Ticket ID: 122010
I’m at a loss. I was sending BTC from the Trezor to Coinbase, I confirmed the transaction and I received my 0.02 BTC in my Coinbase. A month later I log into my hardware wallet and there is two transactions for the same amount and same day and same time showing two different TX ids. I contacted Coinbase and they are telling me the second transaction isn’t a Coinbase wallet address. However when I check the blockchain the change spend address for both transactions is the same. How can the change address be the same but both accounts not be Coinbase accounts? So either I’m hacked and have a Trezor from Satoshi Labs with some new cloning software or Coinbase is lying. I’m missing 0.02 BTC and no answers. Anyone know about how change addresses work? Can the same change address be used for two TX ids and the receiving addresses not be associated ?
