Can bitcoin exist without miners?
Can bitcoin exist without miners? In the past year only, the bitcoin mining difficulty has increased fivefold. If in the coming years the difficulty increases so much that mining is no longer profitable (i.e. consumes more power than creates $$), can the bitcoin network exist without miners? Can bitcoin supporters, or governments have data centers that handle transactions only and do not spend computational resources on mining new bitcoins? http://ift.tt/2l8KaDH
