hi there, i just want to know if there is a chance that i can find a block even my hashrate is 2231 khash/s?

Sure there is a chance, much like there is a chance to win the lottery if you buy a ticket.. There is a chance but it is very small..

At 2231 khash/s it will take approximately 1040943295 days, 14 hours, 1 minute, 47 seconds at the current difficulty..

Are you sure you want to do Solo Mining? Why don't you just mining in a Pool? It will be more effective I think.

But he can still play the lottery - just in case he wins :)

But seriously OP, it's not worth it.

A cpu is too insignificant to mine anything in a pool. Better to gamble and mine solo.

But, which one will be more profitable? Pool or Solo?

With his hash rate...

Solo = Gambling to win big
Pool = Extremely low earnings

Neither. Both will return zero. You'll never find a block solo, and no pool would ever pay out the one share you'd find every hour at that hashrate as the denomination would be too small to pay out even after a year.

don't waste your time with that abysmally low hashrate, it's pointless to mine with such power, buy bitcoin instead they have a fair price even for average joe now

or you can invest in some cloud(hashnest and bit-x, the rest are not that good)

I had the same idea, I love the thought of the pop-up coming and saying that I have mined a block, but unfortunately it is near impossible.
I turned on the mining in Bitcoin-qt on my crappy old PC, left it for a few hours, then got sick of my PC running even more slowly than normal, so turned it off!

I doubt you have the patience to really give it a go, and if you do, you will still find nothing! so I guess I wouldn't recommend it!

Why not, think your chances of winning the lottery might be higher, but you've got to be in it to win it.

Hey! If you have 2 computers, you can double your hash! It's like having 2 lottery tickets!

2 times 0 (effective chance of 'winning') is still 0

Yes, I would say there is a chance but it is extremely extremely small.

Listen to what -ck says, he is 100% correct and legit.

woah that's so many days,
i wonder how old i will be if i try to mine a block

That is on average.  You MAY find it on your first try or never.  That is the 'luck' that people refer to.

But people still buy lottery tickets don't they? Funny isn't it, knowing that you've pretty much got no chance winning it, but you still have that one small glint in the distance. I guess people know that they can win big.

Anyways, I don't think at 2231kH/s, you'll be able to get any Bitcoin, both with pool and solo mining.

CPU? Better to mine altcoins rather than Bitcoin :D

Mining in a pool is a sure loss because of electricity cost. Mining solo is also losing money but has astronomically low chance to find a block of 25 btc

no chance dude :)

IMHO OP is better off spending $1 per day or $30ish dollars pm on buying bitcoin and that's surely a much higher return overall.

Good idea.  It is better to buy $1 / day worth of btc or $5/ week instead of trying to mine with a cpu.

Let's put it this way - you are at 2.2 mh/s with your CPU and gobbling electricity.  You could buy a USB miner (block erupter) from eBay for $12 and do 335 mh/s (equivalent to having 152 of your computers hashing away!) and use WAY WAY less electricity doing it.  Your lottery ticket just got many many times multiplied!!  Still about a 0% chance overall, but with just the electricity you will save for that lottery ticket - you will thank me!  :)  Good luck!

 

Just did the math:

You would have exactly a 0.000000000082930% chance of hitting a block over a 1 year period running at 99.999% efficiency 24/7 (assuming difficulty remains static)

*And yeah, that's fraction of a single percent!

:-P

So my 486 DX2 66 is useless?  I'm gonna kill myself now  >:(

Oh no no, it's not useless at all - you can use it to prop open the door to the miner equipment room for better cooling!!  Of course that is a waste of a pretty powerful machine, I've got some old 286's in the garage I could send you that can do the same thing.  Of course the cases on those 286's are huge so it may slightly decrease your cooling ability due to the size and restricted airflow but...   ;D

Nothing is impossible.
If youre lucky you might find a block. Mining in a pool is useless for a cpu. If your computer is free and you dont need to use it, why not?
But overloading a CPU damages it, so dont try to somehow overclock the cpu or give it a big work load for a long time span

I suggest not doing this as i left a oldish computer running for 2 months and gained 0 btc from this, was only testing it our myself with no luck only a electricity bill to pay.

Was around the same hash rate too.

What would the math be with 17th?

;D cpu mining on bitcoin, this is a totally wasted gamble.. sell that junk old pc, rent a real miner and point it at ck's solo pool.

Even if you did mine a blocks after a few years, the power costs would end up wrecking you.

With 17TH/s you would expect to find a block in about 139 days with the current network difficulty.

You have the chance but since it is minimal I recommend searching a better solution. BTC mining has gone through a significant development since it was born and now there are some "new", effective possibilities as well as some fading ones and solo CPU mining is part of the last unless you have some kind of super computer. You always can play the lottery, though.

Supercomputers aren't cheap to run. Just ask any Cray customer about their cooling and electric bill.

You have just mentioned some very important points there. Electric bill is one important factor to calculate in but in addition You need to care of proper cooling as well that also is a factor you are advised to keep on your mind while it is not a problem. A friend's computer flew away because he has not minded mining necessitated advanced cooling that in many cases were different than the cooling you were using for your current daily tasks on your computer.

Solo mining, already puts you at a large loss, even with MANY GPU's, or even ASIC's. And mining Bitcoin, with your CPU, solo, is surely not going to make you any considerable amount of money. You're risking your CPU running at 100% 24/7 just to maybe make a cent every few days. It's simply not worth it, but it does seem as if you do have a good CPU so maybe you can mine some Altcoin's that are ASIC resistant.

That is just 3 million years. I wonder if bitcoin will exist then. or better if life on Earth will exist.

well mining with cpu its for btc very low porfit mining alt coin in pool wiht with cpu you heed to see if theres like some cpu good coin like frozen or soo i cant remebem much but frozen coin was cpu.

ofc there is always a change, the minimal possibility is always there, but you know, dont expect it, so if i was you i will  quit that idea asap and try to made something more profitable with my cpu ;)

If a computer is at idle, the power consumption is still quite high. Buying a block erupter and hashing it using your computer as the host can be expensive. If you use raspberry pi, it will cost $30+ but it depends on what you currently have. Either way, it isn't feasible.

At this point in any persons bitcoin mining operation is going to cost some good amounts of money.

And thats if youre okay with also if the price does fall or not. I`d just buy more into the legit cloud mining services out there that accept credit cards so you can also protect if something does go bad.

cpu mining in 2015? LOL, good luck to you, OP. :P

bc.info has an interesting statistic available on their API page that most people overlook. Probability.

It's the probability that one would find a valid block with just one single hash.

https://blockchain.info/q/probability

Current chance % to find a valid block with a single hash is


If you are CPU mining at 2 million hashes per second then you can knock off a few leading zeros to the above figure  ;)

....
Then you have average # of hashes required to find a block.
