Bitcoin Forum

Hello All,

I'm trying to find answers from 2 days now, but I'm still finding deadends.
My situation is like that: I've got a 2 little servers which are hosting VMWare machines. I would like to build up a VM to which will be connected thru proxy server and do some mining. It's my test machine at work, so it's most of the time idle.
Q1.
What mining software I could use for CPU only?
Q2.
How it should be configured? I tried to use bfgminer, but I think I'm doing something wrong
Q3.
How I can get out, if I'm behind the proxy and only HTTP,HTTPS ports are open?
Q4.
Is it possible to limit CPU usage for 20%?
Q5.
I can install this mining on 1000PC without a problem, I would like to have some mining farm
Q6.
Is this process in the background?

Thank you in advance for your help.
Cheers,

CPU mining became irrelevant in bitcoin 3 years ago. Even with 1000PCs you will spend 1000 dollars in electricity and earn not even 1 cent worth of bitcoin. So don't even bother trying to find the answers to your questions.

One can only mine bitcoin meaningfully with dedicated ASIC hardware.

You should post this in the technical section and you'll get better traffic of viewers from people that actually know the answers you're looking for. The beginners section attracts beginners.

Most mining software nowadays disables CPU mining by default due to its inefficiency.

 Some pools offer port 80 or 443 as a mining port. Eg. Bitminter.

I have tried using VMWare before and it has an option to limit CPU usage. It can be possible to do so but your performance would be heavily compromised.

Even with a thousand PC, you would still have little hashrate and use lots of electricity. Buying a single ASIC would probably outperform all of them at a lower price and lower electrical usage.

All mining softwares allow you to minimize it and you can do other things while mining.


Note that if you are using a shared server, you would probably be banned for using too much CPU resources and they will not refund you.

Go look for some CPU only alternate coin in alt-coin section, you should be able to find some pretty high profitable one but it should not last long.

You are not planing to build a farm, you are planing to use miner on other peoples computers, well you are few years late to do that with any profit.
Also, judging by your lack of knowledge, you would fail miserably in trying this, because most of the miners get reported by antiviruses, and mostly get blocked in making outband connections,unless its a modified version of original miner, or obfuscated one (but that would still trigger proactive defences that most AV's have)
Just drop it, and turn to more legal options of making money.

cheers

As mentioned earlier, CPU mining is not relevant in bitcoin anymore.

Imagine this, currently the mining capacity of bitcoin is hundreds of petahashes. A CPU with i7 processor can mine at a few kilohashes. If every single computer in the world were mining BTC as part of a botnet using their CPU power, it wouldn't be but a few hundred gigahashes of power

cpu mining is outdated by a long shoot, the same for gpu, and asic are not profitable too

It's all about the factors affecting the profitability, electrical rates, payouts and hardware cost. If the cost are low, chance ROI and profitability can be high. However, it is a gamble. The price and the difficulty is pretty volatile, you might lose your chance of ROI due to increased electrical rate or difficulty.

Best thing to do is try mining altcoins instead of going for mining bitcoin with a cpu miner .
 Bitcoin cannot really be mined with CPU due to almost lack of any hashing power

I only know cointellect software mining. If you want to mining is better to use hardware mining, don't invest in cm service too many ponzi scheme. And if you want to get profit better to mining altcoin. You can go to mining section for details

Dude forget about mining with CPU,
you will only lose your money on electricity and
hardware amortization

I doubt you'll even make some profit with cpus. CPU mining is not profitable, so is GPU mining and mining with dedicated miners (ASICS - depends on electricity costs and maintenance costs). Just drop the idea of mining. Try to get some bitcoins by working for it. Better option than mining.

The answer to your question is PoolerCPUMiner.
Get it here: http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.4-win32.zip/download

P.S.: Like everyone said, you need to check some other profitable altcoin before going into CPU Mining, as you won't be able to mine BTC at this high difficulty.

A1. Use minerd

A2. CPU mining is not for Bitcoin anymore.

A3. With Monero, there are pools that allows that with specific ports.

A4. Yes. Use cpu miner - minerd with specific command, like in Monero, so if your CPU have 8 cores, you can mine by setting it to mine with only 1 core by -t 1, or whichever value you'd like to define.

A5. Yes you can.

A6. It cannot be background as it is mining.

You're welcome.

I have run it as a background process. So it can be run in background if you want.

Look at this chart:

In 2011-2012 CPU mining was very difficult and not profitable.

Now the difficulty is ×10000 harder... So you will earn 1/10000 of your electricity cost. :P

dear All,

Thank you for you precious help. I think, I'll drop idea with BTC mining using CPU. I don't bother of electicity cost, due to I'm not the one who is paying the bill for it.
So the other idea is:
buy miner, and I would like to ask, which Miner is not too expensive (~500$)?
Thanks,

Bitmain maybe, actually im not mining especially with hardware :P
you can surfing on this section: https://bitcointalk.org/index.php?board=76.0 and choose your hardware ;)

I suggest you to buy either Antiminer S5 or Antiminer S3. Both are best miners I have seen so far.

If you really have access to a thousand computers (and you are not the one who will bear the electricity costs), you could try mining cryptonight coins (such as darknote or monero). With an 8 core AMD processor at 4000Mhz you will be able to earn around 0.001 btc daily. So with a thousand of such machines dedicated to mining you could raise up to 1 bitcoin per day...

Mining with cpu is highly unprofitable as the power needed to mine bitcoins is alot greater than your reward. Mining with your GPU is still unprofitable. I suggest you take some bitcoins and invest it in some trustworthy cloud mining sites (the ones that has been here for months). If you want you could also buy a USB miner. I have an Antminer U2 and I just lease it on leaserigs and I earn around 10k doge per week.

Bitcoin is not the only pebble on the beach. There are altcoins that are asic resistant and which can be mined only on cpu (and gpu with almost the same performance). Darknote is one such cryptocoin that doubled in bitcoin denominated price within the last few months, even despite the fact that bitcoin price also increased significantly during the same time frame...

Search ebay for bitcoin miner, you'll find several.  Used S3 goes for ~$100, good machine.  Have fun!

Buy it only from trusted sellers. I recommend you to buy from this forum instead if ebay. People here will help you if they see you are going to deal with a scammer or likely-scammer. See Computer Hardware (https://bitcointalk.org/index.php?board=75.0) sub-board to buy a miner. If you couldn't find a suitable miner, you can create a thread and "[WTB] name of the miner you want to buy" as subject/title. For example, if you want to buy 2 Anitminer S4, then create a thread with "[WTB] 2x Antinminer S4". :)
