On: Many Bitcoin Miners Are at Risk of Turning Unprofitable

> it is not the mining itself which creates the bitcoin

It is the hashing power of the mining which secures the bitcoin. It's nigh impossible to steal / double spend, and this is pretty revolutionary IMO.

That said, proof-of-stake and other options exist that might also provide adequate security while posing a smaller cost to the network.

That "might" is doing a lot of work. None of those options are really options yet (if ever).
