Because I want to solo-mine, instead of participating in the pool where my share will be tiny and even in case that pool discovers a block, my share of the reward would barely cover that tiny electricity cost which I consumed.

I don’t care for that money, instead I prefer to test luck and mine in entirely solo fashion, so that if I discover block, I get full reward. Chances extremely low but it’s a forever lottery for me, which can be regarded in this way.
