How would this effect bitcoin? would it cause us to regress back to a time where we actually counted bitcoin in bitcoins not satoshis, or would bitcoin become insanely expensive?
The bitcoin network will be broken, there is no nodes for securing the bitcoin network. All of the transaction will be reversible in my opinion. I can say bitcoin will die if all of the miners will be destroyed.
The key of bitcoin is on the miners to securing the bitcoin network and running it to be a bitcoin node.
