Bitcoin solo mining with cpu

[BlackMachine]

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!

 

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.

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.

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

Code:

0.0000000000000000000048924699290284694

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.
