Bitcoin has reversed funds multiple times via hard forks. The only thing this article proves is that ethereum is young
The only time you are probably talking about is when someone made a block with a 9 billion bitcoin reward. Even then, they just convinced the miners to start a different chain. Thus, the chain with the 9 billion coins block just died. So yea, no reversal without a signature, ever!
I'm also referring to the march 2013 hard fork
so congratulations you just helped me prove my "multiple times" for the lay man
I never said the hard fork was specifically to target a particular transaction, the result is that every transaction on the dropped chain was reversed.
(But maybe I have entirely the wrong idea of what the attack vector was here)
