I have installed bitcoin about 36h ago on Ubuntu 10.10. It uses the whole CPU power, quickly overheating my system.

My CPU is a Phenom II 720 tricore black edition, and I am getting some overheating with some other program, since it is 40 Cº outside. (Antipodean summer)

The client has ben generating with one core only for the whole time, but I don't see the first bitcoin yet, is this normal?

Thanks

PS: I have version 0.3.17, I downloaded the binaries, not SVN.

That should estimate the time required to get bitcoins. I'm also running the binary on 10.10 on a dual P4 set up. No overheating problems here.

My khash with one core only is 2644 on average.

The calculator say:

Average   151 days, 21 hours, 9 minutes
50%   105 days, 6 hours, 38 minutes
95%   454 days, 23 hours, 55 minutes

It is much slower that I expected. Out of curiosity, what is your P4 khash / s?

If I turn the 3 cores on (I can do that for only about a minute) the khash is 7700 - 7800

Probability   Time
Average   52 days, 3 hours, 49 minutes
50%   36 days, 3 hours, 41 minutes
95%   156 days, 6 hours, 8 minutes

considering how my fans are spinning, this is already way above the cost of electricity per bitcoin.

PS: I didn't notice that you get 50 bitcoins per block. Things are starting to make sense.

You should generate on your GPUs, CPUs are pretty uneffective for generation.

Yes.  Generation is intentionally hard, otherwise it would be worthless as a trade currency.  It's much easier, and less costly to most people, to buy or trade for bitcoins rather than generate.  I've never generated a block, personally.

"The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. This system was to be controlled in a feudalist fashion by the central banks of the world acting in concert, by secret agreements arrived at in frequent meetings and conferences. The apex of the systems was to be the Bank for International Settlements in Basel, Switzerland, a private bank owned and controlled by the world's central banks which were themselves private corporations. Each central bank...sought to dominate its government by its ability to control Treasury loans, to manipulate foreign exchanges, to influence the level of economic activity in the country, and to influence cooperative politicians by subsequent economic rewards in the business world."

I'd like to do that, but I read something about someone making a client for GPU generation that would actually steal bitcoins. What's the best, and most secure, way to accomplish GPU mining?

Both work fine on my HD4870, but poclbm (first link) works with the newest official bitcoin binary.


Nobody is using the "stealing" version from puddinpop anymore.

If you're interested in getting a few bitcoins right now there's the faucet https://freebitcoins.appspot.com/, it isn't much but you can use the bitcoins to start playing with them.

Also if you prefer having a few bitcoins distributed more or less evenly over shorter periods you might want to try joining a generation pool, where all users contribute to one client which then divides the 50 coins according to who contributed what. http://www.bluishcoder.co.nz/bitcoin-pool/
