Profitability of mining
As we have mentioned earlier, the Bitcoin network hash rate is really high now. Mining with a CPU is no longer guaranteed to bring in profits. This is due to the fact that, during the mining process, you are competing with other miners to try to solve a block. You will be at a disadvantage if those other miners are running faster hardware, as your hardware can only make a certain amount of guesses (hashes) in a given time frame.
To compare the mining speed of a few CPU's, look at the following table:
|
CPU |
Mining speed (KH/s) |
Power used (Watts) |
