I've been undermining for almost 4 days with a Core2 Duo and to this day I do not have a single ONIX drive in my wallet, and that I'm using the difficulty: 0.002.

Attached is a catch where I only see 22 miners mining and with few positive results (mine is one of 28.63 KH). Is it so much the difficulty of mining?
