not the same. Lately there is been released an upgrade firmware and manual for Antminer S17 from hiveOS. HiveOS is gpu and asic miner monitoring/remote control. They previous firmware for Antminer S9 and T9 has been very successful. We have done review on this firmware also, and the best feature what Bitmain original firmware does not have is auto-chip tuning. It works very well, basically it finds the most optimal chip oc and the voltages to reach best efficiency.


We have now also tested the new firmware for Antminer S17, it does perform much better then Bitmain original firmware.On Antminer S17 53TH/s version , air cooled miner we where able to reach 75TH/s @3300 watts. It worked very well and setup is straight forward. It is possible to reach even better performance up to 85 TH/s , but you will need immersion cooling. As with air cooled at 75 th/s our miner chip temperatures where close to 80c at room temperature 15c. Also be careful , Bitmani stock power supply Antminer S17 max power usage is 3500 watts.

hiveOS asic miner the installation guide :

Notes
And now let’s go back to the installation process. There is no universal manual, for S17 and S17 Pro there are 3 versions of stock firmware. Therefore, every particular case has its own manual on the custom firmware installation.

Please note, that all the manual steps which involve using BTCTOOLS can be done via ASIC’s web interface (BTCTOOLS is usually used for a large number of devices).

Preparation Stage (required for all the options):
1 .Download and unzip the following archive: http://download.hiveos.farm/asic/repo/fw/Antminer/s9k-s9se-st15-st17-installer.zip.



Scan the network using BTC_TOOLS and export the list to csv. From csv, copy the IP list and insert it in ips.ini. In case you don’t have a lot of devices, you can make this list manually. Or use bitmain ipreporter tool.
Go to config.ini and check login and password for the ASIC’s SSH or web interface. If the password for the web interface was changed, the same would be for SSH. Set up FARM_HASH to connect to Hive or API, if necessary.



Download the firmware file (it has to have “Hiveon” in its title): http://download.hiveos.farm/asic/s17/
For S17 and S17 Pro, we offer the same firmware file. However, there are two options: “signed” and “nosigned” firmware. The signed firmware can be updated ONLY to another signed Hiveon firmware via ASIC’s web interface or BTC_TOOLS. Third-party or official firmware can’t be installed in this way. However, you can use the rm -rf /etc/bitmain-pub.pemcommand — send it to your ASICs via the Hive web. It will temporarily delete the certificate, but you can reboot your ASIC to bring it back. After this, you will be able to move to any firmware via the firmware update menu (in the Hive web). It will be possible to choose the firmware from the list or to use the URL.

The signed firmware can be downloaded here: http://download.hiveos.farm/asic/s17/Antminer-S17-S17pro-Hiveon-1.00-sign.tar.gz


If the stock firmware of your ASIC is released before 1 July 2019
Flash your devices with a file from the archive “remsigallbefore_2019–07–01.tar.gz”. This can be done via either ASIC’s web interface or BTC_TOOLS in case you have a lot of devices. You will see an error in status, but this is okay — it should be like this at the moment.
Flash the devices with the firmware file. Again, this can be done via either ASIC’s web interface or BTC_TOOLS.
Launch “3hashfarmforsigned.cmd” from the archive. The ASIC will get connected to the web.
Stock firmware released from July 2019 to December 2019
Launch “1openssh.cmd” from the archive and wait for the script to be performed. The devices will be rebooted. After the reboot, wait for around 3 minutes.


Launch “2upgradereplace.cmd” from the archive and wait for the script to be performed.


Flash the devices with the firmware file (via either ASIC’s web interface or BTC_TOOLS)


Launch “3hashfarmforsigned.cmd” from the archive. The ASIC will get connected to the web.
 

Please be aware you could damage your hardware by applying new overclock to your Antminer S17 . Biggest downside of this is that there is 2.8% dev fee. I know quality product is never for free, but cheaper option would be better

Original post

We are not even in a bull market yet. Usually these things happen when there is a lot of hype. ZigmaBit is scammer company with fake mining rigs to basically scam you. Their selling website is https://zigmabit.com/ , please don't even click the link. We do not want to give them any traffic, just watch the video down below.

They have listed 3 miners on their website:

ZigBit 2.0
ZigBit 3.0
ZigBit 5.0

Which of course doesn't exist. They recommend that these miners will make some crazy gains, which of course will not happen. As these miners are fake. Seeing the specification makes me think these guys know very little about crypto currency mining. So for example the specification they are advertising on ZigBit 5.0 is :

Bitcoin-2000 TH/s
Litecoin-300 GH/s
Ethereum-75 GH/s
Dash-50 TH/s
Power Consumption-2400W
Power Socket 110V-240V

Now you understand what im talking about, seriously 2000 TH/s mining Bitcoin at 2400w (where the latest Antminer S17 is 72Th/s), or mining ETH and the profit is so big that it will cover the miner cost faster then month. And another thing, they using the same hardware to mine multiple currencies which every one of them needs different hardware. Worst thing is that people will loose money, and most likely some of them already did. People think they will get rich after buying this miner, which they will never receive. Their fake products look so bad, their cheapest version ZiBit 2.0 looks like an ATX power supply.

Few things to also note is :

They have support chat on their website. I did send them a message and got response after about 20 minutes. So they told me that they only accept crypto currency, and the products are shipped from United Kingdom. My last line of the chat was "im coming for you you'll be in jail soon ".
When you google miner name, there is few websites coming up describing how great is their product. This most likely is owned websites for this scammer or this is purchased content posts.
Last thing is that i tired to do checkout on one miner, there is btc address which has already received 7btc. Im not sure if this is some people got already scammed or this is fake volume, hope this is fake volume https://www.blockchain.com/btc/address/1C4RSshoK9veR4jCNStqF32QARS5oGnmzw . Hope none is scammed.

Sad to see that there is such kind of people who makes money on scamming others. Man karma is there , i believe it will come for you sooner or later.

Finally i have made a decision to do this experiment generating more Bitcoins by buying shitcoins . About which i was talking on my video on YouTube in march 2019. So basically my plan was to buy some alt-coins with Bitcoin and in that way generate more Bitcoins. I have made this decision because most of the alt-coins has reached lowest points against BTC in my opinion. And proving by history they usually bounce of it. Another big reason is that Bitcoin halving is due in May 2020. This could spike up Bitcoin price and alt-coins could possible dragged with it. I cannot guarantee i will succeed but i will do an update every month or quarter on YouTube channel how am im doing with this chosen portfolio. I have a good feeling i will succeed, as i am not Bitcoin maximal and shit-coin minimalist. I am quite good at recognizing innovation. Few of my purchased coins potentially could do much better then Bitcoin price in nearest future.

So the plan is to spend 2 BTC and buy 10 alt-coins. 0.2 Bitcoin each alt-coin. I am using binance to purchase these coins and i will add them in my portfolio tracker https://www.cryptocompare.com/portfolio/ . This place is very nice where to track your crypto portfolio from desktop. I do believe 99% alt-coins are scam and will fail in future, but there also will be some who will survive. The reason i think im going to succeed is not only that these projects are useful. But i only need 1 alt-coin to do 10x in bull market against btc and the rest can fail to brake even.

My top 10 alt-coins purchased and the reasons behind it :

Ethereum - By dapp platform stats Ethereum is winning every other gen2-gen3 blockchains which are Tron,Eos etc in every aspect. Built Dapps, new users,existing users,volume and so on. Users and developers are the main key for s block-chain project to succeed. Ethereum has issues yes, there is not much room to grow. But there is constant development going on to increase platforms usability. Another thing is DeFi (decentralized finance) which got very popular in 2019 . Which basically brings banking to block-chain. This new turn on Ethereum is gaining momentum and growing every day. This will be huge in my opinion in 2020.

Chainlink - Chainlink is something unique. Currently Block-chains smart contracts cannot record data on them from outside world, they can do only on chain data. Which is timestamps,block numbers, transaction value. On their own they cannot listen to outside world which is called of chain data. But Chainlink fixes this issue, feeding this information trough decentralized oracles to smart contracts. It really made this utility token very popular in 2019, because of their massive partnership with google cloud. And on top of that they already have working product and it is been used by numerous crypto projects. It currently is looking the biggest contender to fix this issue what block chains has.

Basic attention token ( BAT) - is solving Advertisers and Content creators as myself problem ,what we have currently. For example Google collects about 40-50% add revenue from YouTube adds. Basic attention token ( BAT) solves this issue with their Brave browser. Brave browser allows you to tip your favorite content creators and block companies which collects your privacy data. So how does it work , Advertiser purchases advertisement with BAT tokens which goes to users and content creators. You actually are getting paid to watch adds. So it disables the middle man like google in this case who is taking 50% cut. Technically if Brave browser platform grows, price should increase.
Monero - Monero is a privacy coin. I do believe that privacy coins will be very demanded in future. As block-chains are getting bigger and bigger adoption, eventually governments will crack down on them. And will develop software which will allow them to trace and get user privacy data. This could happen already this year, as recent statements from EU leaders are they need more regulation on Crypto and block-chain. Monero is one of the oldest privacy coin out there. And these events around possibly could spike up Monero price. I don't want to hype it to much, but privacy was one of the main feature why Bitcoin was invented.
Neo - neo is 3rd generation blockchain similar as Ethereum. Neo comes out of China, which is one of the main reasons why im choosing this smart contract platform. Recent statement from Chinese president Xi Jinping that they have to adopt block-chain technology  in their country. This statement made me very bullish on NEO. 3rd generation block-chain platforms really will kick of in 2020, just because the possibilities can be developed on them. I don't really think yet we have figured out what can be deployed on these platforms. We can see that as time goes by, new things are been figured out like DeFi, games, fundraising and many more. Also the price on NEO has drooped about 20x since all time high. And recent volume has been growing on NEO platform. So fingers cross, Neo going to bring us honey.
Cosmos (ATOM)
IOTA (MIOTA)
Synthetix (SNX)
Tezos (XTZ)
Cardano (ADA)

I have gone trough these projects social media channels and looked how active is the community. GitHub, is there any active development on their platform. Also is there any fundamentals and working product behind it. These are the main reasons i have picked these coins for my challenge. This is not any financial advice, i'm just looking to do a challenge/research. Is this a way to increase bitcoin in bull market by buying alt-coins. I'm playing this safe and choosing the coins from top 50 in coin-market cup. Because i do believe if coin is valuable it should at-least have some value in bear market.

AMD graphic cards has been very popular for mining, specially for ethereum mining. They have been best price per has and hash per watt since ethereum launch. Previous generation cards (RX 470 and RX570) was widely used on mining farms. Also the latest generation cards RX5700 has now been very efficient for mining ETH. I do understand that Profit is still very low to invest in GPU mining rigs, better choice would be to purchase coins now. But if the markets returns where it was in 2017/2018 , this would be the mining card to choose. As they are quite efficient.

So the test bench i have :

12xGPU all in one case
12x RX5700 MSI 8gb graphic cards
2300w power supply
Best Results for mining Ethereum  got from this setup with 100 accepted shares:

640 mh/s
1770 watts


There is settings to add in Phoenix ethereum miner :

-openclLocalWork 128
-openclGlobalMultiplier 4096


By adding these 2 values to configuration you would be available to reach up to 70mh/s per GPU but with 30-50% invalid shares. Tried to change OC on graphic cards but that does not help.

So StrongU STU-U6 miner for X11 mining algorithm is been a big failure. On pre-sale few month ago i purchased it with advertised setting 660gh/s at 1300w .Which to me looked like a very attractive deal. But as usual with Chinese asic manufacturers there are problems, the deal seemed to good to be true. So finally we have received the miner which supposed to deliver in October 2019, but got delivered in December 2019. And delivered not as it was advertised, received specs :

440 GH/s mining speed
2050 power usage from the wall
This supposed to be the most efficient asic miner for Dash coin , as the Spondolies SPx36 miner is very overpriced and uses lot more power. Dont get me wrong StrongU STU-U6 is still most efficient publicly available Dash Coin miner. But it is not as efficient as it was advertised. My power cost is quite high and watt per hash was 2x better when pre-ordered, and received a miner which nearly doesn’t cover my power cost.

I seen some posts that some people have ordered before me and have received miner with the specs it was advertised. So i assume they have had some bad silicon run or some other issues why they cannot reach full performance.

Has anyone received full performance 660gh at 1300w?

So Monero Hardfork has executed set at block number 1978433 .Which has been successful as they usually are. Now there is new mining algorithm for Monero , and this change has made previous mining hardware obsolete. What I mean by that, there is more profitable hardware which are CPUs to mine monero. Previously most efficient was GPUs.
In my case most efficient hardware is Ryzen 9 CPUs, which gets me best watt per hash. Some people this might be different. As the electric and hardware prices changes different places on the planet Earth.
I just wanted to follow up on mining probability, what is going on and what are the current changes.  So after about 48 hours in new algorithm RandomX, Total network has stabilized at around 2.5x which is 750mh , network hashrate before RandomX was around 300mh/s

This was expected, for example if we had monero mining rig 6xGPU RX570 which on average was giving 5000 hashes price (1300euro)
Current hardware Ryzen 9 mining rig (800-900euro) gives you on average 13000 h/s which about 2.5x cheaper hashrate then on previous mining algorithm . Pluss the watt per hash is much more less then the GPU rigs.
Total network hasrate could increase even more, but I don’t expect it to increase that much anymore. As the profit is just not there, and the roi isn’t that fast.
Currently calculators show 0.9 XMR a month with one Ryzen 9 CPU.
Im just curios now what is going to happen with previous  Monero Network mining hardware is it going to hit other Networks or be sold in open market. I will probably do a more close follow up on few weeks and will see where it stands.

RX5700 series graphic cards has been out for few month now. But drivers for mining from AMD hasn’t been the best. Recently most popular mining OS Simple-mining and hiveOS has added support for these graphic cards. It is not perfect but mining is doable on these cards now, and the results are impressive. Im not saying here GPU mining is now profitable, you still have to be mining fanatic like i am to build GPU mining rig with new hardware.

My setup for 324mh/s mining rig:

12gpu all in one mining rig case
5x RX5700
1xRX5700XT
hiveOS mining software


Over clocks used :

Core Clock 1340
Core Voltage 800
Memory clock 930-950


My setup for 500 mh/s mining rig :

12gpu all in one mining rig case
5x RX5700
1xRX5700XT
6xRX570  4gb MSI gaming
hiveOS mining software  https://hiveos.farm/install/
Over clocks used :

Core Clock 1340 (RX5700) 1100(RX570)
Core Voltage 800
Memory clock 930-950(RX5700) 2030(RX570)


There is nearly no difference in hash-rate RX5700 and RX5700XT . It is no point spending extra 20% on gpu to increase hashrate by less then 1%. So if you are mining Ethereum stick to RX5700

Video Review: https://www.youtube.com/watch?v=Ci0SAtrpaKs

Test bench setup :

Ryzen 9 3900x with stock air cooler

2x Gskill 3000 16gb C15 RAM modules

MSI B450 Tomahawk MAX motherboard

1xRX5700 for image

Superflower 750w GOLD powersupply

As there are few of the coins switched to RandomX mining algorithm already and one of them is Loki. So on stock settings everything out of the box we where hashing Loki at 11500 h/s. Which is about 5x then in our previous best tests with Intel i7 8700k out of the box 2360 h/s. Power usage from wall is 260w.

So we tried to push little more speed on the Ryzen 9 CPU , by overclocking it in motherboard BIOS. Changes done :

OC Explore mode to expert

CPU OC ratio to 4100 mhz

A-XMP to enabled

Precision Boost Overdrive to disabled

Play with DRAM timings (lower the values)

CPU core voltage to 1.250v

Increased Dram voltage 1.300v

This setting got me up to 12650 h/s mining RandomX. I was playing around with different kind of ram stick , and seen significant mining performance decrease with lower performance ram. So i have on the way 4x3600mhz 8gb stick and will do a proper performance test when they arrive.

So the 12650 h/s if you would be available mine monero today would be 3.5 usd , even that it got 10% price drop today. But you know it is not the case, impossible to predict what kind of total network hashrate will be when Randomx launches. As the total network mining structure will change and the current hardware will be unprofitable. Current Monero network hashrate is around 300 mh/s.

Profitability with Ryzen 9 mining Loki which is also RandomX mining algorithm. Daily profitability is 0.70usd

Im eager to see what RandomX mining will bring to Monero mining. What is your thoughts?

HiveOS is the ultimate mining monitoring and control tool for your mining operation. Specially if you do have large mining farm, it is very useful and very easy to setup. So i have created installation guide with Flasher utility. In simple words plugin usb or any other hardrive before booting mining rig. And it will install hiveOS to your mining rig hard-drive. But before that your will need usb stick or ssd and hiveos account. If you dont have one here is link how to create one here.

Se the steps for gpu rig installation are :

Download hiveOS flasher latest version http://download.hiveos.farm/hive-flasher-20180910.7z

Also you will need installation tool (hdd raw copy tool or  Etcher) http://download.hiveos.farm/



Download latest GPU hiveOS image https://hiveos.farm/install/



When all the downloads are finished save and unpack them in one folder, this way will be easier to work with. For installation to flash-drive i will be using Etcher.So insert your usb flashdrive into PC and choose Flasher image in Etcher to load on this usb drive.


After you have flashed your hard-drive with hiveOS flasher, next thing is to copy over latest hiveOS image file.

Next edit your flasher sample-rig text file and insert your farmhash , you can find your farm hash in your hiveos account under farm settings.

Now your hard-drive is ready for flashing, you can insert it in your mining rig. Boot up and go into motherboard bios, select primary boot option from your hiveos flashing utility.

After reboot it will start to install hiveos on your mining rig hard-drive. When it will finish , it will shutdown your system

Then remove your flashing utility from mining rig and boot. It should automatically connect to your hiveos account.

Upgrade your miners and start hashing till asics and fpga haven't returned back.
Waiting for network to stabilize to see most accurate profits.
So far profits seems to increase.

So i have been starting to test some hardware for RandomX. What i think i will be doing is upgrading my current rigs with high end CPUs. And do dual mining, mine ethereum with graphic cards and monero with CPU for example with the same mining rig. Think this would be the most optimal way, to not spend any more money on new hardware, just the CPU. Only problem i face is that, by benchmark testing https://randomx.monerobenchmarks.info/ . Ryzen latest CPUs seems to be most efficient when it comes down to RandomX mining. But most of my mining rigs are built on Intel boards. I have couple ideas what i think i will implement in my next tutorials.

But in this i want to go trough some Intel CPUs and see what are the benchmarks. The only thing i forgot measure the power usage in mining process. But this is not a big deal, you can look up CPU power usage by its maximum performance. Also in testing i didn’t use any OC on CPUs, all of them are stock. I have been testing these CPU on hiveOS, where you can launch multiple miners simultaneously. And this allows me to easy mine different coins with same hardware from one rig.

1.Intel Celeron G3900 , it is one of the cheapest CPU what im using for most on my mining rig builds.This CPU retail price is about 40€. Performance/benchmark – 450 h/s. Which is about the same as one RX 570 on new RandomX mining Algorithm.

2. Intel Pentium G4400 , also one of the low end CPU from Intel. This CPU retail price is about 50€.  Performance/benchmark – 725 h/s. Which is equivalent about the same as two RX 570 on new RandomX mining Algorithm.

3. Intel i5 7600. This CPU retail price is about 280€ . Performance/benchmark – 1.63 kh/s. Which is equivalent about the same as two Vega 56 on new RandomX mining Algorithm.

4. Intel i7 8700k. This CPU retail price is about 450€ . Performance/benchmark – 2.36 kh/s. Which is equivalent about the same as 4 Vega 56 on new RandomX mining Algorithm.



Some people are claiming Intel i7 8700k overclocked can reach 3.5-4 kh/s. Which is a great performance for one CPU if you are comparing it to Graphic cards. But if you are using lates Ryzen 3800 or 3900 series cpu the performance is even better. Some  Ryzen 9 3900 overclocked reaching 14 big fat kh/s , which is a monster RandomX mining CPU in terms of price per hash and hash per watt. I have Some Ryzen CPUs on the way and will do some testing also, so subscribe it to not miss it.

It will be interesting to see what RandomX will do to Monero hashrate. In my opinion it will be higher as it is in a first week of algorithm switch as the CPU are much more efficient as gpu for it.

We will have some introduction about staking, staking in block chain isn’t anything new. It has been talked for a while now , and also one of the top Block chains Ethereum are trying this to implement since 2016. So I will be staking some ATOM tokens on Cosmos block chain and will be showing how i am doing this. Cosmos is quite new block chain , or what people call in 3.0 block chain. Where they have some unique features where you basically can plug in any block chain into Cosmos network of block chains and make it more efficiently. In few words how I understand staking in simple way. In Proof of work chain security, you have capital , you buy for example Antminer S17. Than you connect it to mining pool, and by doing this you get block rewards depending on how big hash rate you have. So in the Cosmos Proof of stake security, very similar. You again invest your capital and buy Atom coins. Then there is these validators , similar as pow has mining pools. You send your coins to these validators trough smart contract, which is called delegation . And in this way you get part of the block reward depending on how much Atom coin you have, the more Atoms you have the bigger piece of “pie”.

So lets get in to in and stake some Atoms. First of all I would recommend you to use secure hardware wallet for this as ledger nano, what I will be doing. You want to download Cosmos app in ledger nano app store. If you don’t see it in app store you might need to enable developer mode in your settings, as it is still in development. For simplicity purpose i’m using web wallet where I will be using my ledger nano to access my wallet. You can find multiple cosmos wallets  in here https://hub.cosmos.network/

For this tutorial ill be using web wallet from this list https://lunie.io .

The next steps are very simple :

open this web wallet with your ledger nano device
you will see your wallet address there, transfer some ATOM tokens to it.
When ATOM tokens is in you wallet start staking
Click on Staking tap, choose validator you want to Delegate.
Enter amount of tokens you want to delegate and confirm transaction with your ledger nano.
It is very simple, check out the video down below this might help you more.

As soon as you will delegate your coins you will start getting block rewards on amount of coins you have. There is no fixed block reward on cosmos block chain, it will be an average 7-20% yearly. It is calculated compound interest as I would say. Depending on how many total Cosmos network ATOM tokens are staked, if they will be less then 2/3 of total amount Atom. Then the block rewards will be higher closer to 20%. If staked ATOMS will be more from total of 2/3 then you will get closer to 7%. Also you need to note that if you want to finish staking (delegating) your coins, it will take 3 weeks to arrive back in your wallet. But if you want to change to delegate your Atom to different validator it will be done without waiting. I hope it was easy to understand as it was for me 😊

If you are new to crypto currency mining or you want to find out what is current profitability in crypto currency mining , you want to stick around for this one.

Most of you who is in mining or has ever wanted to invest in mining here is for making profits. About 99% miners are looking to make some kind of profit in crypto mining, only about 1% or less here is for supporting networks. Mining might be high risk and high reward business category. As it is very unpredictable it is hard to tell what you will be earning after 1 week or one month. We can only look into mining calculators today and see what is the profitability. Because tomorrow crypto currency which you are mining, price could collapse or skyrocket. Who has been in crypto for a while now , will understand what i’m talking about. Mining profits does depend on few factors like :

• your equipment costs
  
• mining software efficiency
  
  • your equipment efficiency
    
  • your energy costs
    
    • do you have any extra costs like (rent,security,how expensive is your location, equipment cooling costs)
  
  As in any business you are looking for your ROI as soon as possible, and doing most efficient way will always be the most less risky way. Let me give you and example 2 guys (John and Noah) start mining at the same time , they buy same mining equipment for the same price. Lets say Antminer S9 , John is mining from his house garage and pays 10c for 1kwh and the Noah sends his equipment to data center and gets deal for 5c kwh all inclusive. Of course the Noah whose power is 5c for 1kwh will do his ROI much faster, so for him it will be less risky investment.
  
  Always this is not the case and there is possibility that newer mining hardware will be released. In that situation both of the guys might loose their investment , as the new hardware might be more efficient. And there wont be any profit using the previous generation hardware.
  
  Im in mining business for over 3 years now and have been trough up and downs. Have gained a lot of experience by mining and also distributing hardware. Have made big gains and also very big looses buy buying large quantities of asic mining rigs. Asic mining is the most dangerous, but people still do it as it is sometimes more rewarding then gpu mining. A have got burned a lot of on the asic equipment, but not so much with gpu miners. The beauty about gpu miners is that if you choose the right hardware there is a lot of variety coins of to choose for mining. And i could bring you stable profit.
  
  So before you get in mining , do your business plan first. Do all the calculations, think all the details trough, all the small expenses. Cause everyone case is different, someones power might be slightly more expensive. But he is using somewhere else the heat produced from mining, and saves other expenses like for example heating or growing tomatoes costs. Don’t forget also to check current mining equipment profitability, best sites to check is :
  
  https://whattomine.com  for GPU mining
  https://www.asicminervalue.com for newest ASIC miner hardware
  But be very careful about asic miner profitability, dont get flashed about seeing high profitability rating. Always remember if new miner is released on preorder, the profit will be much lower when you will receive miner. And the second thing that newer generation miner lot more efficient miner could be released by different asic miner manufacturer. In that way you might not even get your invested money back. If i would suggest Asic mining , i would say that choose to mine coins like Litecoin or Bitcoin. Because these coins are one of the oldest, and the mining has got very advanced on them. Newer generation miners wont be so often released and wont be as highly overate profitability.

  Did i miss anything ?

Sapphire 16gb RX570 mining card testing and review. So this card was released from Sapphire about 5 month ago and currently are priced at 329 usd on their website. Which to me seems quite expensive after i have done some benchmark testing. I can see that this price has dropped as previously priced, couple month ago it was at 399 usd.

 

I’m not surprise that the price of this graphic card is drooping , as the mining profits are not just great currently on most of the AMD cards. Also the performance for mining isn’t great on this graphic card. These are the benchmarks we where getting on this graphic card :

ethereum 31.5mh/s
Monero 900 h/s
grin coin cocaroo 29 (1.8 gp/s) cocaroo 31 (0.4 gp/s)
This card has the same base line as RX570 and it has extra 16gb gddr5 memory. Currently RX570 4gb trading at 100-150usd which is more then twice cheaper then the 16gb version. This doesn’t make sense to me that this card is trading twice as expensive as the RX570 4gb version for about the same performance in mining. Yes i know that Sapphire is advertising this card as for mining grin coin on mining algorithm cocaroo 31. Which needs high end cards and at-least 8gb of memory , also this algorithm is for asic miners. But currently we do not have any asics for Grin out there, so you can use these graphic cards. This 16gb RX570 on this algorithm is very efficient yes, it does the same speed as 1080TI. But i have a really good question is it really worth it, even if it is twice as cheap as 1080ti, No it is not. The profitability is just not there. It makes more sense to buy for example (1660ti which is lot cheaper then RX570 16gb which will bring in more Grin revenue mining cocaroo 29 ).

1660ti mining profits mining grin on cocaroo 29:

Sapphire RX570 16 mining Grin cocaroo 31

So overall my thoughts on this card is, it must be some Sapphire marketing trick. Where they are trying to sell their unsold RX570 graphic cards. Where they have added 16gb more to just get rid of them. Don’t get me wrong i would also buy this card if it was priced same price as RX570 4gb as mining performance is nearly the same.

Would you buy it? Do you own it?

GTX 1660ti graphic cards where releases somewhere in February 2019. And they are value graphic cards from Nvidia, so it means good price , low power usage and very efficient for mining. Which makes the one of the most efficient mining graphic cards for mining some of the cryptos. Probably after our test the most efficient mining is on Ethereum , Raven and Grin coin mining.


We where testing these in hiveOS , and these are the results we are getting:

1660 TI mining benchmarks      Overclock used on rig   
Currency      H/s per card   H/s per 6xgpu rig   Power usage per 6xgpu rig   Core   Memory   Power Limit   Miner software used in hiveOS

Power usage is really great on these cards, so at least there is some profit for mining in such tough times for miners. Like some of the other graphic cards even doesn’t cover power costs for mining. This means if you are using these cards , you can stay longer in the game without loosing money. Which is crucial for large mining farms, as we have seen a lot of them shutting down as they cannot cover the power costs.

Antminer Z9 review mining Zcash.

Antminer Z9 in one of the newest ASIC miners From Bitmain for mining Equihash Like Zcash , Zclassic , Zen Cash and other Shit-coins. So we got the miner for Tests couple days ago, as usually Bitmain with the specs are there are advertising on their website they are on point. Miners are usually as efficient or more.
To setup Antminer Z9 is the same way as any other Bitmain asic miners, you put in your pool address type in wallet info and you are good to go. We did connect this miner to Flypool to mine Zcahs.

After the setup miner stats hashing nearly instantly , it does connect to mining pool much more faster then Antminer E3. Which took about 7-10 minutes to start hashing.
The results we got was :
•   42 Kh/s
•   1000 Watts
As many of you know Antminer Z9 mini was possible to overclock and get more then 50%extra hashrate which of course does make your ROI much more faster. But Bitmain has removed the option to OC as much In this software version. And there is only 2 overclock options now :
•   “Balance” which is the stock setting 500mhz
•   “Turbo” which has OC 550mhz

So when using overclock “Turbo” results are:
•   50kh/s
•   1100w

We did try also HTML hach which seems to didn’t work, as you are trying some OC which doesn’t exist, miner automatically restets to stock. Also we tried to edit CGminer configuration file which also was not supported.
Currently equihash miners are the only one of the most profitable as rest of the miners barely covers power costs and in some cases it doesn’t. For how long this is going to be, I dont know . As usually these asic miner manufacturers manufacture so many miners that mining difficulty increases so much that there is no mining profit. Probably expecting to 0 profit in 1-3 month if the prices wont change.

Overwall thoughts about miner :
Miner working stable and profitable. After testing 2 miners , one hashing board died on one miner. Turning off after 30 minutes of mining. Tried software recovery which also didn’t help.

We have reached now lowest point at Ethereum network hash-rate since January.


Think we will find the bottom very soon, only scam can go to 0, dont think ETH is any Scam.

I know maybe it is not the right time to make a post like this, as the mining profit has reached the lowest point in whole year. But we are looking for an options that we do not need to switch mining rigs of, because not possible to cover power costs.

To compare ,lets see the efficiency of 8 x GPU RX570 mining rig (average benchmarks 220mh/s at 1000 Watts, price 3000usd) :

• 4.55 watts per every mh/s
• price per mh/s 13.64 usd per every mh/s
• Currently Daily profit = 0.87usd after paying for power 0.11usd (06.09.2018)
• Currently ROI 2857 days

Now lets see 8xGTX 1080 gpu mining rig ( average benchmarks 310 mh/s at 1100 Watts , price 5000 usd ) :

• 3.55 Watts per every mh/s
• price per mh/s 16.13 usd per every mh/s
• Currently Daily profit = 2.21usd after paying for power 0.11usd (06.09.2018
• Currently ROI 2268 days

Neither of these miners seems very profitable, GPU probably cannot handle even such long lifetime to make your investment back. All of this is of course as the mining profits has reached lowest point in a year.



But as we where looking for efficiency we have a winner which is Ethereum mining rig 310mh/s

As mining profits as reached so low now that we cannot cove even the power costs, and if you want to run your mining rig as long as possible without  a loos you need to run efficient mining rig. Nvidia mining rigs can be quite expensive and if the mining profits would be slightly more best choise would be to choose Rx570 mining rig as it is much cheaper. Also another big factor is power cost if it is very low, less then most of the miners. I would go for RX570 mining rigs as your return would be much faster.

I know many people are mining at loos , this choice have to take yourself. Do you want to gamble or not.
