Ⅸ What should I do if I forget the bitcoin wallet address of the blockchain?
Have you backed up the private key file corresponding to the address? Just make a backup. There is no backup.

Generally, the backup wallet.dat is overwritten with the A of the new deviceppdata (hidden by default) is the default wallet file in a bitcoin directory, or you can “open” the backup wallet in the menu bar of the new client. However, it is not recommended to ensure the security of Bitcoin by backing up and restoring the wallet.dat wallet file of BitcoinCore, because wallet.dat contains not only private keys but also transaction records, so you may need to back up after each transaction, which is troublesome. The private key only needs to be backed up once and more than once. Without the wallet.dat file, is it not a bitcoin wallet? If you need N addresses, you can choose the hierarchical deterministic wallet HDWallet (this only needs to back up a string of ciphers) without the trouble of backing up N private keys. And if you use bitcoin with the same address on multiple devices (not recommended), pay attention to wait for device A to send coins to complete confirmation, and then send coins to device B after the transaction is completed synchronously on device B. Otherwise, if the A side does not confirm that you send it again from the B side, it may “double spend” and cause the second transaction to fail to be sent. What does “Warning! There are multiple payments for this transaction” mean?
