Wallets Explained

In a BIP44-style path, what does the second-to-last number (0 or 1) tell you?

• Which coin the address is for
• Whether the address is on the receiving chain (0) or the change chain (1)
• Whether the step is hardened

A restored wallet shows a zero balance. Which explanation fits most often?

• The seed phrase stopped working after a few years
• The app is scanning a different branch, or stopped at the gap limit
• The coins were moved to the wallet maker for safekeeping
