Well, it is "wasted power" for sure. My 6000 kH is benefiting me only while consuming energy that doesn't benefit anyone else. Would be cool if there was some benefit for sure.
Security is not a benefit???
Security does not come for free, never.
Well, I'm not a doomsday prepper so I'm not really fearing an end-of-the-world-as-we-know-it scenario where some dude on the street takes my btc for milk and eggs.
Oh boy...i bet I just opened up a whole new can of worms.
LOL
