hi guys i see many block mined on blockchain without any pool .. is it possible to mine bitcoin without attaching your hardware with the pool?
i know there are big chances of accepted share on pool , but what about without pool?

It's possible, but chance to get a block is so low you won't have it good, it's better with a pool.

Yep, you can mine against your Bitcoin-Qt client in server mode.

If you have a really good luck, than you will find a block even with 1TH, but i don't recommend you waiting for that to happen, join pool and take a share, so no need for you to risk.

Yeah, not worth it.  Solo mining alts can be OK but with Bitcoin it doesn't make sense without a large scale farm, haha.

All it takes is luck my friend. You get lucky and a block is yours. How much can you really earn with less that 1 TH on a pool?  You are better off I think just trying to get lucky solo mining.

If you solo mine with small amount of power, it would be like winning the lottery. Some people have turned old USB hardware thats not profitable as a miner, and turned them into a "lottery ticket". Its possible but not likely. You would be better off join a pool. 

I'm one of those.  I have 5 Antminer U2 sticks that I use to solo mine.  I haven't solved a block yet, but the cost to run the things is minimal (they are controlled by a raspberry pi) so I keep it going.  Chances are exceedingly slim that I will solve a block, but why not let them hash away and try?  The earnings on a pool are dust anyway.

I'm thinking of doing something similar.  Do we have any recent reports of low hash miners who got lucky?  I was thinking of mining with very little, just for the heck of it, like a lottery ticket.  But, I'd like to have some hope, in terms of someone else who's gotten lucky recently with very little hashrate.  I'm sure it must happen all the time...

PS what are requirements for Antminer U2 sticks?  Can I run just on a nothing-special laptop?

The Antminer U2 sticks are pretty much plug and play.  Both cgminer and bfgminer support them out of the box.  On windows, you might have to install some drivers (I'm not sure since I don't run Windows boxes), but I remember reading something about Zadig... at any rate, if you're going the rPi route, it's exceeding simple:

1) Install your favorite mining software
2) plug the U2 into USB port
3) start mining software
4) Pray that you hit :)

Personally, I mine directly to the Bitcoin core running on another machine on my network (it also runs my local p2pool node).  However, a number of people use "bit solo" pool so they don't need to be running a local node.  The pool is obviously less setup; however, you have to trust that the operator is actually going to pay you out the 25BTC.  So far, they've found 1 block and indeed the miner was paid, so they've got a 100% track record.

From BitcoinX Profitability Calculator for 1TH/s

Average generation time for a block (solo) 2 years, 131 days (can vary greatly depending on your luck)

Will you wait ~2-3 years to MAYBE get a block worth about $15,000 right now?

You'll make a lot more in a pool in that time frame.

Solo mining I'd say you need at least 10TH/s to make a basic, pool mining type return.

I wouldn't do it below 50TH/s myself.

Cloud mining is always an option also.

Ha, yes it literally is like a lottery ticket. The comparison is awesome! The only depressing thing is that your lottery tickets' chances of winning get smaller and smaller every 12 days, unless you invest in a new miner lottery ticket

If we're going to continue the analogy, you should have written, "your lottery tickets' chances of winning get smaller and smaller every 2016 jackpots..." :)

Sure you can mine solo.
It's a headache to set up though - you can also mine solo by mining at bitsolo.net
You're basically mining solo but they do all the background work for you.


I hate it when people say: "It's impossible, don't do it." Heck, we all know what the odds are (or not) but hey, if you wanna go solo, go solo! Whatever you wanna do dude!

I haven't tried solo mining since I gave up my orig Antminer.
Anyone know if there are any new, special or helpful, arguments I should add to my startup bat file to solo mine more effectively?
I remember to start the qt as server and mine to local ip;  the rest I will have to figure out again.
I realized today that with my new miners now online I am contributing over 60% of the hashing power of the pool I was mining at but only getting about 15% of the coins. And that is before pool fees etc take another 2.5% off the top. (Yes it is a small pool and is my secondary mining setup, my main is a large bitcoin pool where I am less than 1% of hash power).
I think it is worth trying again now that I have these (annoyingly loud) machines kicking out 1.2 THs.
Any advice would be appreciated

Just as much chance of accepted shares while solo-mining just highly unlikely any of your solo transactions will be the "lucky one" ;-)

Unless your messing with >65-70TH at this moment or you have the ball's of a Spartan you'll probably just want to stick to pooled mining :-)

Using a raspberry pi is the way to go in many cases for controlling ASIC's, low power consumption, easy setup. I like using minepeon for my setup, seems to work well. Its running 24/7, and it only cost a few cents a day to run. Its kind of fun knowing that maybe, just maybe you might wake up to 25btc one day. lol

IF your speed is too much high you can mine mining through pools is benefit because payout is fast even at 1 GHS speed

How is that possible?

The math doesn't add up.

You'll make more in that time frame if you don't hit but less than if you hit because pool operator takes a cut.

Have you seen the difficulty graph for the past 1 year?  If you start mining now with some miniscule hashrate you will eek out a small amount on a pool and you will continue to get less and less each month.  You will also have a less and less chance of finding a block as each difficulty period passes by.   So last December your chance of finding a block with a given amount of hashrate was 20X as high (since difficulty is 20x as high).  In an additional 2 years figure difficulty goes up maybe 20x more making it even more unlikely you wil find a block.

The pool fees are at most 5% and miniscule compared to a 20x increase in difficulty.  Also in 2 years the block halving will occur and then you will only get 12.5BTC.

The math does add up, because it's math that got the expected values.
You can avoid fees by mining on a pool without them.

I have an Antminer U2 on my works laptop, so I only really mine while I'm at work.  I am with Slushs and in all honesty, it will be a year before I even make the .01 minimum payout.  What is that £3?  I might as well be solo mining now as I'm never going to see any real return on my pool mining. 

Then again I have never really done any lotteries as I never liked their odds. 

you all guys rocks thanks for your replies understand how to mine .. now locking down the thread .. :)
