If BTC rises and dumps again then it will be dead unless it changes it's way of managing the block chain, the way it works now about an 8 cents per KWH of power is needed even to make a profit, once the halving comes if the hashing power stays the same then a 4 cents per KWH needs to be the rate. If anyone in the world can produce power at that rate please let me know as I want to be a reseller!
The interesting thing is hashing power keeps going up even though KNC went bankrupt!
Only people like you and I will keep the price up, if we stopped buying the price would drop to less than $100 then it would be upto the BTC community to change the way BTC works. As much as people hate to here this POW will not work in the long run and maybe a change to POS might fix the problem.
