A comment on Many Bitcoin Miners Are at Risk of Turning Unprofitable. Parent comment
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.
