This question already has an answer here:

If I have 1000 (or more) machines with CPU (and no GPU) solo mining (12 hours/day), will it be profitable?

Forget about the costs of electricity, etc...

I want to know if doing more than 1000 machines solo mining (CPU) will win any bitcoin?

If those are reasonably decent CPUs, they could be able to mine up to 20 Mhash/s each. Together, that's 20 Ghash/s, or the same as a small ASIC, and using massively more electricity.

As of december 2013, with the difficulty at 707408283, this means that you'd have approximately a 0.85% chance per month to win a block (worth 25 BTC).

  • nice! Tks! tell me... out of the possibility to win a block, just the act of "mining" win some bitcoin? – user9829 Dec 1 '13 at 23:05
  • I don't understand what you're asking now. – Pieter Wuille Dec 3 '13 at 0:14
  • Oh, if you don't solo-mine, and join a pool, you will earn approximately the same on average (0.85% * 25 BTC = 0.21 BTC per month). – Pieter Wuille Dec 3 '13 at 0:20
