RE: Why Am I Cracking Open a Graded Casascius Physical Bitcoin?

in #bitcoin7 years ago

It's not impossible to counterfeit these Casascius holograms (in fact, there is evidence that someone did so at least once), but any prospective buyer can look up the address on the coin via Uberbills to see that it's still loaded, since all are on the blockchain. Most of them are sold via the same sites and if the same BTC address were to appear in repeated sales, it might raise a red flag.
