Private Key – After attempting to transfer with an imported key, I receive the following message: “The public key is neither compressed nor decompressed.”

I still have my old Bitcoin wallet (circa 2012) and its private keys. Download the bitWallet app for iOS, enter your private key there, and you will see your wallet with your balance and all your transactions. I wanted to transfer Bitcoin to a new wallet, but I got the following error:

Step 1: Insert your private key into the bitWallet (iOS) application and it will automatically calculate the correct address.
