I decided I wanted to peel and claim a 0.5BTC casascius coin. I am using electrum to try and sweep the wallet but am getting the error "no inputs found". When I import the private it key it gives me a balance of 0 and a receiving address entirely different from what the coin has on it. The analyzer says the coin is still funded. I bought it in 2013. Anyone have any idea what is going on or did I somehow get duped 4 years ago? Really needed the money
.
Thanks for any help!
See what wallet is associated with the private key, and check if it still has the 0.5 balance on it. If not, it's pretty likely that they indeed somehow got stolen.
Try
And see if there's been any outputs, or if the 0.5BTC is still there.
