Is it worth to mine with my old computer

[ranochigo]

No. Don't mine with it. Mining bitcoin needs a heavy duty and high-end built PC. Mining in old computer is just a waste of time, you won't get anything and you will just waste your money in paying electricity bill or your computer might wear off.

I would say it isn't necessary for miners to have a high end PC if they are going to mine GPU capable coins eg. Bitcoin, litecoins. The CPU can be weaker and cheaper as it doesn't really affect hashrates. The casing cost can easily be deducted if you use milk case to provide a better airflow. Mining alt coins however, depends on what kind of algronithm you want to mine on. But since scrypt and SHA256D already have ASICs designed for them, most miners with old GPUs would just go for coins which can be GPU mined. CPU wise, not so much as most of them don't have good CPU when they build it.

No is not
You'll lose time,power and money
For me it is still profitable because I'm still mining with my 3x S5 that have 1.2 TH/s and 590W/per hour.

It's not possible to mine bitcoin with just a computer anymore. Better to get an ASIC miner. I remember seeing USB stick ASIC miners a while back, but I have no idea if they still exist now.

It is possible but you would be mining at a slower speed. USB ASICs are limited in terms of thermal output as they don't have a fan attached. It is also limited in terms of power consumption as they can't run with much power when powered from USB ports. There have been reports of people receiving faulty ones though. Nevertheless, you can consider getting it if you just want to learn more about Bitcoin. Otherwise, the cost of powering a computer as a host would already eat the profit.

I would like to mine for a little while just to understand how it`s done. My electricity costs are almost zero - I pay a flat rate as part of my condominium fees, I won`t pay anymore if I mine.

But I only have an old pc, and have no idea what equipment I would need to start mining. And I know very little about computers, other than knowing what a usb port is. I should look for a USB ASIC?

[lissandra]

I personally think its better to just sell old stuff or reasonable stuff you would sell on ebay for bitcoin.

If you can get good deals on ebay, and resell it back on here if you catch the value increase.

[silverolivia]

I dont think you need to rape your old computer. Because you barely will have any success in the end. Mining is not very profitable nowadays. And with weak hardware you wont make enough

Mine BTC requires ASICs at the moment, and most of them can be plugged to the computer using USB or other means.

An old computer can be used in the mining process, but you can't use the old computer to mine

[RealBitcoin]

You can but not bitcoin.

Anything with difficulty over 0.1 i think is impossible to get rich quick from.

However try POS coins, special mining coins (that are distributed by other forms of mining not hardware), or low difficulty altcoins.

[funtotry]

Nahh it will just slowly destroy your computer, cause heat in your house (especially since its summer right now), and give you pretty much no btc in return.
Mining BTC right now is a joke, mining litecoin/dogecoin is pretty laughable, but you might actually get something from it.
There are other shitcoins that you can mine, but they are called shitcoins for a reason.
Mining with your average computer is pretty much dead these days, unless you start your own coin, premine 50% of it, and slowly unload it once you release it.

even 0.1 is too much for a cpu, although it can be good with gpu, for cpu you need something like 0.01 to earn block fast, and since any cpu coin is almost dead you can't wasting time making 1 block per day or something

[BitcoinMagician]

I think you'd be better off selling your old computer and buying bitcoin with whatever you sell it at.

Even then, i just bought 2 old U2's, running @ 2.2 Ghs (i get about 4 Ghs continuously). They made me 1600 satoshi's in 24 hours... freebitco.in is currently paying around 700 satoshi's an hour to fill in one capcha, so i would have made more BTC just filling in 3 captha's.

I knew this from the start, and only bought them to learn about mining, but still, even with prior knowledge i would never ROI, the payout is below my expectation...

The only way to make money mining (AFAIK), is buying really efficient ASIC's (antminer S5 or something) in bulk, and getting a really good electricity rate...

And we all know faucets are horrible on pay.   Today's miners really need cheap electricity this is first thing.

And you really need asics if your going to mine.  Old computers are good for maybe a cold wallet?  But not a lot of use without losing money.

I you want to leave it on 24x7 you could have it be a bitcoin node.

I have a computer which will not used, however, it is about 4-5 years old already,
is it worth to use it to mine BTC?

If yes, how much will I expect to get in 1 month

using your old computer to directly mine bitcoin is a hard thing to do. But you can still mining bitcoin but not directly to mine bitcoin but use your old computer to POS mining or staking for altcoin. Search for the profitable POS coin such as Diamond, Hyperstake etc, and then you sell your staking coin to bitcoin

It's not a hard thing to do. You can do it easily with a program or two.

But you will lose money with electricity on PC running.  And not to mention you cannot compete against asics.  2 old usb block erupters can match sha power on hashing with great GPU's.   SHA is a asic game now.

Not only it is not worth but is impossible to mine bitcoins with a computer. It is impossible to mine with a new computer. To not speak here for a old one.

It's NOT impossible. Even when we were to where it was "impossible" to GPU mine, someone hit TWO blocks with a USB miner. It's basically just the lottery. Claiming it's impossible is naive. Are you likely to? No. But if you feel lucky, go for it.

Were talking very very low odds though.  If you just use a old pc and no asics on mining BTC it is going to be just horrible odds.  You can use a few old block erupters and be more of a lotto machine.

If you are going to do it get a raspberry PI you will pay it off in electricity savings.  And you can run the lotto machine there with a few usb miners.  Chances are you will never hit a block... but if you get very lucky not impossible.

I'll second the idea of a Pi and USB miners. Even if you never hit anything, that's ridiculously cheap (even the USB drives are pretty cheap, should be a couple dollars each at this point).

[Amph]

it may be possible to hit a block(with a very low hash) now that the diff isn't rising too much, but don't expect the same thing if the price was climbing without rest

so hironically solo mining can have a point when bitcoin remain stable, still it's better to mine altcoin with the same hash, mre profit is awaiting you
