Correct. But I would be CPU mining.... CPU being the slowest in the hierarchy of mining. My limited understanding was as faster and faster systems get involved in mining the difficulty in solving is increased. One reward is going to be issues every fixed period of time, so if three people with same equipment are mining I have a 33% of getting the reward. Having the slowest equipment for mining means I could run it 24/7 (and am while I'm on vacation for a week) and still not receive a reward because far superior equipment by many more people are competing for the same reward
