Do you understand then how subjective your definition of fungibility is?
Hey I'm just using the dictionary man
From your POV any medium of exchange that is suspect to traceability by any means is non fungible.
That is not what I said.
What I said is the intrinsic properties make something inherently fungible only when there is no useful traceability (or other physical distinguishability). Otherwise if individual units can be distinguished and then it is up to people, not technology or science, to decide whether it is fungible in practice or not. The obvious example here is paper money. Not only is it fungible by law (we'll ignore that here) but it is fungible only because people don't for the most part ever pay any attention to the serial numbers. If people started doing so, fungibility could only be restored by creating money (such as metal coins) without serial numbers.
Obviously intrinsic indistinguishability properties provide stronger fungibility than people do, and because the Bitcoin ledger doesn't have those properties, this thread exists.
About Bitpay blacklisting coins, what else can we add about the morons that just got hacked $2 million of their money via a simple email. No comment really!
Agree with you there but it isn't just them doing it.
