that's why I said divide by 100 to account how many are off.
You're missing the point. Why would I have a miner running on my phone if it ups battery drain so I have to recharge the phone every 30 minutes instead of every 18 hours.
ok because, say in 2 years, time, your phone will be so much more powerfull it would not be taking whole battery, also only a portion of the network is ever on and hashing, eg 1/100 th, that's why I divide by 100, my combined hash will far out do anything else and increasingly so over time due to the investment into mobile devices/phone, thier subsidy by other uses and ther shear number of them.
I think the person to crack this paradigm, will have BTC 2.0, with a take up rate that is well frihgtening. I think the blockchain would have to be premined for say 1 million -1 billion coins and every one that starts mining can get 1 coin automatically, and no premines are coins are kept, or perhaps 1000 only to recover costs.
