Bitcoin the currency and protocol has never been attacked. I mean it is like saying I saw a 7-11 get robbed so obviously there is a critical flaw in the dollar.
My point is bitcoin doesn't exist on paper. It exists as bits inside a machine. Without that machine we cannot transact business to even write to the blockchain.
Cash can be transacted hand to hand. Bitcoin can't.
Focusing only on the math and not the machines and implementation is missing half the equation.
