@whatsup,
This will be a bottle neck to BTC! Few months ago few of my friends installed a mining rig but due to power cost it's ROI is far far away! So, when it happens people will move to PoS and DPoS and the final result is bottle neck on transactions of PoW!
If WA can keep miners it's a good idea and a profitable thing if electricity becomes lower, but if they can't spend it, I just feel WTF :D
I don't think this proof type will have a long journey! So, better not invest on it! For me it's a sinking ship!

Cheers~
