Gold supporter Peter Schiff tweeted today that my bitcoin mystery has been solved. I mistaken my pin as a password, and when the blockchain updated their application, I was logged out. I tried to log in again with the only "password" pin I knew. I also never have a copy of my seed, which is a costly mistake! It is reported that Peter Schiff previously stated that he had lost all BTC, his wallet was somehow damaged, and the password was no longer valid.
